The ciliary muscles behind the iris shape the lens by pulling the choroid up and relaxing the suspensory ligaments. The ciliary muscle changes the shape of the lens within the eye, not the size of the pupil which is carried out by the spincter pipillae muscle and dilator pupillae. When the ciliary muscle is relaxed, the choroid acts like a spring pulling on the lens via the zonule fibers causing the lens to flatten, and when the muscle contracts, it stretches the choroid, releasing the tension on the lens and thus they become thicker.
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.
Explanation:
The only group with an endoskeleton is A or D because you put the same answer choice twice
Answer: Diploid
Explanation : It's going to be identical Diploid cells
because diploid cells are stomach cells and the liver is beside the stomach which means that when liver cells divides to create a new cell they'll end up being diploid cells
Mitochondria is the organelle which is involved in cellular respiration and that is linked to development. The primary function is to perform cellular respiration.
Mitrochondria which is also known as powerhouse of the cell Because 32 ATP are created from this organelles. It is produced energy in the form of ATP when cell respire.Oxygen and glucose both are the reactants in the process of cellular respiration.
The major product of cellular respiration is ATP which is waste products include carbon dioxide and water.Cellular respiration takes place in mitochondria, which are often called the cell's "powerhouses" because they make maximume no of a cell's ATP. Glycolysis splits glucose into two three-carbon molecules and makes two molecules of ATP.
