<span>Three months after fertilization and development of a placenta around the developing fetus, the corpus luteum regresses and forms the corpus albicans.</span> Formed placenta takes over progesterone production (which was the role of corpus luteum) and the corpus luteum degrades into a corpus albicans. The corpus luteum is being broken down by macrophages, in a process called luteolysis. The remains of the corpus albicans may persist as a scar on the ovary.
Reduces water loss compared to other nitrogenous wastes but requires more metabolic energy to produce
Mammals excretes urea as the primary nitrogenous waste product. On the other hand birds, and reptiles excretes uric acid as the primary nitrogenous product. They are called uricothelics because they can convert ammonia to uric acid. Uric acid is a compound similar to purines. This is produced through a complex metabolic pathway thay cost high energy. However it has advantages such as reducing water loss.
The Cytoskeleton is the cell organelle responsible for providing shape and support to all cells. The cytoskeleton is made of protein.
<u>Explanation:</u>
The location where cytoplasm meets the cell membrane, cytoskeleton is found. A cell's cytoskeleton consists of microtubules, actin filaments, and the intermediate filaments. These frameworks give form to the cell and support to organize the parts of the cell.
They also provide a structure for motion, and segregation of cells. Intermediate filaments are a form of cytoskeletal material composed of several fibrous protein strands wrapped together. Keratin is one protein that shapes intermediate filaments, a fibrous common ingredient in hair, nails and skin.
Bar graphs show patterns in data with variables that change over time; Whereas pie charts, show data as parts out of a whole, (such as 100%).
