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.
<span>The answer is: they are not the right ways to lose weight.
</span><span>All of these methods are not healthy because they don't have enough essencial nutrients, they</span> contain chemicals/ irregular ingredients and makes our metabolism slow down to save energy.
They can make people lose weight because they are cutting drastically their calorie intake but it can't be maintained forever. Most likely people will regain the weight lost after ending this diets.
Answer:
1) Mechanical Weathering, 2) Chemical, 3) Physical
Explanation:
Only one strand will be transcribed and the other servers as a coding stand. ... Without it, the single strand DNA with exposed nitrogenous bases is very unstable so two strands actually stabilise the structure.
Answer:
They go through many developmental changes. ... Studies by independent researchers show a link between pesticides and frog deformities.
