<span>Refractory period is the period after an initial stimulus when a neuron is not sensitive to another stimulus.</span><span>
During the relative refractory period of an action potential, a larger than normal stimulus is needed to cause another action potential. This is due to the fact that t</span>he voltage gated potassium ion channels remain open long enough to hyperpolarize the axon membrane.
Answer:
of diffusion
Explanation:
Molecules move down a concentration gradient without the need to use energy. This means they move from a high concentration to a low concentration. This occurs across a semi-permeable membrane, like the cell membrane, by simple diffusion.
Answer:
It would just be transmitted to DNA
Explanation:
Ingestion of foreign substances by macrophages and yeast cells by an amoeba is known as <u>Phagocytosis</u>
<u>Explanation:</u>
Phagocytosis that is the name given to the process of ingestion of foreign particles by macrophages. In human body the white blood cells does this function. Macrophages is found in all the tissues. Any foreign particle entering the body is engulfed by this process hence protecting the organisms.
Once a bacteria enters the body it is at once detected and recognised as the foreign particle. Then it is attached to the phagocyte. Then it is engulfed into a vesicle called phagosome. Then this is killed by the process of phagocytosis.
