Missing options:
A) the formation of recombinant DNA
B) the synthesis of a different polypeptide
C) crossing-over
D) polyploidy
Answer:
B) the synthesis of a different polypeptide
Explanation:
The statement highlights a change in the codon sequence from UCG to UGC. If we look at the table of amino acids, we would realize that UCG encodes for "<u>Serine</u>" whereas UGC encodes for "Cysteine" amino acids. This single change in DNA sequence is known is <u>mutation</u> or <u>single nucleotide polymorphism (SNP)</u>. Finally, the change in amino acid will result in the synthesis of a different polypeptide which contians a different amino acids. See figure attached for codon table.

Answer:
The correct order is -
a. 5 > 3 > 4 > 1 > 2 .
Explanation:
In sedimentary rocks, the bottom layer of the rock form initial and the fossils found in them would be older and the layer on top deposited the latest so the fossils found in the top layer would be the youngest.
Newer layers form or deposited on the layers of the oldest or bottom layer of the sedimentary rocks. Hence, the fossils present in the bottom layer would be the oldest fossil and newer fossils will be above them and the youngest would be top.
Thus, the correct answer is - a. 5 > 3 > 4 > 1 > 2 .
An autotroph is a living organism that produces complex compounds such as carbohydrates, fats and proteins. They are producers in a food chain, in contrast to heterotrophs who are consumers.
