False, if too many individual organisms die, the speices might die out
Elis [28]3 years ago
7 0

Answer:

     The right answer to this question is option B. False.

Explanation:

      The main reason why this is not true is that natural selection is totally dependent on food chain and environment as a whole. This means that, there's a need of a whole population for a single organism to pass their adapted genes to another one. For example, if there's an environment with a certain kind of food for squirrels, and something happens to this environment that the food there is another type, if only one squirrel is born with the gene to eat this food, natural selection will kill not only this one at the end of its life, but the rest of the population that couldn't adapt to it.

How does a new mammoth egg cell get chromosomes from each of the parents?
nikitadnepr [17]

Answer:

An egg or sperm only has half of the parent's sex chromosome pair. An egg will always have an X chromosome, since the woman's sex chromosome pair only has Xs. Sperm can have either an X chromosome or a Y chromosome. If a sperm with an X chromosome fertilizes the egg, the new cell will have two X chromosomes. One came from the father's sperm and one came from the mother's egg. Since the sex chromosome that is made is XX, the cell will grow into a girl baby.
