A, because every sex cell is genetically different from on another
Fossils can provide the time a species existed through carbon-14 dating, and can also show structures within the species that are similar to other organisms on earth today or other organisms before/slightly after that fossils existence.
Answer:
The electrical and diffusion potentials for K+ will be equal in magnitude and opposite in direction.
Explanation:
The cell potential may be defined as the potential difference between the inside of the cell and outside the cell. This difference is important for the transmission of nerve impulse.
The equilibrium condition may be defined as the condition at which the exit and the entrance of the ions will be equal. As the information in the question, Only potassium ions will move inward and outward of the cell. The potassium ions will move in opposite direction since the equilibrium has been reached.
Thus, the correct answer is option (D).
Answer:
A) B cells produce plasma cells, which secrete antibodies into the blood
Explanation:
There are two types of lymphocytes present in blood. These are namely, B lymphocytes and T lymphocytes. The B lymphocytes are activated with help of T lymphocytes. The activated B cells divide and produce a large number of cells that differentiate into the plasma cells. These plasma cells finally produce antibodies against specific antigens.
