Explain how you decided which illustration represents the most recent rock pocket mouse population and why you positioned the others in the order that you did.
Adaptation is the process of adjusting to the altered environment for survival. The population of the dark mouse will increase while that of the light coloured mouse will decrease.
What are adaptation and fitness?Adaptation is the biological process in which the organisms acclimates to the altered situation so that they can reproduce and survive. The naturally selected species with better trait quality will be able to survive and one with the unfavourable trait will be eliminated.
The fur colour of the mouse affects the fitness and the survival rate of the mouse population as the change in the fur colour was for the adaptation to the altered conditions.
The transformed mouse species have better chances of survival as they will blend with the dark colour of the rock surfaces compared to the light coloured mouse. The light coloured mice can be easily spotted by their predators.
The dark coloured mouse population will increase over time as they will adapt and only fit organisms will be able to survive.
Therefore, the dark coloured mice will increase and light coloured will decrease.

a food that contains only 7 amino acids is?
Answer and Explanation:
Certain foods that are incomplete proteins do not contain all of the necessary amino acids that would be helpful.
Incomplete protein foods are anywhere from seeds, nuts, and whole grains. Whole grains consist of whole wheat bread and brown rice. Not only that, but even types of beans, peas and lentils (which tend to be part of the legume family).
Typically, incomplete proteins are harder for the body to digest and brake down. But don't be fooled, not all complete proteins are easy to be broken down either.
