The biochemical analysis of different chlorophyll pigments in plants would be most useful in determining <span>D. which plants might have a common ancestor.
The field of biology that deals with the similarities between these plants is called comparative biochemistry. If these plants have similar DNAs, then they are more closely linked in evolutionary terms, and thus it is quite possible they have the same predecessor.

Answer:
Steps 1, 3, and 10 of glycolysis are bypassed in the gluconeogenesis pathway. These steps are spontaneous and irreversible Since the two pathways do not share all the steps this means they are not the irreversible, thus presenting no thermodynamic barrier to the concurrent occurrence of the pathways.
Explanation:
Sorry I am late on answering the question, if u don’t know what it is still, the answer I believe is D!
Answer:
The kidneys help control acid-base balance by excreting hydrogen ions and generating bicarbonate that helps maintain blood plasma pH within a normal range. Protein buffer systems work predominantly inside cells.
Explanation: or
How is pH regulated in the body?
The lungs control your body's pH balance by releasing carbon dioxide. Your brain constantly monitors this in order to maintain the proper pH balance in your body.
The kidneys help the lungs maintain acid-base balance by excreting acids or bases into the blood.J
Answer:
C.Never swims fast
Explanation:
RacerX and Speed protein need to bind to each other for the cilia to beat faster which would make the protozoan swim faster. However, Speed needs to be phosphorylated to be able to bind to RacerX. Thus, phosphorylation of Speed is necessary for the fast movement of cilia.
Threonine residue is phosphorylated in Speed protein. It occurs on its side chain through the formation of phosphoester bond. Apart from threonine, phosphorylation can take place on serine and tyrosine side chains again through the formation of phosphoester bond. It can also occur on histidine, lysine and arginine by formation of phosphoramidate bonds.
Since, alanine can not form any of these bonds it can not be phosphorylated. Hence when threonine is substituted with alanine in Speed protein, it can not be phosphorylated. Racer X wont be able to bind to Speed and cilia wont beat faster. As a result the protozoan will never swim fast.
