Answer:
acquired characteristics.
those characteristics which are not determind by organism's chromosome are known as acquired characteristics.
these are environment influence or developed characteristics.
Explanation:
examples are lengthening of a body part which is frequently used. or the parts reduction which are not in use.
The Circumstance- PAcific Belt is also known as Ring of Fire, Circum- Pacific Belt or Pacific Ring of fire.
It is called this way because the term" fire" is associated with volcanos and "ring" because of its length.
This is the area in the basin of the Pacific ocean where many earthquakes and volcanic activity happen. The belt follows a chain of islands like the Philipines, Japan, etc.

The given question is incomplete, the complete question is:
A particular type of DNA damage involves purely chemical (non-enzymatic) degradation steps, like deamination, or depurination. Due to these, and other forms of DNA damage, cells employ a range of DNA repair mechanisms in order to maintain the integrity of the genetic code over millions of generations. Many eukaryotic cells have a specialized repair mechanism for the repair of G-T mismatches. This mismatch is repaired to form G=C (not A=T) base pair. This G-T mismatch repair mechanism occurs in addition to a more general system that repairs virtually all mismatches. Suggest a reason why cells might require a specialized system to repair G-T mismatches in this way.
Answer:
The repair of G-T mismatch is performed through the process called very short patch repair. The mismatch takes place because of the deamination of 5-methyl cytosine into thymine that occurs due to DNA mutation. The process of repair is performed with VSR endonuclease that eradicates the thymine on 5 prime end and then resynthesis of the patch is done with the assistance of DNA polymerase.
In case, if the repair does not take place it can result in transition mutation, that is, a kind of point mutation. As this repair is required to be very accurate, thus, the special VSR endonuclease is used for very short patch repair.
Answer:
The answer is letter A.
Explanation:
Increases peripheral resistance due to the narrow diameter of these vessels.
The blood flow trough the capillary beds reaches almost every cell in the body and is controlled to divert blood according to the body's needs. After oxygen is removed from the blood, the deoxygenated blood flows to the lungs, where it is reoxygenated and sent through veins back to the heart.
