Answer:
a) 28 cases
b) 3 cases
Explanation:
a) From the table of genetic codes, there are 28 codons that specify more than one amino acid assuming only the first two nucleotides are considered. In these cases, one cannot outrightly specify the amino acid the genetic codes are coding for without knowing the last nucleotide of the codes. <em>For example, UU can be for Phenylalanine or Leucine, CA can be for Histidine or Glutamine, etc. </em>
b) From the table of genetic codes, the first two nucleotides of Arginine can be either of CG or AG, that of Serine can be either of UC or AG while that Leucine can be either of CU or UU. Only in these <u>3 cases</u> would one fail to know which are the first two nucleotides assuming the name of the amino acids are given.

The answer to this question is summer I know this for a fact cause I took biology last year your welcome
Answer:
A - Hypothalamus and Antidiuretic Hormones
Explanation:
Whenever their is a sudden change in the fluid level in the bodyb, either the blood, sugar, etc., the osmoreceptors, a special group of cells within the hypothalamus part of the brain, will detect this.
Thereafter, a signal is sent to the posterior pituitary gland to release the antidiuretic hormones (ADH), whose job is to maintain the fluid level by causing an increase in water reabsorption into the body through the expansion of the epithelial cells of the kidney.
Primary function of the carbon cycle is to "recycle carbon throughout the biosphere, which includes the atmosphere" Hope this is what you needed!
