A raven's claws are made out of the protein keratin. Describe how this fact is related to the raven's genes.

The proteins that are made in an organism are encoded by particular genes.

Every cell in an organism has the same chromosomes and the same genotype. But still, every cell of the body will have different functions because of different proteins being produced. The genes which encode for a particular protein might be active in one cell but suppressed in another type of cell.

For example, the genes which code for the protein keratin are active in the raven's claws but inactive in other parts or cells of the raven's body.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
