Answer:
Explanation: In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. A concentration gradient exists for these molecules, so they have the potential to diffuse into or out of, the cell by moving down it.
Answer: Mutations in genetic code occurs when DNA is being duplicated.Any changes in the base pairs leads to mutations by trasition or transversion. Change in amino acid leads to change in sequence and thus, mutation. This si carried on to new generation, if it takes place in germ cells.

Answer:
Wildfire
Explanation:
The wildfires are one very devastating occurrence that can appear both naturally and be caused by humans. Naturally these fires occur because of high temperatures and drought, and because of thunders. When they occur, they spread out very quickly and it is an uncontrolled fire.

While the wildfires are very destructive, there's also a positive from them, as they leave behind lot of ashes, and the ashes fertilize the soil, providing the basis for the growth of new vegetation.
Answer:
Species with larger population sizes have more noncoding DNA.
Explanation:
The statement that most non-coding DNA is deleterious contradicts the fact that Species with larger population sizes have more noncoding DNA. Had the non coding been deleterious , its proportion in species with larger population would have been less but the fact that species with larger population sizes have more noncoding DNA contradicts it.
Answer:
wind and solar energy rely on weather to generate power unlike fossil fuels
