That is because gene expression is a process in the synthesis of proteins and without proteins our organisms could not function properly. Almost all things that occur in our body are results of proteins being synthesized and these proteins travel through our body activating other processes. When not synthesizing proteins, different types of RNA are synthesized.
Answer:
<h2><u>
A. Having a nucleus</u></h2>
Explanation:
Many organisms have nuclei, but certain types of one-celled prokaryotes and bacteria do not have one.
Answer:a molecule containing a very large number of atoms, such as a protein, nucleic acid, or synthetic polymer.
Explanation:
Complete Question:
Which of the following might stimulate the cephalic phase of gastric secretion?
A. stomach distention
B. the production of saliva
C. the thought of food
D. the production and secretion of gastrin.
Answer:
C. the thought of food
Explanation:
Gastric secretion usually occurs in three different phases, namely;
- Cephalic
- Gastric
- Intestinal
The thought of food usually stimulate the cephalic phase of gastric secretion in organisms. The presence of lipids or low pH inhibits Gastric secretion during the intestinal phase.

B) Disaccharides
C) Monosaccharides
</span><span><span>Monosaccharide, disaccharides, and polysaccharides are the three major categories of molecules in Carbohydrates. </span>
Monosaccharides, known as simple sugar, is the simplest form of carbohydrates. Its basic molecular formula is CH2O. Monosaccharides are glucose, fructose, and galactose. Its primary function is to be the source of energy of living organisms. It is also the primary requirement for the formation of disaccharides and polysaccharides.
Disaccharides are formed when two monosaccharides are bonded together through a covalent bond. Common Dissaccharides are sucrose (glucose+fructose) or table sugar, maltose (glucose+glucose), and lactose (glucose+galactose). Its primary function is to provide nutrition for monosaccharides. Sugar in food is mostly dissaccharides.
<span>Polysaccharides are formed when another monosaccharides is bonded to the disaccharides. This bond is called glycosidic bond. Two major polysaccharides are starch and glycogen. Starch is made by plants while glycogen is made by animals. Polysaccharides' major function is to immediately release energy from its storage. When glucose is consumed, some of them are stored and will only be released when the body needs it to satisfy the body's immediate need of energy.</span> </span>
