Answer:
c. accidental removal of the parathyroid glands during surgery
Explanation:
Parathyroid gland is found closely situated at the back of the thyroid gland in the human neck region. Regulation of serum calcium levels in the body is a major function of the parathyroid gland through the secretion of a hormone called parathyroid hormone or parathormone.
During the surgery conducted to remove the thyroid gland, it is very likely that the parathyroid glands were accidentally damaged or removed. This most likely led to the non--secretion of parathormone, which is responsible for secretion of calcium in the body, when calcium levels drop.
Answer:
The protein would be incorrect and the protein might not function.
Explanation:
We know that introns carry information but introns not only carry information to build a protein. They have to be removed for the mRNA to encode a protein with the right protein sequence.
If the spliceosome fails to remove an intron, an mRNA with extra "junk" will be created in it. As a result, a wrong protein will be created during translation.
If a wrong protein sequence is created, it will hamper the whole translation process. The protein won't function properly.
Answer:
The best example of environmental influence that would most likely result in natural selection is that a food resource disappears in a pond, and some frogs in a population can eat the remaining food resource, while others cannot.
Explanation:
Among the environmental factors that can influence natural selection at a given time is the availability of food. Natural selection, from the point of view of evolution, is influenced by adverse environmental conditions, being food shortage one of them.
In conditions of food shortage in a pond, as in the example of the frog population, only the most apt will be able to take advantage of nutritional resources, while the less apt will not be able to survive. The ability to survive with little food available becomes an inherited trait that will be passed on to future generations.
In any case, tolerance to adverse conditions becomes adaptation, which translates into survival and reproductive success.

Cirrhosis of the liver is a disease that effects the function of the liver. the liver has a function to clean out and detoxify the body. If at that point the liver cannot clean out the toxins you either have dialysis to help clean out the toxins in the liver. it causes the kidneys not to function correctly and you may need a kidney transplant.
When the effects of genes add up to make the phenotype, they are called additive genes.
