Where you able to find the answer
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.
messenger RNA (mRNA) carries a transcript (copy) of the DNA's instructions out of the nucleus to the cytoplasm where it attaches to a ribosome.
transfer RNA (tRNA) begins to read (translate) the information on the attached mRNA and corresponding to this information, fetches the appropriate amino acids from the pool of free amino acids in the cytoplasm, and brings them to the ribosome where they are linked into a chain or polymer forming the primary structure of the desired protein.
Answer:
The correct option is D.
Explanation:
Protein generally are very sensitive macro molecules; they have specific temperatures and pH that are ideal for their operations, this is especially true for proteins that act as enzymes in biochemical reactions.
There are four different types of structures that a protein can assume, these are primary, secondary, tertiary and Quaternary structure. The structure of a protein determines the kind of function it can perform.
There are some factors that can destroy the structure and functions of proteins, these include excessive heat and pH. A protein is said to be denatured when its secondary and tertiary structure have been disrupted or destroyed. Denaturation does not affect the primary structure of the protein, thus, the peptide bond remains intact.
Denaturation is usually temporary and can be reversed if the factors that cause denaturation is removed, this process is called RENATURATION. Renaturation process allow the protein to refold and resume its functions. But sometimes, denaturation can be permanent and irreversible leading to permanent loss of protein functions.
As an organism evolved an ability or physical characteristic, another organism which evolved the ability to mimic that trait would have a higher chance of survival and could pass on its genes
