look at the photo, it wouldn't let me type it, sorry :-/
-DNA is the blueprint for proteins, which play many roles in the body. PROTEINS play many roles in the body and determine many traits. The section of DNA that codes for a specific trait is called a GENE. In fruit flies, straight wings are dominant and curly wings are recessive.
Oftentimes UV light can cause the genetic code of an organism to mutate, leading to a variety of errors, some of which are not compatible with life.
UV light is considered to be a mutagen. What this means is that the exposure of cells to UV light often leads directly to a mutation in the genetic code of that cell. This correlation has been studied extensively and shown to affect the nucleotides of DNA, which are:
- A base (adenine)
- T base (thymine)
- G base (guanine)
- C base (cytosine)
The exposure to UV light causes the base nucleotides in the DNA of an organism to oxidize. This oxidization causes the base pairs to form dimers. Most often the dimer formed is of a <u>thymine base</u>. This can be thought of as the fusion between two thymine bases, which will alter the frame in which DNA is read and <u>cause all sorts of abnormalities</u>.

Hello, BellaBouye205. Your answer would be Kurt Lewin. In the later years of his life, he devoted his time to studying small social groups. He claimed that groups change people's behaviorally as an individual. He also said that the small groups flourished greatly whenever they were preformed in a democratic way. I hope I helped!! Have a great evening.
Hey there,
Your correct answer to this question would be of that "<span>A statement of fact that is generally accepted to be true and universal because it has always been observed to be true."
</span>
Hope this helps you.
