"maintaining a steady state internal environment, despite a changing external environment, is called homeostasis"
<span>Homeostasis is any self-regulating process by which biological systems tend to maintain internal stability with the tendency to resist external changes. Homeostasis involves negative and positive feedback loops.</span> <span>Homeostasis depends on the ability of the body to detect (via sensors) and oppose these changes. From sensors signals are sent to the control center<span> in the brain, and then after processing the information the </span>effectors are activated.</span>
I believe the answer is: The dark colored moths will experience disruptive selection
The bird prey on moth and possibly identify the moth by visual sense. The moth has two type of color: dark and light. The trees in the area is more light coloured so the black moth will be identified easier as their color is more contrast to the tree. As the dark moth easier to identify, they will be predated more and their population will be reduced. When a trait has advantage than the other, disruptive selection happens.
The correct option is this: HAS THE CLAIM BEEN TESTED NUMEROUS TIMES BY MORE THAN ONE SCIENTISTS.
For a claim to be accepted has been valid in the science world, it must have been tested several times by many scientists who obtain the same results. Having a uniform result about a phenomenon is usually considered an important factor when examining the validity of a claim.
