Answer:
the concentration of the solute is lower inside the cell than outside it
Explanation:
This question depicts the process of ACTIVE TRANSPORT, which is the movement of a substance against concentration gradient, hence, requires energy input (ATP) to occur. In this case, transporting a solute from inside an animal cell to the extracellular fluid across the cell membrane always requires energy.
This is because the concentration of solute inside the cell is much lower than that of the extracellular fluid, hence, to move the solutes against this concentration gradient (low to high), energy in form of ATP is required.
Answer: It proposes that the entire double‑stranded DNA molecule serves as a template for a whole new molecule of DNA.
Explanation:
In semi-conservative DNA replication:
- a parent double-stranded DNA splits in two.
- Each strand serves as template, and then read by the enzyme, DNA polymerase, to ensure accurate synthesis of a new daughter strand for both
- the newly synthesized strand contains nucleotides that are complimentary to free nucleotides present in the parent strand.
Thus, because the parent double strand is retained in the newly synthesized DNA, this model is described as semi-conservative
