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.
Answer:
Alternate form of gene
Explanation:
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent.
The cell wall protects a plant cell by giving it protection and support.
The cell wall is made of cellulose which is a specialized sugar that helps give the wall structure and support to protect the inner part of the cell.
Answer:
The reduction of friction between the parietal and visceral surfaces of an internal cavity is the function of serous fluid.
Explanation:
Between the parietal layer and visceral layer of an internal cavity there is serous fluid that reduces the friction between these two surfaces and allows an easier movement of the parietal and visceral layers. The serous fluid is produced by serous glands that are in the parietal and visceral membrane.
