I believe the correct answer to this question is:
“excessive heat to the gonads”
<span>The gonads is the human organ which
produces the gametes (sperm cell or egg cell). In this case, that is the testis
or ovary. When too much heat is in direct contact with the testis, this can
affect the reproduction of sperms.</span>
Answer:
I believe it is D With the help of my notebook
Answer:
The correct answer is A products are formed from the reaction by breaking and forming of new bond.
Explanation:
In a chemical reaction, reactants participate which reacts with each other to generate the product of the reaction .
Zn+H2SO4 = ZnSO4+H2
In the above reaction Zinc attacks the sulfate group of H2SO4 as e result the bond present between hydrogen atom and oxygen linked to sulfur atom undergo cleavage liberating sulfate and hydrogen molecule. This sulfate then form new covalent bond with Zinc which leads to generate ZnSO4 and H2 gas is liberated as a byproduct.
Answer:
Dehydration reaction (a condensation reaction)disaccharide will provide energy for chemical reactions in the body to take place.
Explanation:
The Condensation Reaction is an organic reaction in which two molecules combine to give a single product accompanied by the formation of a molecule of water H2O. Disaccharides are produced when two monosaccharides are chemically combined. The bond called O-glycosidic, is the bond by which monosaccharides join to form disaccharides or polysaccharides. In this type of bond, an OH group of an anomeric carbon of a monosaccharide reacts with an OH group of another monosaccharide, releasing a water molecule.The main function of disaccharides is to provide energy to the cells of the human body, or glycogen. This is achieved through enzymes that act in the synthesis of the disaccharide, extracting glucose. Among the main and best known enzymes that act in this process are insulin for sucrose, lactase for lactose, and trehalase for trehalose.
I believe strong acidic conditions are no used because the amine will be completely protonated. The strong acid condition decreases the rate of reaction of the amine. The fastest imines formation occurs with a pH of 4-5. When there is no free electron pair, it is no longer a nucleophile and so nucleophilic addition cannot occur.
