Answer: ADP ( adenosine diphosphate) is a lower energy molecule, which is converted to ATP ( adenosine triphosphate) by the addition of one high energy phosphate group.
This is an endergonic process as it requires energy.
ATP thus formed in this reaction is a high energy molecule as it stores large amount of energy, which is present in the phosphoanhydride bond ( formed between phosphate).
The reaction can be written as-
ADP + Pi → ATP
Answer:
a. Blood vessels are constricting causing greater peripheral resistance.
Explanation:
Peripheral vascular resistance means the resistance in the circulatory system that is used to control blood pressure and the flow of blood. When blood vessels constrict, there would be an increase in systemic vascular resistance. When blood vessels dilate, there would be a decrease in systemic vascular resistance.
Answer:
Uracil
Explanation:
Like DNA, RNA is made up of nucleotides called ribonucleotides. However, unlike DNA, RNA contains the sugar ribose instead of deoxyribose and the base uracil instead of thymine. RNA also contains of only one polynucleotide chain. Uracil is a type of nitrogenous base that is replaced by thymine during the formation of RNA.
Hey, I believe your answer would be D. Sugar ribose and the base uracil. I believe this is the answer, because RNA consists of sugar ribose, adenine, guanine, cytosine, and uracil.
Your first option is incorrect, because that's DNA. Where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.
Your second option is also incorrect, this is because sugar deoxyribose is in DNA, and uracil is in RNA. These two do not make sense together.
Your third option being incorrect, because sugar ribose is in RNA, but not the base of thymine. RNA consists of uracil, not thymine.
Lastly your fourth option being correct! This answer is correct, because both sugar ribose, and the base uracil are in RNA!~
Answer is D. Sugar ribose and the base uracil.
