Answer:

The sperm and egg have 1/2 the amount because when the sperm fertilizes the egg, it equals out to the regular amount of chromosomes. That is why we have half chromosomes from our dad and half chromosomes from our mom, equaling out to normal amount of chromosomes.

It makes sense to me that that Sperm and Egg cels have only half the amount of chromosomes than a normal cell because, you get equal chromosomes from when they come together. so you get equal amount of traits from both sides.

Explain how a nymph grows or the molting process used for growing.
Alchen [17]

Answer:

As insect nymphs grow larger, their exoskeleton becomes too tight and they must replace it. Once a nymph outgrows its exoskeleton it will go through a process called molting, in which it leaves the old “skin” or exoskeleton behind. The new “skin” will harden and become the new exoskeleton

Cells must be alive to use energy and do work dose passive transport occur in a cell that is dead? Why or why not?
Orlov [11]

Answer:

<h3>Yes, Passive transport can occur in dead cells.</h3>

Explanation:

For passive transport to occur, a concentration gradient has to be formed across a permeable or semi-permeable membrane. If the cell membrane of the dead cell, which is a semipermeable membrane, is intact and a concentration gradient has formed on both sides, passive transport can occur.

A concentration gradient is the difference in the concentration of solute molecules  across the membrane. Passive transport will allow solute molecules to travel from the higher concentration of the solute to the lower concentration across a membrane till equilibrium is reached, that is, both the sides of the membrane has equal concentration of the solute.

The transport of the solvent can occur as well, from higher concentration to lower concentration.
