In a point mutation, one single base nucleotide (A, C, T or G) is replaced by a different one. This results in the change of one amino acid in the protein. (A minor change that may or may not affect the overall function of the protein) .a frameshift mutation, one or more base nucleotides are inserted or deleted from the sequence. This shifts the 3 basepair codons resulting in a change in the amino acid sequence that is coded. An entirely different protein (usually nonfunctional) is coded.
Answer:
The correct answer is B. In the human eye, the greatest amount of refraction occurs when the light passes from the air into the cornea.
Explanation:
The ocular refraction refers to the refraction that occurs in the light coming from the objects when crossing the different parts of the eye, causing the images to concentrate on the retina.
When the light rays, after crossing the cornea and the lens, are projected on the retina at a single point creating a clear image that is transmitted to the brain for processing, we talk about normal refraction.
Answer:
a. ischemic conditions.
Explanation:
Hello,
In this case, considering that acute tubular necrosis (ATN) has been widely acknowledged as a harmful medical condition showing off the death of tubular epithelial cells that give the form to the renal tubules of the kidneys; it presents with acute kidney injury. Thus, common causes of ATN include low blood pressure and use of nephrotoxic drugs which is more technically known as a. ischemic conditions in which the blood flow is very weak.

Some mutations have a positive effect on the organism in which they occur. They are called beneficial mutations. ... They increase an organism's changes of surviving or reproducing, so they are likely to become more common over time. There are several well-known examples of beneficial mutations.
