Answer:
C. About 18 percent of the variation in blood pressure can be explained by a linear relationship between blood pressure and caffeine consumed.
Explanation:
Here, r = 0.428
∴ We can say it will give a positive curve, as 0.428 indicates it is a positive correlation.
Though the amount of correlation is low, still it is positive and more than 0.4
So, nearly about 18% of the variation in the blood pressure can be observed by the consumption of caffeine water. As consumption of caffeine water and blood pressure is both increasing so we can say that r= 0.428 will give a positive linear curve.
The correct answer is an agricultural revolution.
Agricultural revolutions permitted communities to generate food, which would support huge populations. This permitted for the establishment of technology, like writing and reading. This provided civilizations an advantage over gather hunters.
The agricultural revolution of the 18th century created the path for the industrial revolution. Novel farming techniques and bettered livestock breeding resulted in enhanced production of food. This permitted an upsurge in population and increased health.
"B. organisms that use the same resource" is destined to cause the most competition between those organisms, since resources are scarce and almost always limited.
The correct answer is e.glycogen; breaks down into readily usable carbohydrates.
<span>
Animals store some glucose (smallest molecule into which a carbohydrate is broken down) in the cells of the liver. The energy of glucose is stored as glycogen. Glycogen is a very large, multi-branched polymer of glucose residues that can be broken down when energy is needed for the cells.</span>
Eukaryotic transcripts (mRNA) have to undergo capping and splicing before it can be translated.
<h3>RNA processing:</h3>
1. An RNA transcript is first produced in a eukaryotic cell as a pre-mRNA, which needs to be converted into a messenger RNA (mRNA).
2. The RNA transcript is given a 5' cap at the start and a 3' poly-A tail at the end.
3. The process of splicing involves cutting out some RNA transcript segments (introns), then joining the remaining segments (exons) back together.
4. Some genes have the ability to alternate splices, which produces various mature mRNA molecules from the same beginning transcript.
The introns not only do not contain the information necessary to construct a protein, but they also need to be cut off in order for the mRNA to create a protein with the correct sequence. An mRNA with extra "junk" in it will be created if the spliceosome fails to remove an intron, and the translation process will result in the production of the incorrect protein.
