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.
Answer:
The correct answer is - vestibular.
Explanation:
Vestibular is the inner ear that helps in the sense of balance in vertebrates, that helps in the keeps an individual balanced. The vestibular system is the part of the inner ear that coordinate between movement with balance.
It is also helps in spatial orientation in an individual. It is something that helps in the sensing the change in orientation and movement that leads to balancing. Vinnie is standing in one leg with arms in the air, it is possible due to the vestibular sense that prevent falling.
Thus, the correct answer is - vestibular.
Answer:
The correct answer will be option-B
Explanation:
Three types of solution are formed based on the concentration of the solute which are:
1. High solute concentration- Hypertonic solution
2. Low solute concentration- Hypotonic solution
3. Equal solute concentration- Isotonic solution
When a cell contains a high amount of solute concentration and low concentration of water then it results in the generation of very high osmotic pressure.
If a cell is placed in an aquatic medium then due to high osmotic potential, the water will enter the cell which will lead to the rupture of the cell membrane. This process of rupture of the cell membrane is known as the plasmolysis.
Since the cell rupture due to the generation of very high osmotic potential, therefore, is the correct answer.
The jet stream brings down colder air from the north into the southern regions of the United States so B . southeast I think.
