Answer:
The correct answer is: fat in the small intestine.
Explanation:
Cholecystokinin, abbreviated to CCK, is a <u>hormone produced in the small intestine that participates in digestion</u>. Its secretion is stimulated by fatty acids in the small intestine (more specifically, in the duodenum) and by the introduction of hydrochloric acid.
Cholecystokinin has the functions to 1) <u>contract the gallbladder</u><u> so it releases the stored bile into the intestine</u>, and 2) <u>stimulate the secretion of </u><u>pancreatic juice</u><u>, which induces satiety</u>.
Hormones can be divided into three classes. lipid-derived, amino acid-derived, and peptide (peptide and proteins) hormones. Cholesterol is a fat and fats are lipids. They fall into the protein and lipid category.
The endoplasmic reticulum is, in essence, the transportation system of the eukaryotic cell, and has many other important functions such as protein folding. It is a type of organelle made up of two subunits – rough endoplasmic reticulum, and smooth endoplasmic reticulum. It usally has ribosomes attatched to it.
The answer is B). Because Centrioles play role in Mitosis. Prokaryotes don't divide by Mitosis. They divide by binary fission.
Answer:
It is a beneficial mutation.
Explanation: Mutations are permanent changes in the nucleotide sequence of a DNA. Mutations can beneficial, neutral and harmful or deleterious. When change in the nucleotide sequence of DNA a mutation enhances the effectiveness of a protein or improves the protein function, it is said to be beneficial. When a mutation causes the synthesis of a protein which have the same amino acid as the original protein and performs the same function as the original protein, it is said to be silent or neutral. When a mutation results in the synthesis of a protein with an altered amino acid sequence and a nonfunctional protein, it is said to be harmful.
