What is the structure of mitochondrion, cell wall, cell membrane, and the nucleus
Romashka-Z-Leto [24]

Answer:

The mitochondria are called the powerhouses of the cell, where ATP is produced. It is composed of an inner membrane called cristae, and an outer membrane that covers the organelle.

The cell wall is a rigid structure made from(in the case of plant cells rather than bacteria or fungi) cellulose and other rigid fibers.

The cell membrane is a fluid, thinner structure made up of a double layer of phospholipids which are comprised of the hydrophilic heads facing outwards and hydrophobic tails facing toward each other in the layer.

The nucleus  has protons, and neutrons that are contained within it, and electrons around it.

(DNA resembles history, obviously, they aren't meeting with dark torment patients, the DNA in Caucasian Europeans goes about as an authentic guide of past bottlenecks.) Because Europeans with this transformation were to the least extent liable to bite the dust of the dark passing they were the well on the way to survive, which is the reason the calamity of the bubonic torment brought about somewhere in the range of 20% of Caucasian European relatives to do not have these receptors on their invulnerable framework cells which thusly diminishes the danger of resistance illnesses, for example, assistants.
