Answer: Most of the beetles will be brown because they have a higher likelihood of reaching reproductive age.
Natural selection is the process of selection by nature in which an individual organism exhibiting more favorable phenotypic characteristics has more chances of survival and reproduction in it's corresponding environment.
In the new environment, brown beetles can camouflage themselves from predators better than the green beetles and blue beetles can. This is because of the fact that brown color of beetle is a better phenotypic trait which favors the survival of brown beetles over green and blue color. Therefore, the survived brown beetles will reproduce and grow in number.
Good coronary circulation nourishes the heart and reduces the risk of a heart attack. Coronary arteries supply blood to the myocardium and other components of the heart. They originate from the left side of the heart at the base of the aorta. The heart muscles needs oxygen-rich blood to be able to carry out its functions.
This was Lamarck's idea. Here's an example: Suppose giraffes originally had short necks that they stretched to reach high-up leaves in the trees. This continuous stretching of the neck was passed onto offspring, who as a result had slightly longer necks. This continued for multiple generations until we get today's long-necked giraffe. Lamarck was on to something (that something being evolution by natural selection, which Darwin discovered), but his theory wasn't completely correct since organisms can only pass on genes (segments of DNA that code for a characteristic or function) to their offspring. Since "stretching" would not code into DNA, it wouldn't be passed onto offspring, proving Lamarck's theory incorrect.
The correct answer is B.
The humans forearm is much like a bat wing, because all of our tendons and liniments. Although we do not use the structures in the same ways, they are alike.
