Ans.

The codons show genetic codes, made up of triplet of nucleotides in DNA or RNA that code for specific amino acids. The different codes can code for a same a amino acid. When a substitutional mutation occurs in genetic material, it shows substitution of one nucleotide pair for another and leads to formation of a different codon.

The first mutation that leads to CAU to CAC, it will not show any potential damage as both CAU and CAC codons code for histidine amino acid.

The second mutation that leads to UGU to UGC will also not show any damage to protein as both of these codons code for cysteine amino acid.

The third codon, that results UCU to UUU will cause a potential damage to protein as UUU codes for phenyl alanine (an aromatic, non-polar amino acid) and UCU codes for serine (a polar amino acid).

Thus, the correct answer is 'option C).' as in a protein, substitution of serine with phenylalanine will lead to change in structure and function of that protein.

(04.03 HC)A scientist records the populations of two species over a period of time.
Lina20 [59]

Answer:

The likely explanation is that population 1 had traits which were more favorable to its survival than population 2's in the new conditions.  It wouldn't have to do with food competition, but the traits they already have that may or may not be conducive to their survival in the new conditions.

Explanation:

Let me explain. Say a drought occurred on an island. Population 2 relied on eating bugs that lived in the green grasses. Population 1 relied on eating cactus fruit, which is drought-resistant. Say that because of the drought, population 2 started to decrease since there were less bugs to eat because the grasses dried up. Population 1 is unaffected because the bugs they eat were still in abundance.

This all has to do with the concept of natural selection. Species with traits that are good for their environment will likely do well unless a change in conditions occurs which makes their traits no longer favorable.

Hope that makes sense!
