Answer:
False.
Explanation:
Mars is the planet we are most likely to colonise due to the signs that there may have been some sort of life there before.
You will feel the s-wave 12.4 seconds after you felt the p-wave.
<h3>
How to find the difference in time?</h3>
The waves must travel 250 km, we know that the p-wave travels with a velocity of 6.3km/s. The time it takes to travel that distance is given by:
250km/( 6.3km/s) = 39.68s
At this point is when you feel the p-wave.
The s-wave travels at 4.8 km/s, than it will take:
250km/(4.8km/s) = 52.08 s
The difference in time is:
d = 52.08s - 39.68s = 12.4 s
This means that you will feel the s-wave 12.4 seconds after you felt the p-wave.

<span>The answer is valves. One </span><span>feature that the entrances and exits to the heart need in order to maintain this flow pattern is the valves. E</span><span>ntrances and exits to the heart may need valves in order to maintain this flow pattern. There are valves that control blood flow to the ventricles, and valves that control blood flow out of the ventricles.</span>
Sickle cell anemia is persistent in the tropics because those with sickle cell anemia cant contract the malaria virus because of the shape of their blood cells, and this is advantageous in the tropics where there are more malaria cases. So those with sickle cell anemia live to pass on their genes.
There are two explanations for this phenomenon: phosphorylation of the protein X in the heart activates its function (Option C) or phosphorylation of the protein X in the kidney and the brain deactivates its function (Option D). Therefore, both Option C and Option D are correct.
- Phosphorylation is a posttranslational protein modification that is capable of activating or deactivating protein function.
- Phosphorylation alters the three-dimensional structure of a protein, thereby modifying its function (i.e., activate or deactivate the target protein).
- Phosphorylation occurs at specific amino acids (e.g., serine and threonine residues) of the target protein.
- Moreover, mRNA splicing (RNA processing) occurs before the protein state, it is a transcriptional process. This process consists in removing the non-coding regions or 'introns' from pre-mRNA and subsequent joining protein-coding regions or 'exons' to enable the translation of the mRNA into a protein.
- In consequence, in this case, it is possible that 1-phosphorylation of the protein X in the heart activates its function, or 2-phosphorylation of the protein X in the kidney and the brain deactivates its function. Therefore, both Option C and Option D are correct.
