The answer is B). Because Centrioles play role in Mitosis. Prokaryotes don't divide by Mitosis. They divide by binary fission.
Answer: False
Explanation:
Hemoglobin can be defined as red protein that transports oxygen to various parts of the body according to its need.
It does not transports the same amount of oxygen to all the tissues. Some tissues of the body might require more more oxygen and some cells might require less amount of oxygen.
It depends on the state of activity. It transports more oxygen to the tissue that require it the most.
Example: The skeletal muscles of the body require more oxygen and it can be more than 80% .
Hence, the given statement is false and hemoglobin does not releases the same amount of oxygen to each and every tissue of the body.
When all forces acting on the object are in the same direction
Answer:
A, viruses can only infect a range of cells
Answer:
Simple Diffusion.
Explanation:
The plasma membrane is known as the selectively permeable membrane as they allow the movements of some selected particles only. The movement are facilitated diffusion, active transport and passive transport.
Water molecules are polar in nature. They can pass through the plasma membrane from its region of the higher concentration towards its region of the lower concentration. They move directly through the simple diffusion and does not require any protein or energy molecule to pass through them.
Thus, the answer is simple diffusion.
