All Forms of Life Have a Common Ancestry Evolution Discussion

I don’t know how to handle this Biology question and need guidance.

 

1. Humans share 99% of their gene with chimpanzees, 90% with mice, 50% with fruit flies, and 37% with celery. Please explain the evolutionary significance of these data.

2. A population of Arctic fox is living in Alaska. Most of the foxes in this population have white fur, while a few have some brown coloring in their fur. Over a 100-year period the climate warms, resulting in much less snow and ice in the ecosystem where the fox population live. Not the majority of foxes int his population have brown coloring in their fur, while a few are completely white. Use what you have learned about natural selection to explain what happened. Include these terms in your explanation: beneficial trait, differential reproduction, selection pressure, evolution.

3. Use what you have learned about energy transfer in food chains and the second law of thermodynamics to explain why it is an environmentally good choice to eat a plant-based diet. Include the following terms in your answer: producer, herbivore, omnivore, trophic level, resources and energy.

4. Design a simple experiment. In your outline include:

Observation

Hypothesis

Dependent Variable

Independent Variable

Controlled Variables

Experiment Group

Methods/Procedure
