Answer:
the scientist has determined that the chemical isolated from charcoal-grilled meat is an oxidant.
Explanation:
oxidants are oxidizing agents. oxidants have the capacity to damaging living cells. vitamin C on the other hand is an active antioxidant, hence it was able the breakdown of the cells.
Answer:
9 out of 16 offsprings
Explanation:
This question involves two genes in guinea pig; one coding for coat texture and the other for coat color. The alleles for smooth coat (S) and black coat (B) are dominant over rough coat (s) and white coat (b).
In this question, two heterozygous guinea pigs were crossed i.e. SsBb × SsBb. The gametes produced by each parent is as follows: SB, Sb, sB, sb. Using these gametes in a punnet square (see attached image), the proportion of offsprings will be:
Smooth black coat (S_B_) = 9
Smooth white coat (S_bb) = 3
Rough black coat (ssB_) = 3
Rough white coat (ssbb) = 1
Hence, according to this question, 9 out of 16 offsprings will have a smooth black coat on average.
