D). Carcinogens are chemical factors in an organism's environment that can cause spontaneous mutation.
When it is winter in the Northern Hemisphere, the Southern Hemisphere faces the Sun more directly and thus experiences warmer temperatures than the Northern Hemisphere. Meaning that the date is June 21- summer
Answer:
The main difference between cardiac skeletal and smooth muscle is that cardiac muscles perform involuntary muscular movements of the heart, aiding the heart to pump blood throughout the body, while skeletal muscles perform a voluntary muscular movements of bones, aiding physical movements of the body such as walking, running, and writing.

A mutation within a gene that will insert a untimely cease codon in mRNA would result in a shortened polypeptide chain.
<h3>What occurs if there is a untimely end codon?</h3>
Thus, nonsense mutations occur when a premature nonsense or end codon is added in the DNA sequence. When the mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal. Consequently, most nonsense mutations result in nonfunctional proteins
<h3>What mutation motives untimely cease codon?</h3>
In genetics, a nonsense mutation is a factor mutation in a sequence of DNA that effects in a premature stop codon, or a nonsense codon in the transcribed mRNA, and in a truncated, incomplete, and normally nonfunctional protein product.

The biomolecule that would be the preferred dietary intake molecule the day before a long distance runner is scheduled to compete in an event is Carbohydrates. The answer is option B. Carbohydrates are considered as the base diet among athletes because it can give almost half of the energy needed especially in high intensity activities or sports. It is considered as a good fuel for athletes that can be easily replenished.
