Answer:
DNA can be likened to a zipper. As with a zipper, the two DNA strands are connected by hydrogen bonds formed between nucleotides. When replication occurs, the twisting of the strands unravels, akin to opening a zipper. The strands separate, just as the teeth of a zipper do when it is unzipped. Each strand is capable of generating a new strand.
However, just like improper handling or wear can damage a zipper, DNA replication can also introduce errors that may result in mutations.
Weather alterations can affect our emotions and perceptions. Meteorology is the discipline focused on weather prediction.
Answer: A.
Explanation: Methane has a significantly greater warming effect on the atmosphere compared to carbon dioxide.
Utilize the Hardy Weinburg equation pertaining to allelic frequency.
P2+2pq+q2=1
Calculating gives us 174/1378 = 0.126 = q2
Consequently, q2 equals 0.126, which means q = 0.355.
<pGiven that q = 0.355 and noting that p + q = 1, therefore
P = 1 – 0.355 = 0.645.
To determine the population of homozygous dominant (p2);
(0.645)2 x 1378 = 0.416 x 1378 = 573.
For the heterozygous population (2pq);
(2 x 0.645 x 0.355) x 1378 = 0.458 x 1378 = 631.
The number of recessive individuals (q2) equals 174.
