Explanation:
Cell membranes are selectively permeable. Some solutes cross the membrane freely, some cross with assistance, and others do not cross at all. A few lipophilic substances move freely across the cell membrane by passive diffusion. ... Large molecules do not cross intact cell membranes, except in certain special cases.
The allele symbols on the outside of the punnett square represent the alleles in the gametes . Because when we done cross we got the gametes only . Example AABB X aabb , then we got the gametes AB and ab . This represent AB and ab are the alles of the gamete only . A allele is the alternative form of gene , if one is dominant other one is recessive.

D. “The scientific name Asteroidea was given to starfish by the French zoologist de Blainville in 1830. It is derived from the Greek aster, ἀστήρ (a star) and the Greek eidos, εἶδος (form, likeness, appearance). The class Asteroidea belongs to the phylum Echinodermata.”
E. “First, primates have larger eyes than many other mammals of comparable body size (Ross & Kirk, 2007). Having large eyes ensures that a large image is formed on the retina (Walls, 1942; Land & Nilsson, 2002). This large retinal image may then be sampled by many photoreceptors, improving visual resolution. Primates have flexible shoulder joints and and strong clavicles or collar bones that help them use their arms more effectively than other species of animals. Most primate can hold their bodies erect and some species, including humans, can walk on two legs instead of four.”
Answer: Tissue that carries messages throughout our bodies is called nerves. Nerves conduct electrical impulses between the brain and brain stem to all parts
