A normal range in adults is generally considered to be 4.35 to 5.65 million red blood cells per microliter (mcL) of blood for men and 3.92 to 5.13 million red blood cells per mcL of blood for women. In children, the threshold for high red blood cell count varies with age and sex.
The answer is c. cluster.The most common type of distribution pattern in nature is clustered. That is because resources are patchily distributed in the environment. So, if resources are rare, or due to social factors, individuals would cluster together in the area where these factors are favorable.Random distribution is the least common type of distribution pattern and it is found in homogeneous environments, which are very rare.Regular distribution is the result of the competition for a resource or direct social interactions between individuals within the population, such as territoriality.

The nuclear membrane includes an array of small holes or pores that permit the passage of certain materials such as nucleic acids and proteins, between the nucleus and the cytoplasm .
Answer:
B, G , E, F.
Explanation:
Hemoglobin is known to be a tetrameric hemeprotein, which is found in the erythrocytes where it binds with oxygen,and then the bound oxygen is transported to parts of the body.
Myoglobin is a monomeric protein that is found in the muscle tissue. Its function is that, it serves as intracellular storage site for oxygen.
It should be understood that, both hemoglobin and myoglobin are hemeproteins with physiological importance of having the ability of binding molecular oxygen.
In this case, it is also known that, the two, that is hemoglobin and myoglobin have a prosthetic group called heme, which is described or known to be a tightly bond, specifically a non-polypeptide unit which is required for biological function of some protein.
