Answer: b
Explanation: asexual have identical offspring sexual will have different/unique offspring which means they won’t be the exact same.
Answer:
Answer is C.
Explanation:
For A and B, a base substitution affects one of the three bases that comprise a codon, the DNA/RNA unit that corresponds to a particular amino acid. If one base is substituted, one codon and therefore one amino acid will be affected. Codons have built-in redundancy, so even by changing one base, the new codon sometimes still corresponds to the same amino acid. Therefore, a base substitution at most affects one amino acid, and sometimes doesn't affect it all.
Frameshift mutations cause a lot more trouble. These occur when you have a deletion or insertion that changes the number of bases in your gene. As a result, the "frame" of the codons changes (everything shifts one way or the other by the number of bases added/removed). This affects EVERY codon downstream of the mutation, so you can imagine that such a mutation would have a bigger effect the closer to the start of the gene it occurs. This is why C is correct.
Answer:
Shared derived characters can be used to group organisms into classes.
Explanation:
For example, amphibians, turtles, lizards, snakes, crocodiles, birds and mammals all have, or historically had, four limbs.
Answer:
<em>The correct option is 'replication of chromosomes.'</em>
Explanation:
Mitosis can be described as a type of cell division in which two daughter cells are produced which are identical to the parent cell. crossing over or independent assortment does not occur during this process. The cells produced by this method do not have to replicate their chromosomes. Hence, this option is not true.
Other options are true like the alignment of chromosomes along the cell's equator happens during the metaphase of mitosis.
