Answer:
The correct answer is diaphragm.
Explanation:
One of the barrier methods of controlling birth is the diaphragm. It is abstemiously efficient, with a one-year failure rate of approximately 12 percent with the typical application. It is positioned over the cervix with spermicide prior to having sex and is left in position for about 6 hours post-sex.
It is a rubber barrier that holds the spermicide against the cervix. The spring in the diaphragm's rim produces a seal against the walls of the vagina. The diaphragm covers the cervix and physically inhibits sperm from getting inside the uterus via the internal orifice of the uterus. Basically, the diaphragm has an application with spermicide, and it is broadly considered that the spermicide substantially enhances the efficacy of the diaphragm.
If the Na+ voltage-gated channels in a muscle cell open, the Na (sodium) ions rush inside the muscle cell and makes the cell more positive as Na ions carry positive charge on it. Due to the entry of positively charged ions inside the cell, the cell becomes less negative and more positive. This is called depolarization of cell.
The correct answer is - a. It will reduce genetic diversity.
The pumas that live in Florida, also known as the Florida Panthers, will have a much reduced genetic diversity. The reason for this is that the population is very small. It also lives in the same area, where the living conditions are the same. The genetic pool is very small, and the breeding is going on between individuals that have the same traits, and are also relatively closely related, as the mating occurs between the second or third generation that came out form the same parents. That will result in a very reduced genetic diversity, so the Florida Panther will remain the same if the conditions do not change drastically, or these an invasion of pumas from the west into their territory.
