Intake of water and nutrients
Answer:
there is a link
Explanation:
glycolysis produces pyruvate which feeds into the krebs cycle
krebs cycle also generates redox agents(NADH and FADH2) needed in the etc
Answer:
The answer is B. If the mutation causes a change in the protein sequence, then a person's physical traits will be affected.
Explanation:
Mutations:
Mutations are changes or alterations in the DNA sequence that codes for functional proteins.
Types of Mutations and their Phenotypic Effects:
Mutations are of various types but those specifically affecting the DNA sequence are called point mutations. Point mutations are of the following types:
- Substitutions
- Deletions
- Insertions
Substitutions:
- Substitutions are the alterations of a single base pair. These are further of three types:
- Nonsense mutations change the sequence in a way that a stop codon is introduced. This produces a truncated, non-functional protein.
- Missense mutations replace one codon with another codon. This results in alterations in the amino acid sequence of the encoded protein. This will also be non-functional.
- Silent mutations change the DNA sequence but in a way that the new codon codes for the same amino acid. Therefore, the sequence of the protein is conserved.
- Deletions remove one or more base pairs from the sequence, resulting in a changed or truncated protein.
- Insertions add one or more base pairs, resulting in a no-functional protein.
- Both insertions and deletions (if one or two bass are added or deleted) alter the frame of reference of the DNA sequence.
Answer:
BT-modified crops may kill pollinators, reducing crop fertility in seed and fruit crops
Explanation:
The correct answer is BT-modified crops may kill pollinators, reducing crop fertility in seed and fruit crops. People would prefer that beneficial pollinator species become BT-immune. There is little concern about cross-genus exchanges of genetic material leading to BT-toxic bee stings, or that pollinating species will come to prefer BT-modified crops and ignore natural, unmodified crops.
