 B. Make sure the letter U is substituted for the letter T.
C. Make sure that A matches U and that C matches G.

The right answer are B (it means the letter U will replace the letter T) and C.

RNA (ribonucleic acid) is obtained from DNA through transcription.

RNA is complementary to the template strand of the DNA (antisense strand), according to Watson and Crick pairing rules (AU / T and CG) and is therefore identical to the coding strand of the DNA (sense strand), the riboses and uraciles (present only in RNA).

goldenfox [79]

Answer:

a. PGA down, RuBP up

Explanation:

RuBP, also known as Ribulose-1,5-bisphosphate is a molecule that assist in he fixation of carbon dioxide in the Calvin Cycle or light independent reaction of photosynthesis.

RuBP is combined with carbon dioxide using the enzyme known as rubisco to form an short-lived intermediate product which divides to form two 3-carbon molecule structure known as 3-phosphoglycerate.

<em>If the concentration of carbon dioxide is suddenly reduced, it thus means that the rate of production of 3-phosphoglycerate will reduce as carbon dioxide becomes a limiting factor. Hence, 3-phosphoglycerate's  concentration will reduce while more RuBP will become available as a result.</em>

The correct option is a.

Why is the phloem in a leaf important to the roots of a plant apex?
Nana76 [90]

Answer:

The correct answer will be- phloem transports photsynthetic products to the roots

Explanation:

Phloem is the vascular tissue which specializes in transporting the solute molecules like sugar in the form of sucrose to in the plants.

The phloem connects the photosynthetic organ (Leaves)  to non-photosynthetic organs (stem and roots) of the plants by transporting the photosynthates or sucrose to various parts.

Since the roots also need the energy to perform metabolic functions so need the photosynthates to synthesize the energy molecule. They receive the photosynthates from the phloem.

Thus, phloem transports photosynthetic products to the roots is the correct answer.
