Answer:
33
Explanation:
Gametes (sperm or egg) have half the chromosome of a diploid cell. That's why they are haploid cells.
If chromosomes come from a cell with 66 chromosomes, sperm will have 66/2 = 33.
That's why us humans have 46 chromosomes, but our egg or sperm has only 46/2 = 23 chromosomes.
The answer to your question is <span> It's a physical system that is not affected by any other system. They don't really exist, other than the universe.
You might incorrectly state that an object is space is isolated from everything else, and it does seem that way. It's still affected by gravitational fields, but negligibly.
However, you look at the universe which you define to be everything ever. There is nothing else that exists to interact with it, so it is an isolated system.</span>
Answer:
The correct answer is - reuptake of the neurotransmitter molecule into the axon through a membrane transporter.
Explanation:
The action of a neurotransmitter at the postsynaptic cell or postsynaptic potentials is terminated by any of these mechanisms that are enzymatic degradation, diffusion or reuptake into the presynaptic cell by specific transporters.
After the desired biological response by postsynaptic potentials, in order to avoid over stimulation or termination of the postsynaptic potentials the neurotransmitter is taken back into the axon through a membrane transporter. This mechanism is to maintain a balance.
