<span>In biochemical reactions,
it is mostly triggered by enzymes. Enzymes are important components in the
process that involves metabolism and digestive functions, further, most of
these enzymes are proteins. Proteins are biological macromolecule and mostly
composed of enzymes. Proteins play a role in the physical make-up of a cell or
acts as a cytoskeleton –maintains cell shape and figure. These proteins plays
different roles and works with nucleic acids and other macromolecules in the
cells including cell cycle, cell adhesion, immune response and cell indicators.

Answer:
C. Acclimatization
Explanation:
I think of "acclimatization" as acclimating to a new environment, also it's clearly derived from acclimating. It's just another way to say adjusting to the environment, and isn't necessarily restricted to high elevations. It could also be temperature, or humidity. I hope this helped!
Answer:
Cell of and integument
Explanation:
When flowering plants reproduce by sexual reproduction, they form seeds contained into fruits. The fruit is derived from the maturation of the flower's ovary (female part) after fertilization.
A mature seed contains three generations:
- a diploid embryo (the new sporophyte),
- The embryo is surrounded by haploid female gametophyte tissue that supplies nutrition
- All the above structure is in turn surrounded by the seed coat (diploid parental sporophyte tissue). The seed coat is produced by integument cells to protect the embryo during its development and before its can germinate. As it is produce by it parental plant, its ploidy level diploid.
In contrast, the generative nucleus and sperm cell are part of male gametophyte (pollen grain) and therefore haploids. Synergid cell is part of embryo sac, therefore belongs to female gametophyte and thus being haploid. Finally, cell of endosperm is usually derived from the fusion between a sperm cell and one of the two female gametes present within the embryo sac, thus being triploid.
Answer:
50
Explanation:
egg cells and sperm cells contain half of the chromosomes of a regular cell in an organism, so the number of chromosomes in a heart cell must be double of the chromosomes in a egg cell.
Answer: Thrombus Formation
Explanation:
Atherosclerosis is a chronic, progressive disease in which the plaques starts building in the walls of artery. These plaques are the deposition of the cholesterol and other lipids, calcium and inflammatory cells known as macrophages.
Once these substances starts depositing in the artery it can lead to thrombus formation which is not cured by itself.
The Atherosclerosis is the predisposes to the thrombus formation which can cause myocardial ischemia.
