Explanation:
Genetic variation refers to the difference in the genetic material of the offspring compared to their parent. The changes in gene occur as a result of the natural selection pressure and the new combination of sequences is formed in the gene in individuals.
The individuals with variation are then selected by nature based on the basis of how much these genetic variations prove beneficial:
1. The new combination of sequence could allow the population to adapt to the new environment
2. The new combination can allow the population to survive and when the population survives then the reproduction rate of population increases.
Mushu is a definitely answer
The question, which is what the researcher wants to know, could be the following: <em>What is the effect of the change in </em><em>available</em><em> </em><em>food</em><em> </em><em>sources</em><em> on the</em><em> birds' feeding habits</em><em>?</em>
<h3>What are the steps of the scientific method?</h3>
There are different steps to follow in a scientific method
- Definition and problem statement. The question for which there is no answer yet. A question the investigator wants to answer.
- Goal specification. The goal is what the investigator wants to know.
- Hypothesis formulation. The researcher hypothesizes in order to predict what is going on or what is expected to occur.
- Experiment. Different variables influencing the project are considered. Data collection and analysis stages. This step involves testing the observations.
- Discussion and hypothesis verification. This step involves the deriving of the working hypothesis.
In the exposed example, the experiment involves watching the birds feed, and then removing fruit to simulate an environmental change.
The independent variable here is the food source availability.
The dependent variable is the birds' response to the change.
The question, which is what the researcher wants to know, could be as follows,
What is the effect of the change in available food sources on the birds' feeding habits?

The correct answer is telescopic.
A scope is also known as a telescopic sight refers to an optical sighting apparatus, which is based on a refracting telescope. They are incorporated with a certain pattern of graphic image mounted in an optically suitable alignment in their optical system to produce a precise focusing point.
The telescopic sights are utilized with all the kinds of systems, which need precision focusing, however, they are most generally used on firearms, mainly the rifles.
The answer is B , because your stress decreasing can not cause a disorder
