They become their own prey by feeding on plants or other producers.

Explain how you choose which picture best depicts the most recent rock pocket mouse population and why you arranged the other illustrations in the order that you did. Also explain why you positioned the other illustrations in the order that you did?

Because the environment favors dark mice over light mice over time, we were hoping to see a progressive decline in the number of light-colored mice while simultaneously seeing a gradual rise in the number of dark-colored mice.

Why are there mice that are lighter in color and mice that are darker in color?

Because diverse mutations in the DNA led to the development of distinct phenotypes.

-white mice are the most prevalent kind to be found in the sandy desert.
– The presence of dark mice is most prevalent on the lava.

If the environment favors a specific hue of fur, then having that fur color might be a benefit.

Yes, it is simpler for the darker-colored mouse to blend in with its surroundings when it is in a darker setting, and the same is true for the other way around.

birds of prey eat visible predators like foxes, coyotes, and rattlesnakes, as well as owls and hawks.

Give an explanation as to why the color of a rock pocket mouse affects its overall fitness. Keep in mind that the capacity of an organism to survive in its environment and create offspring is what defines “fitness” for that organism.

It makes it easier for them to blend in with their surroundings, which in turn improves their chances of survival.

Defend your position on the existence of mice with black fur in site A. Why did this particular phenotype not become more prevalent across the population?

Because site A was composed entirely of rocks with lighter tones, there was never going to be an accumulation of those with deeper tones.

Because Location B was suddenly blanketed with dark-colored volcanic rock, mice with darker fur had an advantage over mice with lighter fur in the new habitat.

a description of the factors that led to the alterations

Because Location B was suddenly blanketed with dark-colored volcanic rock, mice with darker fur had an advantage over mice with lighter fur in the new habitat.

– a forecast that outlines the demographic characteristics of the world’s population one hundred years from now -o Make your forecast based on patterns that emerge from the data you’ve gathered and structured. It is safe to presume that the circumstances of the environment have not changed during the last century.

Because more of their children lived to breed and pass on their genes, including the genes for fur color, over time, dark-colored mice became more prevalent at site B. This is because the genes for fur color are inherited.

In one hundred years, the mouse population at place B will probably be dominated by mice with darker fur, most certainly. There is a possibility that some of the mutants will have lighter skin.

Explain why mutation is a random process, but natural selection is not random by using the evidence and what you have studied about evolution to support your argument.

The fact that the dark-colored mutation was found in habitats that were devoid of any volcanic activity (indicated by location A) is evidence that the mutation occurred by chance. However, once there was a selective advantage for the dark-colored phenotype, it became more prevalent (as illustrated by position B), which suggests that selection is not random.

Which of these words best explains the structure of a dark pigment found in organisms?

melanin

1. In what capacities does the pocket mouse contribute to the food chain of the desert?

Starting with a single plant is the first step in a food chain. This might be a plant that thrives in arid environments, like mesquite, and would thus perform well in the desert. It’s possible that a pocket mouse may come along and eat the seeds off the plant, but then a snake like a sidewinder will come along and devour the mouse.

2. What do rock pocket mice do?

The rock pocket mouse is a nocturnal rodent that is medium-sized (length between 12 and 18 centimeters and weight between 12 and 18 grams) and lives mostly on rocky outcrops in the deserts of the southwestern United States and Mexico. Its primary source of nutrition is plant seeds, and it digs little tunnels in the dirt next to or beneath rocks in order to conceal itself from owls, who are its most common adversaries.
