The Kerbs Cycle occurs in the, D.mitochondria
Limited factors would mean that as the population in a community grows individual species would have to compete for those limited factors as the population reaches its carrying capacity. Also, the population as a whole would only be able to reach a certain number before falling due to there not being enough of the limited factors (ex. food) for that population to continue growing exponentially.
Answer:
Urey and miller cooked a "primordial soup" with Hadean gases, water and electricity to make <u>glucose</u>, <u>acetic acid</u>, <u>amino acids</u> and <u>lipids</u>.
Explanation:
In the Miller-Urey experiment, the aim was to reproduce the conditions of the earth before the existence of life, with the objective of demonstrating the formation of organic matter from inorganic molecules.
The scientists took water and gases present in the Hadean eon —previous to the existence of life— such as methane, carbon dioxide, hydrogen, nitrogen and even ammonia, the primordial soup. This mixture was subjected to electrical discharges, inside closed containers.
The results were some organic molecules, including glucose, acetic acid, amino acids and fatty acids. In these results the presence of macromolecules, such as proteins or nucleic acids, is not appreciated, however it was a significant contribution to the knowledge of the origin of life on earth.
Answer:
Phospholipid bilayer.
Explanation:
The plasma membrane (also known as the cell membrane or cytoplasmic membrane) is defined as a biological membrane that separates the interiors of a cell from its external environment.
The plasma membrane has a function that protects the cell from its external environment, mediates cellular transport, and transmits cellular signals.
It is composed of a lipids bilayer (phospholipids and cholesterol), (phospholipid is a lipid made of glycerol, two fatty acid tails, and a phosphate-linked head group) with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules which hence, regulates the movement of substances in and out of cells. Plasma membranes is very flexible in order to allow cells change form example, red blood cells change shape as they pass through narrow capillaries.
When climbing a mountain, we can observe transitions in biological communities that are analogous to the changes in biomes at different latitudes.
