Answer:
fovea
Furthermore, the fovea has about 50 cone cells per 100 micrometers squared and has an elliptical shape horizontally. Given this high cellular concentration, it is expectedly the location of the highest visual acuity, or resolution, in the eye.
Explanation:
The nucleus is the control center of the cell. It is a storehouse for DNA (genetic information). Therefore, your answer would be DNA.
A mitochondria would not be right because it supply energy to the cell. Ribosomes make proteins. RNA is a single string that let messenger RNA (mRNA) pass through the nucleic pore.

Depolarisation
A membrane depolarization is a decrease in the potential difference between the outside of a cell and the intracellular medium, on either side of the plasma membrane, most often due to a positive ion input (Na +, Ca ++, etc.) inside the cell or sometimes due to the release of chloride ions, and involved in the mechanisms of transmission of nerve impulses and muscle contraction.
Hyperpolarization:
The depolarization is followed by a repolarization, thanks to the output of an equivalent quantity of ions k + which causes the return to the state of equilibrium. Then there is a hyperpolarization due to the output of more k + ions than Na + ions, because the potassium channels are slow to close. Finally there is a return to the resting potential.
Hyperpolarization is a term opposite to that of depolarization, it refers to values lower than that observed during the resting potential.
Answer:
Autotrophs are organisms that can produce their own food from the substances available in their surroundings using light (photosynthesis) or chemical energy (chemosynthesis). Heterotrophs cannot synthesize their own food and rely on other organisms — both plants and animals — for nutrition.
autotrophs are known are known as producers because they are able to make their own food from raw materials and energy, such as plants, algae and some types of bacteria.
heterotrophs are known as consumers Because they consume producers or other consumers such as dogs, birds, fish and humans.
