Answer:
The correct answer is D Sister Chromatids may not attach to each other.
Explanation:
Centromeres are the specific point to which the sister Chromatid binds.That means Centromere function to hold the sister Chromatids.
Now according to the question if mutation causes formation of defective centromere then the normal functioning of that centromere will be hampered.
As a result the sister chromatid may not attach to each other.

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:
- <u>North American glacier:</u>
About some 15,000 years ago earth faced a catastrophic event of ice age termed as Last Glacial Maximum(LGM), which covered most of the globe. As the northern region of the American continent, along with that most of the region in the European lands. Which made it very hard for the living beings to survive.
Explanation:
- <u>Effects on Plants-</u>
- The process of producing more food was been halted by the severe conditions globally and there were more unfavorable conditions for the plants, as the level and height of ice over the surface was in the range of Km's. As the trees and plants did not had any water available due to low temperature in the region.
- As most of the Amazon was in scattered form and the rain forests were greatly effected by the ice age, as it covered the surface of the land in the north American region.
- Due, to too much ice and lack of fertile soil available there were less crop and less trees developed, which caused more severe conditions.
