Answer:
The mentioned case is an illustration of the missense mutation. A missense mutation is a kind of nonsynonymous substitution, that is, it is a mutation in which a variation in a solitary nucleotide leads to the formation of a codon, which encrypts for a distinct kind of amino acid.
When a missense mutation takes place within a DNA, a modification in one of the RNA codon sequences results at the time of transcription. This change in codon will ultimately result in the formation of a different amino acid, which gets presented within a protein at the time of translation. Like in the given case, a change in codon resulted in the substitution of the amino acid tyrosine with an amino acid cysteine.
Homozygous recessive is when an individual carries two identical copies of the recessive gene. An individual that is homozygous recessive for both traits will have the genotype, aabb.
When the body becomes dehydrated, a chemical signal is sent that causes nephrons in the kidneys to absorb more water and excrete more salts. This is an example of a <em>D Feedback loop</em>.
Answer: Option A and B.
Archaea and bacteria are prokaryote and reproduce by binary fission.
Explanation:
Archaea are grouped of single celled organisms that have no cell nuclei. They are prokaryotes and reproduce by binary fission. They were formally grouped as bacteria with the name archaeabacteria but the classification is outmolded. They are now renamed as archaea bacteria as they are closely related to eukaryotes.
Bacteria also are single celled, microscopic organisms. They are prokaryotes and they reproduce by binary fission. They have are number of shapes ranging from spheres to rods.
The answers is A). Plantas
