Answer:
Dehydration reaction is the chemical reaction that links the MONOMERS together by removing a HYDROGEN ATOM form one monomer and an OH GROUP from a second molecule creating a COVALENT BOND between these molecules. The H ATOM and the OH GROUP will be bonded as well to form a water molecule. On the other hand, HYDROLYSIS is a chemical reaction that BREAK down POLYMERS introducing a water molecule and breaking the covalent between the monomers in the polymers.
Explanation:
Carbohydrates, proteins and nucleic acids are polymers of simpler sugars, amino acids and nucleotides respectively. Monomer molecules are joined together to form a polymer by dehydration reactions and a water molecule is released. On the other hand, hydrolytic reactions break down polymers into monomers by adding water molecules to them.
For example, a dehydration reaction joins two amino acids together by a peptide bond (a specific type of covalent bond that joins the amino acids) to form a dipeptide. During the reaction, one amino acid loses an H atom and the other loses its OH group to release a water molecule.
Breakdown of proteins into amino acid occurs by hydrolytic reactions in which water molecules are added to amino acids to breakdown the peptide bonds between them.
Answer: B (gallbladder)
Explanation:
Bile acids are digestive fluid produced by hepatocytes cells of the liver. Once the bile are produced by the liver, it passes through the bile duct and then the cystic duct, and reaches the gallbladder. The gallbladder is the storage site for bile acids. The gallbladder release bile acids which are responsible for breaking down fats and lipids in the small intestine.
Answer is gallbladder
Answer:
The cuticle is a transparent outer layer of the hair shaft. It is made of scales that overlap one another and protect the inner layers of the hair (Figure 3-4). The scales point from the proximal end of the hair, which is closest to the scalp, to the distal end, which is far- thest from the scalp
Explanation:
The option which correctly describes a way in which Earth's atmosphere interacts with the geosphere is that it <span>provides a medium for cycles that provide nutrients to living organisms - C is the correct answer.
Atmosphere creates favorable conditions for the creation of food for living organisms via these cycles. </span>
C) is the best answer because atmosphere deals with gases and hydrosphere deals with water.
Hope this helps... BTW you took out (water) in the question C
