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.

Rina8888 [55]

Answer:

Humans have destroyed and modified various locations, such as forests, jungles, oceans. They begin to modify an environment in order to build new infrastructures, like buildings, factories, or even communities.

Explanation:

The reason for this is because they want to get as much resources for economic purposes, like for example mines, touristic places, factories. At first, this interaction affects the environment more, because of the loss of species or resources due to the human activity. Then, after this, it will affect the human, because of the lack of resources and global contamination caused by the environment being destroyed or modified.
