It tells about antigens. If blood has Type A antigen, or Type B antigen, or both of them, or neither of them.
Answer:
Total 495 liters of natural oil are needed.
Explanation:
It is given that Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 5 liters of natural oil for every 3 liters of synthetic oil.
It means the ratio of natural oil and synthetic oil is
Let in order to make 792 liters of Petrolyn oil he needs x liters of natural oil.
It means the ratio of natural oil and synthetic oil is
Equate both ratios,

On cross multiplication we get


Divide both sides by 8.


Therefore total 495 liters of natural oil are needed.
Only 200 out of 2 000, 000 sperm cells reach the ovum. And only one (in exception to very rare cases of two) sperm cells actually participate in the process of fertilization. In comparison, an average female only produces 400 of egg cells during their lifetime, but the eggs cells are significantly larger than sperm cells.
Answer:
No cellular energy is needed in the Passive transport.
Explanation:
A movement of atomic molecules and ions throughout the cell membrane is known as passive transport. In this transportation of molecules no cellular energy is used.
As this movement is influenced by the tendency to grow as entropy, the energy is not in need unlike the active transport. Its rate depends on the permeability of cell membrane. There are four types of passive transport- facilitated diffusion, simple diffusion osmosis or filtration.
