How does cell transport like diffusion impact homeostasis
Reil [10]

Answer:

homeostasis is the state of steady internal physical and chemical conditions maintained by living system.

Diffusion is an important process for living things; it is how substances move in and out of cells.

Diffusion helps maintain homeostasis by creating specific concentrations of molecules inside the body compared to outside and Cells in homeostasis are successfully maintaining the internal conditions necessary for basic functioning

The cell needs to export waste and other molecules, and import fuels and fluids. Plasma membranes allow water, oxygen and carbon dioxide to pass through by osmosis, or passive diffusion.

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.
