Answer:

e. All of the above are correct.

Explanation:

Active transport is a type of transport in living systems in which molecules/ions/substances are moved or transported against their concentration gradient i.e. from a region where the substance is LOW to a region which it is HIGH, across a membrane. Since molecules are transported across a memembrane against their concentration gradient, an energy input in form of ATP is needed to do so.

Active transport is used in living systems to transport out secretory products and waste material against concentration gradients, take up nutrients from the environment against concentrations gradients etc. Since ions are substance moved by active transport from a low region to high region, there is an imbalance in the intracellular concentration of ions, such as Na, K etc.

Since there is no equilibrium in the concentration of ions on opposite sides of the membrane, an electric potential is formed across the membrane i.e. one part of the membrane will be more positively charged than the other.

The diagram shows the thermohaline circulation, also know as the ocean's conveyor belt.

DanielleElmas [232]

Answer:

The statement that is true about red currents in the thermohaline circulation is that water in the red currents contain less salt (option A).

Explanation:

Thermohaline circulation is a concept used in oceanography, referring to the oceanic circulation that depends on factors such as surface heat and salinity, as well as the density gradient that they determine.

On a map, the different currents that are part of the thermohaline circulation are usually represented with blue and red lines, where:

The blue lines represent deep, cold, dense and higher salinity currents.
The red lines represent surface currents, warm, with less salt content, so they are less dense.

The red currents (see image) represented on the map have less salt content, compared to the currents represented in blue.
