Answer: Arginine is an amino acid that is incorporated into proteins. So if cells can not make or obtain arginine, the cell can not make proteins needed for survival.
Explanation:
Arginine is an amino acid used to build proteins, and it is classified as a semiessential or conditionally essential amino acid.
Proteins are large molecules consisting of long chains of amino acids. They perform many functions such as catalysing metabolic reactions, providing structure to cells and organisms, and transporting molecules, among many others.
Most notably, arginine is part of proteins that play an important role in many different processes such as cell division, immune function, wound healing and the release of hormones. <u>Without this amino acid, the cell cannot manufacture the proteins necessary for proper functioning</u>. So the cell dies because it cannot function properly.
Answer: A . Has its collagen fibers randomly orientated.
Explanation:
In the microscopic anatomy of the bone, an osteon (basic microscope unit of the bone) can be arranged into two categories; woven bone or lamellar bone.
As the name suggests woven bone is characterized by the random orientation of the collagen fibers . These collagen fibers haphazardly form to give the visual appearance of an intertwined (woven) network of collagen fibers.
Due to the randomness of the collagen fibers orientation woven bone is thus mechanically weaker than lamellar bone. Woven bone is formed/produced when osteoblasts produce osteoids rapidly within the bone matrix thus woven bone has the ability to form quickly as needed.
Woven bone is thus immature bone or pathologic bone with no stress orientation, it has a high percentage of osteocytes per unit volume and a high rate of turnover.
Answer:
e. Quantity of oxygen consumed when the food is burned
Explanation:
The quantity of oxygen that's used up is known as an indirect measure for amount of energy that's released from the food you burn and Bomb calorimeters may be used to estimate the amount of energy in food.

Answer;
-Telophase
Explanation;
-The spindle apparatus disintegrates during the telophase of mitosis. Telophase is the final stage of mitosis.
-During this phase, the sister chromatids reach opposite poles. The small nuclear vesicles in the cell begin to re-form around the group of chromosomes at each end.
-As the nuclear envelope re-forms by associating with the chromosomes, two nuclei are created in the one cell. Telophase is also marked by the dissolution of the kinetochore microtubules and the continued elongation of the polar microtubules.
