Somatic cell chromosomes (body cells) are in pairs. if you mean 12 chromosomes,Then there will be 6 pairs, groups of two, chromosomes. The gamete (aka sex cell) will thus contain 6 chromosomes.
One chromosome from each pair ends up in one gamete, normally.
Answer:
Enzymes catalyze a reaction which in presence of a catalyst proceeds the reaction faster. Inorganic catalysts promote a chemical reaction between many different reactants. Enzymes are proteinaceous in nature whereas inorganic catalysts are not proteinaceous in nature.
Explanation:
Answer:
B. In the small intestine, carboxypeptidase attacks peptide bonds.
E. Pepsin causes the hydrolysis of some of the peptide bonds in proteins.
Explanation:
The digestion of protiens doesn't occur in mouth, it occurs at only 2 locations in GIT :
- In the stomach
- In the small intestine
Digestion of protiens start in stomach causing the stimulation of gatrin hormoone which stimulates the release of gastric juice containing HCl , Pepsinogen , Rennin (in infants). The pepsinogen is activated to pepsin by HCL and pepsin itslef, and cause hydrolysis of the peptide bonds in the protiens.
The remainder of protien digestion occurs in small intestine as a result of the action of enzymes including trypsin and peptidases. Carboxypeptidases attack the peptide bonds and result in cleavage.
Answer:
Either B or D
Probably B because genetically modified
Explanation:
its not A or C because:
A doesn't do anything (it just reduces the population of dogs)
C only alters a specific dog's behaviour, not all of them
Because metamorphic is created by a igneous or sedimentary rock heating up and changing into a metamorphic rock
