Answer: c.The process of programmed cell death.
Explanation:
Apoptosis is a kind of programmed cell death process. This can be seen in multicellular organisms. This involves the biochemical changes in the body of the organism which lead to death of cells. The changes associated in the cell during this condition includes the cell shrinkage, blebbing, condensation of the chromatin, nuclear fragmentation, decay in mRNA, and DNA fragmentation.
The answer is phagocytosis.
<span>Phagocytosis is a process which amoeba uses to swallow up large fragments of matter, such as mineral particles, dead cells. These swallowed fragments form a phagosome. The phagosome fuses with a lysosome and forms a phagolysosome inside which enzymes break down those fragments.
Phagocytosis is a specific form of endocytosis.</span>

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.
