Answer:
About composition of water and organisms that lives there.
Explanation:
scientists might be able to learn about the composition of seawater that was present millions of years ago if we study those stones that comes in contact to that ancient seawater because the traces of particles still present on it. This study provides valuable information about ancient times of earth and its natural resources. These rocks also provides animals that were present in that sea water at that time.
I found the attached image on the internet and I believe it has the tiles referred to on the question.
As we can see on the image, the A-site, P-site, and E-site are represented. The A-site is occupied by the tRNA linked to the growing peptide chain. The P-site is the one occupied by the tRNA that works accepting the growing protein for peptide bond formation.
Firstly, the protein is formed, it is the
first tile from the left.
Then, the
first tile from the right is where the Leu is formed.
On the
second tile from the right the Leu is then added to the protein.
The process is then repeated again as there are two cycles of elongation adding a Leu in each of them:
third tile from the right,
third tile from the left,
second tile from the left.
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.
