Answer:
The functional unit of a muscle cell is known as a "sarcomere" which covers the distance between the two Z-lines.
The sarcomere consists of A-zone which contains both thick and thin filaments, H-zone which contains only thick filaments and I band which contains only thin filaments.
During muscle contraction, thick and thin myofibrils slide over each other due to which the distance between two z-line get reduced.
The H and I zone gets shortened but A zone does not shorten but come close to other A- bands and disappears.
Answer:
Meiosis
Explanation:
In a process of meiosis a sing cell divides twice to produce four daughter cells which contains half the amount of. genetic information These cells are sex cells. These four daughter cells consists of half the number of chromosomes of the parent so they are haploid. This is the reason in maple tree the chromosome decreased from 52 to 26.
