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.
The Earth and Moon compare in terms of gravitational force as Earth's gravitational force is stronger than the Moon's.
Option A
<u>Explanation:</u>
According to universal law of gravity, the gravitational force is the attractive force between two objects separated by a distance. The magnitude of gravitational force is directly proportional to the product of masses of the objects and inversely proportional to the square of the distances between them.
In this case, the gravitational force acting on us due to Earth will be considered due to the mass of Earth as the mass of Earth is very large compared to our mass.
So as the mass of the Earth is greater than the mass of the moon, so the gravitational force of Earth will be stronger than that of Moon.
Answer:
"The most significant effect of population growth in Europe from 1700 to 1800 was urbanization and the creation of large cities which was marked by poverty, crime, and poor sanitation.” Historians have identified several causes for the Industrial Revolution, including: the emergence of capitalism, European imperialism, efforts to mine coal, and the effects of the Agricultural Revolution.
