Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.

Field mice in beach mice are closely related species. The Field mice are various shades of brown in the beach mice or later 10 a
wariber [46]

Answer:

The process of natural selection is acting on <u>Field mouse individuals</u> where as evolution is occurring on <u>Field Mouse population. </u>

Explanation:

As the problem shows, the field mice are the ones that natural selection is acting on, but only the ligher shade ones. Because the lighter shade individuals are more likely to survive in the beach because they blend with the environment.

Evolution occurred on the field mouse population because if you read the script in the end, they were able to successfully reproduce. This means that they evolved in such a way that they were able to survive in their new environment. (most likely carrying on the trait of light-colored fur)

Natural selection acts on traits, phenotypic traits, favorable to the environment. Evolution occurred because of the natural selection, because the favored trait enabled the organism to adapt to the environment.

What are the chances that a cross between a black chicken and white chicken will result in blue offspring?
Shkiper50 [21]

The correct answer is 100%

This is because Back and white are both incomplete dominant traits. When you cross these together, all (100%) of the offspring will be heterozygous blue.

I just took the test on USATestPrep, so I guarantee you that is correct!

Have a great day! :)
