Answer:
Option D.
Explanation:
As stated in Mendel's law of segregation.
Yes, i think the change in temperature will affect the animals phyisiology
Answer:
Fraternal twins are from two seperate eggs.
Explanation:
The first part of the question is missing but any difference between fraternal twins can be explained by the fact that two seperate eggs are fertilized during the pregnancy so they have different genomes which leads to having different dominance of different genes and this leads to different expressions of this genes.
I hope this answer helps.
Answer:
Hi!
The answer is (C) Both (a) and (b)
Explanation:
Drug Metabolism:
- Drug metabolism is divided into two steps: Phase 1 and Phase 2 reactions.
- Phase 1 reactions involve the degradation or formation of functional groups.
- Phase 2 reactions involve the conjugation of the drug or its Phase 1 intermediate with a polar conjugating molecule. Phase 2 generally performs the detoxification step in the drug degradation process.
- Phase 2 or conjugation reactions are further divided into 2 types:
- Type 1: Glucoronidation and sulfonation: An activated conjugating molecule such as glucoronic acid, sulfate or glutathione etc. is combined with the drug to form a conjugated molecule.
- Type 2: Amino acid conjugation: An activated drug or substrate is conjugated with an amino acid such as glycine or glutamine.
Glutathione Conjugation:
Glutathione is a tripeptide found in most tissues, particularly in the liver. It performs important detoxification functions for all cells. The enzyme, glutathione S-transferase conjugates glutathione with drug intermediates to form a drug-glutathione conjugate. This conjugate can easily be excreted through bile or urine.
Amino acid Conjugation:
This is an important reaction in xenobiotic biotransformation; particularly for xenobiotics with carboxylic group or an aromatic hydroxylamine groups. Drug intermediates combine with glycine or glutamine to form an amino acid conjugate.
