Answer:
One major side effect of DDT was the extreme damage to bird populations. DDT caused the shells of bird eggs to become extremely thin, which made them prone to breaking from minor disturbances and failing to thrive due to temperature regulation issues. It also slowly poisoned animals, especially birds that fed on insects that were poisoned by DDT. A notable bird species that was affected by DDT is the bald eagle. At one point in the 1960s, bald eagles nearly went extinct due to various effects of DDT. The threat of one of the most recognizable animals in America going extinct led to lawmakers trying to ban DDT.
This supports the continental drift idea by example: a fossil animal was in one continent and then you find it in another. This is splitting the continents.
If the mutation occurs during meiosis, the mutation will be incorporated into a gamete. If that gamete is the one that eventually fuses with another gamete (i.e. if it's the sperm that fertilizes the egg), that mutation will be passed on to the offspring. As all the offspring's cells are the result of the first two gametes, all the organism's cells will have that mutation. Obviously this can have dire consequences for the offspring, if the mutation is harmful.
A, B, D, F are the gated embedded
proteins in model 1 allow potassium ions through the membrane. Sodium ions are
necessary for regulation of blood and body fluids, transmission of nerve
impulses, heart activity, and certain metabolic functions. Physiologically, it
exists as an ion in the body.
