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.
The scientific method is a problem-solving approach used in Biology and other scientific disciplines. This method has five basic steps which help scientists test their hypotheses. The first step of the scientific method is to make an observation. In this particular example, the scientist observes probably that salt has chemical and physical properties which could affect the life cycle of bacteria. The second step would be to ask a question and that would be to ask whether salt indeed has any effect on that particular type of bacteria that he/she studies. The third step would be to form a hypothesis and that would be to state that the specific bacterial type will be strongly affected by the salt. The fourth step would be to predict that if the scientist exposed this bacterial type to a salty environment, the bacteria would not survive. The fifth and final step is to test this prediction and if the bacteria do not survive, then the scientist can conclude that salt affects this bacterial type.

Answer:
This question is incomplete
Explanation:
This question is incomplete but the keys words in the question provides an idea of what the completed question is.
There are two types of nucleic acid; ribonucleic acid (RNA) and deoxyribonucleic acid (DNA).
They are both made up of ribose/pentose sugar, nitrogenous base and phosphate group.
The ribose sugar of the DNA is one oxygen less than the ribose sugar of the RNA hence the reason for the name "deoxyribose".
There are five nitrogenous bases namely; adenine, thymine, guanine, cytosine and uracil. They both contain adenine, guanine and cytosine; however, the DNA contains thymine while the RNA contains uracil. Of the five bases, adenine and guanine are the purines (have a double ring structure) while the rest are pyrimidines (have a single ring structure).
The phosphate group here is negatively charged
<h2>Henrietta Discovery </h2>
Henrietta Swan Leavitt discovered cepheids in 1908 during the investigation of different stars in the clouds. She published it by working more on it in 1912 and died in December 1921. This discovery was so important in the society in which she lived because the cosmologist of America was known for this discovery of Cepheids which is a relationship between period, luminosity and quivering stars which changes in light.
