Answer the following question given this paragraph: The second stage of photosynthesis takes place in the stroma surrounding the thylakoid membranes of the chloroplast. The reactions of this stage can occur without light, so they are sometimes called light-independent or dark reactions. This stage of photosynthesis is also known as the Calvin cycle because its reactions were discovered by a scientist named Melvin Calvin. He won a Nobel Prize in 1961 for this important discovery. Q: Which cycle is named after the scientist melvin calvin? Choices: - krebs cycle - melvin cycle - melcal cycle - calvin cycle A:
(A).
calvin cycle
Ques:Answer the following question given this paragraph: Elongation is the addition of nucleotides to the mRNA strand. RNA polymerase reads the unwound DNA strand and builds the mRNA molecule, using complementary base pairs. There is a brief time during this process when the newly formed RNA is bound to the unwound DNA. During this process, an adenine (A) in the DNA binds to an uracil (U) in the RNA. Q: What is the addition of nucleotides to the mrna strand? Choices: - insertion - elevation - axons - elongation A:

Ans:elongation
Answer the following question given this paragraph: Unsaturated hydrocarbons contain at least one double or triple bond between carbon atoms. As a result, the carbon atoms are unable to bond with as many hydrogen atoms as they would if they were joined only by single bonds. This makes them unsaturated with hydrogen. Unsaturated hydrocarbons are classified on the basis of their bonds as alkenes, alkynes, or aromatic hydrocarbons. Q: What type of hydrocarbons contain at least one double or triple bond between carbon atoms? Choices: - ionic - catalytic - saturated - unsaturated A:
unsaturated
