kondor19780726 [428]

Answer and Explanation:

A gene is a section of DNA. The change in the sequence of the DNA is known as mutation.  Mutation always changes the sequence of the DNA. Sunlight can cause mutation. Sunlight produces structures named thymine dimers. Thymine dimers produce twist in the shape of DNA. These twists make DNA hard to copy, which can lead to mutation. It is essential to use sunscreen to block UVA and UVB rays to prevent thymine dimers from emerging in our cells. The US Food and Drug Agency recommends an SPF (sun protection factor) to defend against skin aging and skin cancer. X-ray radiation is a form used in x-rays. The energy level of the X-ray radiation is very high that can produce free radicals. Free radicals can steal electrons from DNA that can cause mutation. By using medical images, we can decrease exposure to X-rays. Less exposure to X-rays prevents mutation and also prevents the production of gene protein in other body parts.

postnew [5]
The appropriate answer is B. Throughfall. These nutrients are transported via the process of throughfall where rain flows from leaves to the ground. Rainforests receive high annual rainfall. The leaves are also designed to funnel water to the ground soon after a shower. Leaves are equipped with drip tips to allow water to roll of leaves easily. Any particles deposited on leaves are going to be washed to the forest floor by frequent rainfall that occurs here.
