PLEASE HELP!! 20 Points!
Lesechka [4]

Similarities:

Both involve ion movement. Both use ion channels to move ions across the cell membrane, in or out of the cell.

Differences:

Passive Transport (or Diffusion) moves ions from high concentration to low, using no metabolic energy. Active Transport moves ions from low concentration to high, using metabolic energy in the form of ATP.  Active Transport uses an ion pump (or Sodium/Potassium pump) to move 3 sodium ions out of the cell and 2 potassium ions in to the cell through the energy of 1 ATP molecule.  

In active transport particles move against a concentration gradient and therefore require energy which must be supplied by the cell. Carrier proteins that are found in the cell membrane of cells use energy to transport molecules or ions across the membrane, against the concentration gradient.

Passive transport is a naturally-occurring phenomenon and does not require the cell to exert any of its energy to accomplish the movement. In passive transport, substances move from an area of higher concentration to an area of lower concentration.

Answer:

go through a metamorphosis

Explanation:

METAMORPHOSIS is the change in the form and often habits of an animal after the embryonic stage during normal development.

For Example: the transformation of a caterpillar into a butterfly, OR a tadpole into a frog.

Note that the other options given are WRONG because they are characteristics or features of either of them, NOT both.

A nerve poison that blocks acetylcholine receptors on dendrites would _____. a nerve poison that blocks acetylcholine receptors
nata0808 [166]
Nerve poisons, or nerve gases are organic chemicals that interfere with the mechanism by which nerves transfer messages to organs. The interference is as a result of the blocking of acetylcholinesterase, and enzyme that catalyzes the breakdown of acetycholine, a neurotransmitter. Therefore, a poison that blocks acetylcholine receptors on dendrites may reduce or decrease the binding of acetycholine to its receptors on the postsynaptic membrane.
