They have ENERGY i the FORM of ATP

Receptors are present in our all parts of the body for example in skin, eye, nose tongue etc. They detect the signals and then send them to BRAIN in the form of electrical signals.

Receptors can become DYSFUNCTIONAL temporarily or sometimes permanently depending upon the level of exposure to a certain stimulus. For ex- laser beam ENTERING DIRECTLY into the eyes can burn the retinal cells and can make a person temporarily or permanently blind, depending upon the length of period for which the exposure sustains. SIMILAR is the case of burns. A mild burn can desensitize the skin for some time but a significant burn can cause a permanent loss of sensation in the burnt area.

The associated problem includes loss of stimulus from that particular receptor, which is certainly not good for the coordination in the body.

Mitochondria is called semi AUTONOMOUS because it GENERATES energy in the FORM of ATP(adenosine TRIPHOSPHATE) molecules

Here is your answer. ..

Biological WEED and pest control -....

Weed MEANS UNWANTED CROPS in the field. for removing this unwanted plants farmers use weedicides.

Pest is a like diseases it causes by any particular insects.

For controlling it farmers use pesticides. ..

This is all control by biological weedicides or pesticides.

hope it helps you. ☺

Ans. An ORGANISM uses OUTSIDE raw materials mostly in the form of FOOD and oxygen. The raw materials REQUIRED by an organism can be varied depending on the complexity of the organism and its environment.

HEY MATE ______

HERE IS YOUR ANSWER _______

==============================

Eyes are DERIVED mostly from the neural
ectoderm ,the LENS in derived from the surface ectoderm .

=================================

Cellular Respiration Photosynthesis
Occurs in all living organisms .
Occurs only in all green plants , algae , and in some bacteria .
The ENTIRE process occurs in Mitochondria .
The entire process occurs in Chloroplasts.
Glucose and OXYGEN are the reactants of this process .
Carbon dioxide, water, and light energy are the reactants of this process.
Carbon dioxide, water , and energy ( ATP ) are the by -products .
Glucose, oxygen , and water are the by -products.
Undergoes Catabolic Process.
Undergoes Anabolic Process.
Oxygen is taken in and carbon dioxide is liberated out .
Producing food and capturing energy .
In this process, food particles are broken down to release energy .
In this process, food is synthesis by capturing the energy .
It is an exergonic reaction as energy is RELEASED .
It is an endothermic reaction as it requires energy .
This process does not require sunlight since cellular respiration occurs all the time .
This process requires sunlight since photosynthesis occurs only in the PRESENCE of sunlight .
The chemical reaction of cellular Respiration is
C 6H12 O6 + 6 O2 → 6 CO2 + 6H 2O
The chemical reaction of photosynthesis is
6CO 2 + 6H2 O → C 6 H12O 6+ 6O2

The FATS DIGESTED in our STOMACH

1.) Cuticle is waxy LAYER produced by EPIDERMIS , it is a water-proof layer therefore it has to be thick. It is absent over roots.

2.) The DISTRIBUTION of stomata is done over the leaf as for better inhalation of CO2

3.) The SIZE of the leaf is proportional to the inhalation of CO2 according to the plant.

Hello ABHISHEK...
good morning...

The amount of AIR remains in lungs after maximal exhalation is called Residual Volume.
it's VALUE is about 1200 ml.

hope it will HELP you...
BEST of luck...

In unicellular simple, diffusion will provide all essential nutrients this is beacuse the whole body is in direct CONTACT with the environment so no transport SYSTEM is REQUIRED to transfer the requirements.

Whereas multicellular organism have many organs ,where which all organs don't have so direct contact with it HENCE to full-fill this demand they need some especial way of transpiration and excretion.

Saliva CONTAIN enzyme Salivary emylase which converts CARBOHYDRATES into maltose . in mouth only 30 carbohydrates DIGESTION takes PLACE . There is no digestion of protein with the help of saliva

Endoplasmic reticulum. Smooth ER, by contrast, is not associated with RIBOSOMES, and its functions differ. The smooth ER is involved in the SYNTHESIS of lipids, including CHOLESTEROL and phospholipids, which are used in the production of NEW cellular membrane. In CERTAIN celltypes, smooth ER plays an…

Hello FRIEND...

Diarrhoea may be caused by MANY conditions like food poisoning, INDIGESTION and due to amoebiasis. Amoebiasis caused by ENTAMOEBA histolytica. Diarrhoea can be treated by some medicine and the most important thing is ORS. it's very important because it prevents dehydration.

hope it will help you...

ADVANTAGES OF BT COTTON —
a. BT cotton successfully repels the boll weevil larvae, one of the pests of cotton plants, and other LARVAL insects that HARM the plant; eliminating the necessity for pesticides.
b. There are no potentially physical health HAZARDS, while in the form of semi fabrics or raw material.

DISADVANTAGES OF BT COTTON —
1. We don't know the consequences of inserting the BT gene into the cotton gene pool.
2. Since it affects all larval insects, there are chances that beneficial caterpillars in the area will be killed too.
3. Famous cotton based firms like Monsanto might put special crop seeds out of the reach of developing countries, who may require them to protect already-polluted groundwater, environment, etc.
4. It is ecologically a hectic task to cultivate such a crop, due to its need of pesticides for 8-10 times in a single season (to get a decent YIELD). This requires a tractor, and subsequently its fuel as well as the farmer's time and money.
5. It poisons the groundwater and is a health hazard to humans and other organisms.  

Sun is the ULTIMATE source of ENERGY for all living organisms because all living organism need OXYGEN to breathe and this oxygen PRODUCED by the plant during photosynthesis in photosynthesis plant need SUNLIGHT to during reaction

The endoplasmic reticulum is a TYPE of organelle found in EUKARYOTIC cells that forms an interconnected NETWORK of FLATTENED, membrane-enclosed sacs or tube-like STRUCTURES known as cisternae. It's also known as the highway of the cells.
TYPES:
1)Smooth ER
2)Rough ER

-bacteria PRESENT in the mouth degrade the sugar and food particles which RESULTS in pH LESS than 5.5
- it corrodes the mouth

Answer:

WIND-pollinated plants do not INVEST in resources that attract pollinating organisms, such as SHOWY flowers, nectar, and scent. INSTEAD, they produce larger quantities of light, dry pollen from small, plain flowers that can be CARRIED on the wind.

A hypotonic solution is any solution that has a lower osmotic pressure than another solution. In the biological fields, this generally refers to a solution that has less solute and more water than another solution.
A hypertonic solution is a particular type of solution that has a greater concentration of solutes on the OUTSIDE of a cell when compared with the inside of a cell.
An isotonic solution is one that has the same osmolarity, or solute concentration, as another solution. If these TWO solutions are SEPARATED by a SEMIPERMEABLE membrane, water will flow in equal parts out of each solution and into the other.

1. It is the DUTY of all of us also to plant trees near our surroundings and also to motivate others to do the same.

2. Breeding PROGRAMS for endangered SPECIES should be organized.
3.. Some of the laws should be MADE to ban the killing or capturing of endangered animals or birds. It should be made a punishable offense. Such laws should be enforced strictly and should not remain on paper only.
4. Indiscriminate killing of WILD birds and animals, whether are in abundance should not be allowed by the forest authorities.

A particular function is carried out by a group of CELLS at a definite PLACE in the body. Similarly, different functions are carried out by different GROUPS of cells in anorganism and this is known as DIVISION of labour in multicellular organisms

The vacuoles are found in certain plant cells and unicellular organisms. They help in many ways; mainly in separating SUBSTANCES (e.g. substances meant for degradation, other chemicals, wastes ETC) from the rest of the cytoplasm. They also have enzymes to degrade infecting bacteria. The vacuoles have many other roles as well.
