In EMBRYONIC DEVELOPMENT
one month= heart is formed.the first sign of growing feotus may be noticed by listening to the heart sound.

Second month = the foetus develops limbs and digits.

Third month (first trimester / 12weeks)= most of the major organ are formed . the limbs and external genitalia organ are well developed.

Fifth month= the first MOVEMENT of foetus.
appearance of HAI on head are usually observed.

24 weeks ( end of second trimester )= the body is covered with fine hair, eyelids separate and eye lashes are formed.

The PLANTS like Corn, Sugar Cane, Palm oil, Jatropha, SOYBEAN, SWITCHGRASS, RAPESEED are cultivated to OBTAIN the fuel. The method ofproducing fuel from plants or other sources will allow us to decrease our dependence on fossil fuels specially Petroleum products

PANCREAS is both an ENDOCRINE and an EXOCRINE GLANDS

Phylum Porifera

These are the simplest multicellular animals, found mainly in marine habitats. These organisms have pores all over the body. They have a canal system that helps in circulating water and food particles and oxygen. The body design shows minimal differentiation and division of tissues. Commonly called as Sponges, some of the examples are Spongilla, Sycon etc.

Phylum Coelenterata

These organisms show more body differentiation. They live in water. The body has a sac-like cavity, with a single opening for ingestion an egestion. These animals have two germ layers and hence are called diploblastic. You can see these animals living solitarily or n colonies. Examples include JELLYFISH, Sea Anemone, and Hydra.

Phylum Platyhelminthes

These are commonly called flatworms. Their bodies are flattened dorsoventrally. They are the first triploblastic animals, with three germ layers. The body is also bilaterally symmetrical, with both the left and right halves of the body having the same design. Flatworms can be either parasitic or free living. A few examples are Planaria, Liver Fluke, and Tapeworm.

Phylum Nematoda

The bilateral symmetry and triploblastic nature continue in these animals. The body, however, is more cylindrical and not flattened.  The body cavity is not a TRUE coelom. And hence it is called a pseudo coelom. Tissues are present, but organs are absent. These organisms show a complete ALIMENTARY canal which is straight. Most of these organisms belonging to this phylum are parasitic worms, which cause diseases. Examples are Ascaris, Wucheria.

Phylum Annelida

Annelids are found in different habitats, such as land, fresh water, and even marine mater. They have a bilaterally symmetrical body with three germ layers (Triploblastic). A distinguishing feature here is that they have a true body cavity. The body is also segmented with some organ differentiation seen. Examples are Earthworms, Leeches.

Phylum Arthropoda

They make up the largest group in the animal kingdom. Most of the insects are included in this phylum. “Arthropoda” means jointed legs. The bodies of these animals are divided into head, thorax, and abdomen. Apart from the jointed legs, they also have a pair of compound eyes. Another distinguishing feature of these animals is the presence of an open circulatory system. Examples are butterfly housefly, spiders, mosquitoes, crabs etc.

Phylum Mollusca

The bilateral symmetry and the triploblastic nature of the body layers are seen here too. Molluscans form a very diverse group and form an important part of the ecosystem. These animals can be seen aquatic habitats. They can be either marine or freshwater species. The body does not show much segmentation and the coelomic cavity is also reduced. The body is TYPICALLY divided into anterior head, ventral muscular foot, and a dorsal visceral mass. The foot helps in the locomotion of the animals. Examples are Snails, Mussels, and Octopus.

Phylum Echinodermata

Moving on with the classification of animals we come to Phylum Echinodermata. Echinoderms are animals with spiny skin. They live exclusively in a marine habitat. They are free-living animals. The larvae show bilateral symmetry whereas the adults show radial symmetry. These animals are triploblastic and have a coelomic cavity. They have a peculiar water driven tube system that helps them in moving around.  They also have a hard exoskeleton that is made up of calcium carbonate. Examples are Starfish, Sea cucumber, Sea Urchin.

Phylum Protochordata

The protochordate animals are bilaterally symmetrical and triploblastic. They have a coelom. A new body feature that is seen in these animals is the presence of notochord at some stage in their life cycle. Due to this very presence of a notochord, they are called as chordates. However, it is sometimes rudimentary. They are exclusively marine animals. Examples include Herdmania, Balanoglossus.

Phylum Vertebrata

These are the ADVANCED group of animals, showing some really advanced features of a proper digestive system, circulatory system etc. There is a complex differentiation of body tissues and organs. These animals have a true vertebral column with an internal skeleton. All chordates have the following features:

Plasma contains anti-A and anti-B antibodies DEPENDING on BLOOD group . Group AB recipients can only RECEIVE group AB plasma.

The Philbrick Company has two plants on OPPOSITE SIDES of the United States. Each of these plants produces the same two products and then sells them to wholesalers within its HALF of the country. The ORDERS from wholesalers have already been received for the next 2 months (February and March), where the number of units requested are shown below. (The company is not obligated to completely fill these orders but will do so if it can without decreasing its profits.)

Each plant has 20 production days available in February and 23 production days available in March to produce and ship these products. Inventories are depleted at the end of January, but each plant has enough inventory capacity to hold 1,000 units total of the two products if an excess AMOUNT is produced in February for sale in March. In either plant, the cost of holding inventory in this way is $3 per unit of product 1 and $4 per unit of product 2.

Each plant has the same two production processes, each of which can be used to produce either of the two products. The production cost per unit produced of each product is shown below for each process in each plant.

A primary METABOLITE is a kind of metabolitethat is directly involved in normal growth, DEVELOPMENT, and reproduction. It usually performs a physiological function in the organism (i.e. an intrinsic function). A primary metabolite is typically present in many organisms or cells. It is also referred to as a central metabolite, which has an even more restricted MEANING (present in any autonomously growing cell or organism). Some COMMON examples of primary metabolites INCLUDE: lactic acid, and certain amino acids. Note: Primary metabolites do not show any pharmacological actions or effects.

Thank You!

It's MAY be on the RIGHT SIDE

The over use of an organ cause its growth and that CHARACTER is transmitted to next generations.
eg: LENGTH of the neck of Giraffe increased due to feeding the leaves of higher TREES .
This theory faced criticism by many scientists.They raised the question that how aquired CHARACTERS transmit to next generations?
only genetically evolved characters transmit to next generations

The oxygenated blood and the DEOXYGENATED blood in the heart do not get it because they are the both DIFFERENT blood which flow in different ARTERIES and they both get in different compartment of the blood that's why they do not get mix with each other

Hello Friend ✌

✨The Theory of Natural Selection.Darwin's theory is based on threepostulates:

The ability of a population to EXPAND is INFINITE, while the resources available to SUSTAIN said population are finite. This dynamic causes a struggle for existence among individuals as they compete for resources.

Hope This HELPS u ☺.

The only classical natural disaster I've been in is a 5.x earthquake when I was 6. Home alone, I had no idea what to do or what earthquakes are, so I figured it was something I did and that if anything fell and broke, I'd get the blame. So I gathered all my stuffed animals and put them under the bar with all the alcohol bottles, wherever there was a table with a vase, and wherever there were framed photos. As soon as I finished, the earthquake stopped, so I quickly gathered them up before my mother came back home so she'd think nothing happened.

For something far more dangerous, I did nearly die in an unseasonable storm. It doesn't count as a natural disaster, but close enough. We were practicing how to make geological maps in the Austrian Alps. Groups of two, each group gets a region. We got lucky, our region was very large but mostly flat with one small mountain and a large, much more complex one. We DECIDED to do that one in one go, since my partner has VERTIGO and can't stand mountain climbing. So on the scheduled day, we got up to half the mountain. Most of the mountain was made up of a type of marl which is slippery even when dry, so it was fairly treacherous, especially with the incompetent with me.

But then a storm rolled in completely unexpectedly. Torrential rain with hail. We were in the middle of the forest, spidering our way up to the top of the mountain on a ~80° slope. I used the marl outcrops as footholds when there was no tree, but I had no idea that when they got wet, they have as much grip as Vaseline. So I slipped and rolled down several tens of meters and crashed belly-first into a tree. When I recovered from the blow, I noticed blood on my hand and noticed that the compass around my neck was gone. It turns out that I had just missed getting my jugular punctured by some sharp rock on the way down, and my neck was bleeding out. Luckily the first aid kit was still there, as well as the Jägermeister. I had cracked a couple of ribs and sprained my wrist, so there was no going up or down the mountain. We ended up tying ourselves to each other with a rope. My partner was overweight, I was underweight, so I had my partner crawlhis way to the regular path while I SHOUTED words of psychological encouragement to make him get over his fear and vertigo. We then walked down Mount DOOM, and WENT back to our youth hostel. Luckily, we had gone far enough up the mountain that we discovered all the parts to it, so no need to go there anymore.

This paper presents recommendations for the analysis and PRESENTATION of height and weight DATA from surveillance or surveys involving nutrition and anthropometry in young children up to the age of 10 years. These recommendations are only for the analysis of data collected on a cross-sectional basis. The basic INDICES recommended are height for age and weight for height, each considered either in terms of centiles or in a cross-classification scheme using standard deviation scores. It is hoped that these methods of analysis and presentation will prove widely acceptable, so that international comparisons will be MADE easier.

It is HEART it is myogenic in NATURE

1. Plant them in places conducive to growth  

2. Put water on them  

3. Put fertilizer on them  

4. Remove weeds from the area around the more desirable plants  

5. Remove insects (and other animals) from the area around the crops  

6. Determine the optimal spacing for the plants, and plant them that way  

7. Determine the optimal fertilizers in terms of both "what" and "how much" and apply them that way  

8. Follow good crop rotation / leaving fallow schedule to  

reduce soil nutrient depletion;  

and/or reduce things LIKE selenium contamination which come from using a substandard water supply  

9. Occasional plowing before PLANTING can break up old root clumps and give the new plants a better chance at growing their own roots. Do not overdo (which can lead to accidental wind blowing away of the topsoil).  

10. SELECTIVE breeding of plants for improved per-acre yield. This can include breeding for response to fertilizers, salt TOLERANCE, disease resistance.  

11. Genetic engineering of crop plants for improved nutritional value, improved disease resistance, resistance to herbicides.  

Lifestock:  

1. Make sure the animals get adequate food and water  

2. Selectively breed the animals for weight gain per unit food  

3. Give the animals better quality food  

4. Bring the food to the animals rather than BRINGING the animals to food. This means less energy is wasted in walking to and from pastures and that means more weight is put on.

Hope it helps you...

Adolescence comes with its fair share of changes, many of which can sometimes worry parents; these transformations can be physical, For many teens and their parents, adolescence is a stage of life that is highly emotional and full of highs and lows. This delicate period of change is a time when the teenager establishes, step by step, his or her personality and independence.

Physical changes

The physical transformations observed during adolescence are, in most cases, the result of hormonal changes as the teenager’s body is transformed from child to adult. This PHASE, called puberty, starts between the ages of 9 and 16 and usually ends between the ages of 18 and 22. Puberty OCCURS at different times for everyone. The sexual hormones are responsible for these physical changes; a boy’s body produces more testosterone while a girl’s body produces more estrogen.

Physical changes observed in both girls and BOYS INCLUDE growth spurts, increased perspiration, acne problems and appearance of pubic and underarm hair.

Here are a few other examples of typical changes in boys:

broader shoulders and chest;voice changes;appearance of hair (chest, arms, face);development of genital organs;first erections.

And girls:

development of breasts;first menstruations;broader hips.

In general, the first signs of puberty appear earlier in girls than in boys.

Psychological and emotional changes

Adolescence is not only characterized by the aforementioned common physical changes. Indeed, this stage of life is full of emotional and psychological transformations that are just as significant as physical ones.

Teenagers search for their own IDENTITY and feel a growing need for independence. This period is also one of confusion, when the teen is torn between the desire for autonomy and the need to remain dependant on his or her parents.

Friendships also become more important. In addition, peer pressure increases and changes in behaviour are observed, sometimes creating conflicts between teenagers and their parents. Feeling carefree and invulnerable, teens seek new experiences and can sometimes get exposed to situations that are dangerous or harmful to their health and well-being: smoking cigarettes, drinking alcohol, taking drugs, reckless driving or sexual behaviour, etc.

As we explained above, puberty is the result of hormonal changes that, in addition to being responsible for the physical transformations of adolescence, lead to mood swings. This requires a lot of patience and understanding from the teen’s loved ones. Adolescence also involves countless difficult decisions to be made by the teen, which can cause all kinds of different feelings. 

sychological, emotional, sexual, etc.

When children reach puberty, a new type of sweat gland develops in their armpits and genital areas. Skin BACTERIA feed on the sweat this type of gland produces, and this can lead to body ODOUR (BO).

If your child washes her body and changes her clothes regularly, especially after  physical activity, it’ll help to reduce the build-up of bacteria and avoid BO. Changing underwear and  other clothes worn next to the skin is especially important. These  clothes collect dead skin cells, sweat and body fluids, which bacteria love to eat. That’s why they get smelly.

The onset of puberty is also  a good time for your child to START using antiperspirant deodorant. You can encourage your child to do this by letting him choose his own. Note that there are many PRODUCTS that are deodorants but not antiperspirants. These simply cover up odour. Antiperspirants stop BO by controlling the AMOUNT of sweating.

Hope it helps..

Pine TREES gernally grows in snowy AREAS they have slipy leaves so that the SNOW will GO to GROUND

The squamous epithelium (PAVEMENT epithelium) is made up of a single thin layer of FLATTENED cells with irregular boundaries. They are FOUND in the walls of blood vessels and air sacs of lungs and are involved in a FUNCTION like forming a diffusion boundary.

there is no DIFFERENCE in the arrangement of the chromosomes. Transgender PEOPLE are biologically BORN as male or female but they identify with the opposite GENDER.

They will have the same arrangement of chromosomes from when they are born. its just that they identify with the opposite gender than their own.

The process of respiration in plants involves using the sugars produced during PHOTOSYNTHESIS plus oxygen to produce ENERGY for plant growth. In many ways, respiration is the opposite of photosynthesis. In the NATURAL environment, plants produce their own food to survive.

They use Carbon Dioxide (CO2) from the environment to produce sugars and Oxygen (O2), which can later be used as source of energy. While photosynthesis takes place in the leaves and stems only, respiration takes place in leaves, stems and roots of the plant. The process can be REPRESENTED as follows:
