Calcium deficiency disease (hypocalcemia) --- like osteoporosis, osteopenia !!
Crustacea(ns) form a very large group of arthropods.
Inheritance Example
With respect to eye color, the allele for brown eyes (B) is dominant, and the allele for blue eyes (b) is recessive. If a person receives dominant alleles from both parents (BB) she will have brown eyes. ... But if she receives recessive alleles from both parents (bb), she will have blue eyes.
Hope this is what you were looking for!
The correct answer is B.
Channels and pumps are transmembrane proteins that create hydrophilic tunnels across the membrane. This allows molecules to be diffused through them. The channels and pumps are highly selective and only allow the diffusion of specific molecules. The channel's structure blocks the contact of the molecule with the head and tail of the phospholipids that form the membrane. As we said, the channels and pumps are proteins, so they are formed by amino acids. Therefore, the molecules passing through channels and pumps, only come in contact with the amino acids.
