Chlorophyll is a pigment found in the thylakoid membranes of the chloroplasts in theleaves.

This is why plants aregreen. The simple answer is that plants aregreenbecause they havegreenchloroplasts (organelles that carry out photosynthesis).

Chlorophyll is a pigment that absorbs red and blue light

Thefemale mosquitois the one that bites (males feed on flower nectar). She requires blood to produce eggs. Her mouthparts are constructed so that they pierce the skin, literally sucking the blood out.

The female mosquitoes ofCulexand most other species lay their eggs in batches of 50 to 100, often in tiny clumps about a quarter-inch long that float together on the surface of the water like a raft. They make those deposits on water that's collected in tree holes, ditches, even your dog's water dish.

However, some species will lay mosquito eggs on moist, often-flooded soil in anticipation of the next rise in water. Those eggs can survive winter, waiting for spring or summer rains to cover them over.

Females usually deposit their eggs at night, and can lay them about every third night, up to three times.

Entomologists at Oklahoma State University report that the eggs are white when first deposited, then darken to near black within a day. They will hatch in one to three days, depending on the temperature. Eggs left on moist soil can last for up to a year, until the ground is flooded again, before hatching.

Mosquitoes of the genusCulexlay hundreds of eggs connected together to form a raft which floats on the surface of still water in a place like a pond, swimming pool, ditch, discarded tire or even a sewage cesspool. When the eggs hatch about a day later, the larvae wriggle free from the bottom of the eggs, swimming directly down into the water. They look like strange alien creatures.

egg laying female mosquito is anopheles.

Most of the organisms that are affected by the change in temperature are poikilothermic animals. The external temperature of their surroundings affects their internal temperature and thus, causes changes in their metabolic activities.

Organisms which can tolerate awide range of temperatures are called as Eurotherm and the organisms that have a narrow tolerance range of temperatures are called as stenotherms.

As the temperature of water goes 4°C, the density of water decreases. So, this causes a decrease in the buoyancy of the plankton and they tend to sink with increasing temperature of the water.

The reproductive life of the fishes is most commonly affected by the temperature changes. Trout fish reproduces at a temperature of3 - 14°C. However, when the temperature is above 24°C, it becomes lethal for the fish.

The optimal growth temperature of Carp fish is in between 20 - 30°C.

Many aquatic animals tend to change their colour with changes in the temperature. The animals that are active during the cold season are usually dark in colour.

LIKE THE SOLUTION

Carbon has a sedimentary cycle.

Ans :- The menstrual cycle is the regular natural change that occurs in the female reproductive system that makes pregnancy possible. The first period usually begins between twelve and fifteen years of age, a point in time known as menarche.

Usually, one egg is released from an ovary every month. Before the egg is released, theliningof the uterus becomes thick and spongy to prepares for a fertilised egg. It is full of tiny blood vessels, ready to supply the embryo with food and oxygen if it should arrive.

If the egg is not fertilised, it is dead by the time it reaches the uterus.

Is does not sink into the spongy wall, but continues onwards, down through the vagina.

As the spongy lining is not needed now ---> it gradually disintegrates and is slowly lost through the vagina.

This is called menstruation, or period and it last for about 5 days.

Thecell cycle, orcell-division cycle, is the series of events that take place in acellleading to duplication of its DNA (DNA replication) anddivisionof cytoplasm and organelles to produce two daughter cells. Inbacteria, which lack acell nucleus, the cell cycle is divided into the B, C, and D periods. The B period extends from the end of cell division to the beginning of DNA replication. DNA replication occurs during the C period. The D period refers to the stage between the end of DNA replication and the splitting of the bacterial cell into two daughter cells. In cells with a nucleus, as ineukaryotes, the cell cycle is also divided into two main stages:interphaseand themitotic(M) phase (includingmitosisandcytokinesis).

During interphase, the cell grows, accumulating nutrients needed for mitosis, and undergoes DNA replication preparing it for cell division. During the mitotic phase, the replicated chromosomes and cytoplasm separate into two new daughter cells. To ensure the proper division of the cell, there are control mechanisms known ascell cycle checkpoints.

The cell-division cycle is a vital process by which a single-celledfertilized eggdevelops into a mature organism, as well as the process by whichhair,skin,blood cells, and someinternal organsare renewed. After cell division, each of the daughter cells begin theinterphaseof a new cycle. Although the various stages of interphase are not usually morphologically distinguishable, each phase of the cell cycle has a distinct set of specialized biochemical processes that prepare the cell for initiation of the cell division.

The 23rd chromosome is made up of two parts – either two X chromosomes if you are female or an X and a Y chromosome if you are male. The faulty ‘gene’ for colour blindness is found only on the X chromosome. So, for a male to be colour blind the faulty colour blindness ‘gene’ only has to appear on his X chromosome. For a female to be colour blind it must be present on both of her X chromosomes.

If a woman has only one colour blind ‘gene’ she is known as a ‘carrier’ but she won’t be colour blind. When she has a child she will give one of her X chromosomes to the child. If she gives the X chromosome with the faulty ‘gene’ to her son he will be colour blind, but if he receives the ‘good’ chromosome he won’t be colour blind.

A colour blind boy can’t receive a colour blind ‘gene’ from his father, even if his father is colour blind, because his father can only pass an X chromosome to his daughters.

A colour blind daughter therefore must have a father who is colour blind and a mother who is a carrier (who has also passed the faulty ‘gene’ to her daughter). If her father is not colour blind, a ‘carrier’ daughter won’t be colour blind. A daughter can become a carrier in one of two ways – she can acquire the ‘gene’ from a carrier mother or from a colour blind father.

This is why red/green colour blindness is far more common in men than women.

Blue colour blindness affects both men and women equally, because it is carried on a non-sex chromosome.

Dichlorodiphenyltrichloroethane, commonly known asDDT, is a colorless, tasteless, and almost odorlesscrystallinechemical compound, anorganochlorine, originally developed as aninsecticide, and ultimately becoming infamous for its environmental impacts. It was first synthesized in 1874. DDT's insecticidal action was discovered by the Swiss chemistPaul Hermann Müllerin 1939. DDT was used in the second half ofWorld War IIto controlmalariaandtyphusamong civilians and troops. Müller was awarded theNobel Prize in Physiology or Medicine"for his discovery of the high efficiency of DDT as a contact poison against severalarthropods" in 1948.

Ans :- Concept learning also refers to a learning task in which a human or machine learner is trained to classify objects by being shown a set of example objects along with their class labels. The learner simplifies what has been observed by condensing it in the form of an example.

Edward Jenner introduced vaccine for small pox disease in 1796

principleTo produce an immune response, live attenuatedvaccinesmust replicate (grow) in thevaccinatedperson. A relatively small doseofvirus or bacteria is administered, which replicates in the body and creates enoughofthe organism to stimulate an immune response.

Vaccination is the administration of antigenic material (a vaccine) to stimulate an individual's immune system to develop adaptive immunity to a pathogen.

(i) Asexual mode of Reproduction : Only one parent involved.Sexual mode of Reproduction : Two parents (male and female) involved.(ii)Species that reproduces sexually have better chances of survival because more variations are produced during DNA copying which means that there is combining of germs cells of two different individuals (having quite different patterns of accumulated variations.)

One main difference between sexual and a sexual reproduction is that sexual reproduction involves fusion of gametes derived through either same parent or different parents but having produced through meiosis whereas asexual reproduction occurs only by a single parent and doesn't involve meiosis.

The species reproducing sexually has better chances of survival cause asexual reproduction results in offspring having the same properties whereas sexual reproduction results in variation among offsprings. Hence during adverse conditions, populations having variations along themselves have a better chance for survival.

Asexual reproduction does not involve genetic fusion while sexual reproduction involves fusion of male and female gametes to form a zygote.Species reproducing sexually have better chances of survival. This is because sexual reproduction gives rise to more variations which are essential for evolution as well as survival of species under unfavourable conditions.

That is the maindifference between sexual and asexual reproduction.Sexual reproductionjust means combining genetic material from two parents.Asexual reproductionproduces offspring genetically identical to theoneparent. The one producing sexually.Reason:- 1. During sexual reproduction,There might be errors in the DNA copying and lead to variations which might promote survival advantage2.In sexually reproducing organisms,natural selection might take place which may or may not give survival advantage.Like if you find it useful

nice answerrrrrrrrr.....

A reflex action is an unconscious, involuntary and instantaneous movement or response due to a stimuli. it does not require the involvement of the brain rather the use of nervous pathways known as reflex arcs.

An example of a reflex action is the instant drawing back of the arm from a hot object.

Here is how a reflex action takes place:Stimulus → receptor → sensory neurone → relay neurone → motor neurone → effector

A stimulus is the agent causing neurotransmission. Stimulus evokes the functional reaction of part of body or organ that is required.

An effector is any part of the body that produces the response. Examples of effectors are muscles that move the arm and glands that produce hormones.

the nerve pathway involved in a reflex action, including at its simplest a sensory nerve and a motor nerve with a synapse between.
