Red blood cells are disc shaped. It is thought one factor that allows them to have this shape is because they do not have a nucleus. This tends to increase amount of space inside the cell for hemoglobin.
They have a flexible disc shape which helps increase the surface- to- area volume ratio which enables oxygen and carbon dioxide to diffuse across the red blood cell's plasma membrane more readily.
Their disc shape also enables them to squeeze through tiny capillaries that are half their size .

The Arctic tern is a medium-sized bird around 33–36 cm (13–14 in) from the tip of its beak to the tip of its tail. The wingspan is 76–85 cm (30–33 in). The weight is 86–127 g (3.0–4.5 oz.).
Explanation:
Answer:
For effect #1, the mutation will become more common (A). This is because with the organism having more children, the trait will be passed around much faster and will spread to surrounding groups of animals.
For effect #2, the mutation will become more common (A). This is because the disease will kill the animals who do not carry the gene leaving only the animals with the trait, making it much more common
For effet #3, the mutation will disappear (B). This is because the animal carrying the gene will slowly die off. After all, they will not be able to reproduce and pass the gene to their children.
For effect #4, the mutation will remain at a low level (C). This happens because since it procures no change there will be no reason to transfer it so it will become a recessive trait in the animals.
