<span>The average human red blood cell is roughly 6 to 8 micrometers wide. The width of a pin is this problem is defined as 1000 micrometers. Assuming we use the smallest size of a blood cell, then we divide 1000 by 6, and we find that roughly 166.66 (or 166 if you are rounding down) red blood cells will fit.</span>

attashe74 [19]

Answer:

The correct answer is "each of the MHC genes has a large number of alleles, but each individual only inherits two for each gene".

Explanation:

In normal conditions, an individual has only two different alleles for a given gene: one inherited from his mother and the other from his father. However, this does not mean that among humans, there are only two different alleles for each gene. The major histocompatibility (MHC) genes are a clear example of this, since there are multiple combinations for each MHC class. For instance, there are 40 very similar alleles only for the HLA-B27 subtype.

zubka84 [21]

This is because plants are never deficient in organic carbon availability. The inorganic fertilizers only deal with their mineral need and that;s why they don't participate in carbon cycle.
