As a human being, I actively incorporate the three R's into my lifestyle in various ways.

Additionally, I try to reuse items whenever possible, such as repurposing glass jars for storage or using old t-shirts as cleaning rags. By practicing the three R's, I am able to reduce my carbon footprint and contribute to a more sustainable future.
In three short sentences, describe natural selection and its function/purpose.
Natural selection is the process by which organisms that are better adapted to their environment are more likely to survive and reproduce. Over time, this leads to the evolution of new species with traits that are beneficial for survival. Its function/purpose is to ensure that species are able to adapt to changes in their environment and continue to thrive.
Why would green feathers be considered an advantageous trait in this environment. Write 2-3 sentences on this.
Green feathers could be considered an advantageous trait in an environment with lots of vegetation or foliage because the green color would provide camouflage. This would make it easier for the bird to hide from predators or prey, increasing its chances of survival. Additionally, if the green feathers were reflective, they could also potentially attract a mate.
What fur color would you expect to see if climate change had caused SHORTER winter season and a longer summer? Why? Use 2-3 sentences.
If climate change had caused a shorter winter season and a longer summer, I would expect to see lighter fur colors in animals that live in the affected areas. This is because a lighter color would reflect more sunlight and help keep the animal cool in the longer, hotter summer months, while not providing as much insulation in the shorter, milder winter months. As a result, natural selection would favor animals with lighter fur in these conditions.
Explain why there is such a wide variation for the trait of skin tone in humans. Use 2-3 sentences.
There is a wide variation for the trait of skin tone in humans due to the role of evolution and natural selection. Skin tone is linked to the amount of melanin produced by the body, which helps to protect against harmful UV radiation. As humans migrated to different parts of the world with varying levels of sun exposure, natural selection favored individuals with skin tones that were better adapted to their environment, leading to the development of a wide range of skin tones.
