Answer:
b. skin from mouse 2
Explanation:
According to this question, a mice skin transplant is being conducted. Four mice labelled Mouse 1, Mouse 2, Mouse 3 and Mouse 4 are used for this experiment. A small patch of skin from mouse 2 (the donor) was transplanted onto mouse 1 (the recipient), however, it was eventually rejected by the recipient (mouse 1).
This transplant rejection is due to the fact that the recipient's immune system identifies the tansplanted skin as foreign, hence, begins to attack it, leading to the skin's necrosis or death. Based on this, the same transplant rejection will occur if skin patches from mouse 3 and 4 are used.
However, the immune system of mouse 1, which is the recipient, will identify skin patches from MOUSE 2 as less foreign than any other skin from other mice. This is because skin from that mouse has been used before, hence, the recipient's immune recognizes it when a follow-up transplant is conducted. This makes a follow-up transplant from MOUSE 2 be the least likely to be rejected.
The correct answer is letter (B) Asexually. <span>An organism has two types of cells: diploid somatic cells and haploid gametes. Diploid somatic cells and haploid gametes reproduce using mitosis. During mitosis, it creates an identical copy of the cell. They are non-sex cells. They are the cells that make up the sex organs, muscles, skins, hair, etc.</span>

Amino acids
Explanation:
This is because they form into long chains in order to form protein
Answer: Option A
Explanation:
A tunicate is marine invertebrate animal which is a part of chordates. They have notochords and dorsal nerve chord. The subphylum of the organism is called as Urochordata.
The adult urochordates lack notochord but the larval stage of the urochordates have notochord. This is because it helps in swimming of the organism which is required only at the larval stage.
The adult stage of the tunicates is sessile and they do not swim so they do not require notochord.
Because they have more underlying factors such as (straight) brown hair or (curly) blonde hair from different parents. A punnet square would be too big and confusing if we considered all the factors that came from the parents.
