Apex plus i just did it please mark brainliest if you want id appreciate it
Answer:
"The axon, the long, thin part of the neurone along which the impulse passes, is covered in a fatty myelin sheath, which acts as an electrical insulator."
Explanation:
"The dendrites receive incoming nerve impulses from other neurons."
Answer is: active transport.
In active transport<span> because energy is required to move the sodium and potassium ions against the concentration gradient. There is two type of active transport:
1) </span>Primary active transport directly
uses metabolic energy (adenosine triphosphate- ATP) to transport molecules
across a membrane.
2) In secondary active transport (coupled
transport) there is no direct coupling of ATP, energy derived from
the pumping of protons across a cell membrane.
They both perform photosynthesis.
Answer:
The oncogenes and the tumor suppressor genes
Explanation:
the oncogenes, which function as positive growth regulators, and the tumor suppressor genes, which function as negative growth regulators.
