1. Populations can have variety, despite being made up of the same species. If a population has different expressed traits, this

can be due to different inherited alleles. The frogs below are the same species, but they have different shades of green based on their inherited alleles. In a particular environment, lighter green frogs are easier to see by predators. Explain how natural selection could lead to a change in the freq
uency of certain alleles present in the frogs over time.4

Natural Selection proposes that organisms that are better adapted to their environment are able to survive and reproduce.

Even though these frogs are the same species, their shades of green is what helps them to survive in their habitat. In this case, frogs with a lighter shade of green are able to be seen by predators easier, whereas frogs with darker shades are able to blend in (camouflage) more with their surroundings. After a period of time, due to them being easily seen, lighter-shaded green frogs will die off.

To anseer your question, natural selection would have a gradual affect on the frequency of the alleles. Lighter-green allele frequencies would eventually cut off, and darker-green allele frequencies will increase.

Hopefully the following image will help:
As seen in the image, (please forgive the quality, as I had drawn this on some random kids drawing site on the internet...) you can see the affects of natural selection on the allele frequencies. The brighter-green shades gradually decrease over time, as the darker shades increase.

Hope you find this helpful.

What is meant by transpiration is a necessaru evil?
3241004551 [841]
In plants, transpiration is a process which is inevitable but potentially harmful, because it can cause loss of water. Loss of water can lead to wilting and eventual death of the plant. Even a little stress can interfere with the plant's growth process. 

But, at the same time, transpiration is necessary because of a number of reasons - the transpiration stream aids the processes of mineral absorption, water absorption, energy exchange, helps provide the plant with optimum turgidity, it helps the exchange of gases and so on.

Eggs have species specific receptors on their outer surfaces to which sperm must attach if fertilization is to occur
mafiozo [28]
The  question is; would a drug that binds irreversibly to these receptors be an effective contraceptive in mammals?, the answer is;Yes; because if the receptors are blocked the sperms will not be able to penetrate the zonal pellucida of the egg.  Contraceptives prevents pregnancy by interfering with the normal process of ovulation, fertilization, and implantation.

A student wants to perform an experiment to test the effect of different colored lights on the growth of basil plants. She sets
Elena-2011 [213]

Answer:

light is the independent variable, height of the plant is the dependent variable. Dependent is the effect that based on the independent.

Explanation:

lets break it down. 1) you want to know the effect of something you apply from one thing to another. Let say, if you grow your plants under the sunlight, the plants grow taller. In this case, the sunshine is the independent variable whereas the height of the plant/how tall it can grow is the dependent variable. 2)NOW, before i give the answer. The design of the question is not good for high school students. i think your teacher thinks "light" is the independent variable. 3)However, the question contains confounding variables in it because different lights might produce different effects to the height of the plants. If you want to test if plants are exposed to light grows taller than plants do not expose to light, then you should have all the lights are the same. 4) So, all the plants should be exposed to one certain light to avoid confounding. Confounding means that either red light and sunlight are both produce the same effect whereas the other colors do not help the plants to grow taller. 5)Your teacher should test one light at a time. So, if he is testing with all different colors of light, then light is the independent variable, and height of the plant is the dependent variable.
