The answer is; C
Testosterone is regarded as the male hormone and responsible for male attributes such as high muscle and bone mass. It is produced by the Leydig cells of the testes This hormone is responsible for the formation of sperm in the male gonads. Therefore the hormone ensures male fertility.
Answer:
The muscle action can be determined by:
* Prime Movers and antagonist: Prime movers are also called the agonist, it is the muscle that provides the force that drives the action. Regarding to the antagonist muscle, it is the opposite to a prime mover as it provides resistance or reverse in a given movement. They are paired up on opposite sides of a joint.
* Synergists: There are one (or more) synergists involved in an action, the are muscles that help the prime mover when it is playing its role.
* Stabilizers: Their fuction is to keep bones immobile when it is needed. For example, the muscle of your back, they are stabilizers when the keep your posture sturdy.
Mistakes during mitosis lead to the production of daughter cells with too many or too few chromosomes, a feature known as aneuploidy. Nearly all aneuploidies that arise due to mistakes in meiosis or during early embryonic development are lethal, with the notable exception of trisomy 21 in humans.
<span> Chromosomal banding pattern is the pattern of colors formed when the chromosome is exposed to certain specific dyes.
These dyes do a color reaction with a special repetitive sequence of base pairs.
When the normal pattern is not obtained
there may be two reasons
1. Chromosomal injury
2. Chromosomal aberration.
In injury certain part is either deleted or shifted to somewhere else
in aberration chromosome is normal but its sequence is got changed.
So its certain that is has got great diagnostic value.
But it fails
in case of point mutation or certain others.
This banding pattern is also helpful in preliminary diagnosis of a suspect in any crime but most of the judiciaries do not assure of its results. </span>
