The movement of the leaves of a sensitive plant is non directional.

It just FOLDS itself independent of the DIRECTION of the STIMULUS(TOUCH here).

However the movement of a shoot towards light is directional. It depends on the direction of the stimulus (light here).........

During VOLUNTARY CONTRACTIONS, a STRIATED muscle is extended by the action of an antagonistic muscle. ... The fibers ofstriated muscle have a cylindrical shapewith BLUNT ends, WHEREAS those in smoothmuscle can be described as being spindle-like with tapered ends.

The gynoecium of a MUSTARD plant is described as syncarpous because it is United

Explanation:

• the flower is the organ of sexual reproduction in case of plants. The gynoecium is the female sexual organ of the sexual part which is present in case of plants. The morphology of the gynoecium is different for different plants.
• In case of mustard the The gynoecium is United in such a way that they APPEAR as a single unit. As a result of this they are known as syncarpous

Hey mate... COLOUR BLINDNESS is your ANSWER!!

here are some details about it....

Color blindness, also known as color vision deficiency, is the decreased ability to see color or DIFFERENCES in color. SIMPLE tasks such as selecting ripe fruit, CHOOSING clothing, and reading traffic lights can be more challenging.Color blindness may also make some educational activities more difficult. HOWEVER, problems are generally minor, and most people FIND that they can adapt.People with total color blindness (achromatopsia) may also have decreased visual acuity and be uncomfortable in bright environments.

ANSWER....

Heredity - it refers to the transmission of characters are trade from parent to their offsprings. it is the continuity of features from one generation to another which are present in fertilized egg or zygote. the zygote develops into an ORGANISM of a particular type only.

Genes - it is the BRANCH of Biology which deals with heredity and variation. Genetics is to help our understanding and heredity by knowing how of a spring inherit characteristic from their parents.

Variation - it MEANS the difference in the characters among the individual of a species.

Causes of variation :-

1. different combination of a genetic material.

2. some positive gene mutation .

3. interaction of gene with environmental changes.

Importance of variation:-

1. IT form with the basis of heredity.

2. it cause adaptation due to which organism can easily adjust with changing environment.

3. ACCUMULATION of variation form the basis of evolution.

Genotype - the genetic constitution of an organism is called genotype.

Phenotype - the appearance of organism is called a phenotype.

Gene - basic unit of heredity which contain chromosome is called gene.

chromosomes - these are long thread is present in nucleus of EVERY cell.

Allele - it is an alternative form of gene occupying the same position on a chromosome and affecting the same characteristic but into alternative ways.

Homozygous - when both alleles of a particular gene are the same is called homozygous.

Heterozygous - when both alleles of particular gene are different are called heterozygous.

Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. ... Genetic variation is advantageous to a population because it ENABLES some INDIVIDUALS to adapt to the ENVIRONMENT while MAINTAINING the survival of the population.

Infections are caused by infectious AGENTS including viruses, viroids, PRIONS, bacteria, nematodes such as parasitic roundworms and pinworms, arthropodssuch as ticks, mites, fleas, and lice, FUNGI such as ringworm, and other macroparasites such as tapeworms and other helminths.
Hosts can fight infections using their immune system. Mammalian hosts react to infections with an innate response, often involving inflammation, followed by an adaptive response.[3]
SPECIFIC medications used to TREAT infections include antibiotics, antivirals, antifungals, antiprotozoals, and antihelminthics. Infectious diseases resulted in 9.2 million deaths in 2013 (about 17% of all deaths).[4]The branch of medicine that focuses on infections is referred to as infectious disease.

In general: NASAL breathing is healthierthan mouth breathing for several reasons. ... Exhaling through the nose, which is smaller than the mouth, creates greater air PRESSURE andtherefore a slower exhalation. This GIVES the lungs EXTRA time to extract agreater amount of oxygen

The term ecosystem describes both the living and non-living components of an area that interact with one another. All the components are inter-dependant in some way with each other. An ecosystem may be AQUATIC or terrestrial.

In an aquatic ecosystem rocks are needed for shelter and plants provide oxygen for fish. An ecosystem is BALANCED when the natural animals and plants and non-living components are in harmony- i.e. there is nothing to disturb the balance. With increasing pollution, change in migratory patterns, and rise of human population, many ecosystems are in danger of losing that harmony.

Advantages
It is difficult to find a perfectly balanced ecosystem but you can make a model at home and observe how the ecosystem functions.You can observe how different species interact with each otherStudy the natural cycle of each speciesUnderstand the relationship between different species- producer, predator, prey
How to create a balanced ecosystem model
Here is a suggestion for making an aquatic ecosystem- an aquarium. You will NEED: 
River silt or clean sand for the aquatic plants to grow.

An aquarium tank, at least 1 foot wide, 2 feet deep and 2.5 to 3 feet long. The top of the tank should be detachable and foldable so that you can reach into the aquarium to clean the glass sides and also feed the fish.

A light attached to the top lid to provide ARTIFICIAL light and for warming during cold winters. You can also place the aquarium at a sunny place.

Aquatic plants.

Small rocks for the bottom.

Fish.
First clean the soil and put it in the bottom of the tank. Arrange the rocks. Then pour a little WATER into the tank. Pouring the water directly will disturb the soil bed; so pour it over a plastic plate that floats over the surface of the water.

This way you will not disturb the bed or any other plants or fish when you pour water. When the water is at least 1 inch higher than the bed, put the plants into the soil. As the water level goes up the leaves of the plants will also rise up.

After the tank is full with about 4 inches left on top, stop pouring the water. Let the water settle for some time. Now introduce the fish one by one and close the top.

Hey mate...!!!!
RECYCLE means to CONVERT a material which has no USE into an USEFUL material.
Example– Recycle the cans that means make a new material from the can...so that it can be used in a different work.


Reduce means to decrease use of a material if we have no use of it.
Example– Switch off the lights of your rooms if you don't need it...etc.

Reuse means to again use the material we have which has no use.
Example– If we wash CLOTHES..... don't throw the water used in it... use it in cleaning the house..etc.

Harvesting is the process of gathering a ripe crop from the fields. Reaping is the cutting of grain or PULSE for harvest, TYPICALLY using a SCYTHE, sickle, or reaper. On smaller farms with MINIMAL mechanization, harvesting is the most labor-intensive activity of the growing season.

Emasculation of a human MALE is the removal of both the penis and the TESTICLES, the external male sex organs. Depending on the context, this may be seen as CONSENSUAL body modification, or non-consensual GENITAL mutilation. The word ALSO has other meanings which are more commonly used.
