Answer:

1) Movement to area of lower concentration: facilitated diffusion  . It consists in the diffusion of a substance through a membrane in favor of its concentration gradient, that is to say that there is movement from an area of ​​greater concentration to another of less concentration.

2) Movement assisted by proteins: both. In the facilitated diffusion the molecules must pass through membrane proteins. In active transport, the proteins involved are called pumps that normally use chemical energy.

3) Requires energy active transport: active transport makes use of energy for the movement of molecules because the movement is against a concentration gradient.

4) Sodium ion transport out of the cell: It is a type of active transport because it requires energy to allow movement against its concentration gradient, the ATP supplies the energy.

5) Glucose transport into cell: It is a type of diffusion facilitated through membrane proteins.

6) Movement across a membrane: both

Which is true of both DNA and RNA
maxonik [38]

Answer:

C. They contain sugars, phosphate, and nitrogenous bases

Explanation:

A. is wrong because only RNA is made up of single strands of nucleotides, while DNA is a double-stranded helix.

B. is wrong because DNA and RNA are examples of nucleic acids, not carbohydrates

D. is wrong because only RNA contains uracil, while DNA has thymine instead of uracil.

C. is correct because both DNA and RNA have sugar-phosphate backbones and nitrogenous bases. The difference between RNA and DNA is seen in their names--deoxyribo nucleic acid (DNA) vs. ribo nucleic acid (RNA). Ribose is a type of sugar, the same as found in RNA, while deoxyribose (in DNA) is the same except for not having an oxygen atom on the 2' Carbon (de-oxy = without oxygen).

What effect would decreasing water temperatures have on the cod population in the Georges Bank?
bixtya [17]
Due to the cold temperatures then More cod would be driven away from the Georges Bank. The scientific reason for this option is that c<span>older temperature will cause the concentration of oxygen to drop in the water and solubility will  increase with temperature.</span>
