Natural selection is the process that result in the adaptation of an organism to environment by means of selectively reproducing changes in its genotype, or genetic constitution. It is the a key mechanism of evolution. Charles Darwin popularised the term "natural selection" contrasting it with artificial selection, which is intentional, whereas natural selection is not.
To make it simple, let's have a group of beetle composing of green and some are brown as an example. here, there is a variation in traits. Since the environment could not support continuous population growth, not all species can reproduce to their full potential. Green beetles can easily be eaten by other species like birds compared to brown beetles. The surviving brown beetles will then generate brown offsprings because their trait has a genetic basis. Since more brown beetles survive and becomes more common in the population, the process continues until all individuals will eventually be brown. so basically, if you have variation, differential reproduction, and heredity, you will have evolution by natural selection as an outcome.
The reason the flower is pink, is mainly because when you mix a light color ( in this case a a white flower) in with a red, it creates a pink color. In others words, when you mix white and red, it creates pink. Hope this helped!
Explanation:
option A is the correct one.
Answer:
Test a hypothesis
Explanation:
An experiment is done to test a hypothesis. An experiment can either prove or disprove a hypothesis. The experiment should be designed in a way that it can be repeated for validity to ensure that the results that come out of it holds true each time.
A hypothesis is made before the experiment is done. Developing data is done through interpretation of the results of an experiment. A conclusion is formed through analysis of the data obtained from an experiment.
