Suppose Gene 1 produces a protein involved in the development of the eye. In the simulation, what are two ways that you can prev
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.

How do the nervous system and endocrine system differ in regards to managing homeostasis?
Citrus2011 [14]
Hello friend!!
The biggest difference between the two is that the nervous system uses electrical impulses to send signals through neurons, whereas the hormonal system uses chemical messengers transported into blood plasma to target cells. 
Transmission by the nervous system is short-lived but quick, whereas transmission by the hormonal system is long-lasting but takes much longer. Hene, communication is faster when using the nervous system. 
In the nervous system, responses are localised - whereas in the hormonal system, they are widespread. Responses are often permanent in the hormonal system, but temporary and reversible in the nervous system.

This question is based on an opinion and should not be used as a factual data resource. GMO's acceptance should continue to be limited because of the growing amount of heath problems that can be related to Genetic Modification in plants and animals.
