Explanation:
The nucleus (plural, nuclei) houses the cell's genetic material, or DNA, and is also the site of synthesis for ribosomes, the cellular machines that assemble proteins. Inside the nucleus, chromatin (DNA wrapped around proteins, described further below) is stored in a gel-like substance called nucleoplasm.
Answer: "To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the right concentrations of ions and molecules in living cells."
The way that neurons communicate is through synaptic vesicles which release neurotransmitters.
<h3>What are Neurons?</h3>
The neurons are the basic structural and functional unit of the nervous system.
These neurons are able to communicate to each other through the neurotransmitters that are released by synaptic vesicles.
The neurotransmitters are chemical messengers that carry chemical signals from one neuron to another upon the generation of an action potential.
The synaptic vesicles are the organelles that house these neurotransmitters.
