icang [17]3 years ago
3 0
  • Oxygen cycle is the cycle which maintains the level of oxygen in the atmosphere.
  • Oxygen from the atmosphere is used up during combustion, respiration and in the formation of oxides of nitrogen.
  • This oxygen is returned to the atmosphere by lithosphere.
  • This forms the oxygen cycle in nature.

Hope you could get an idea from here.

Cyanide is a poison that limits the ability of an animal cell to manufacture ATP. In a cell containing a small amount of cyanide
Naily [24]

Answer:

D. Diffusion

Explanation:

The process of diffuse transports the substances in the direction of their concentration gradients. Diffusion of substance from the region of their higher to that of the lower concentration does not require any energy. Being a passive process, diffusion can be carried out by a cell irrespective of the status of its ATP supply. Therefore, an animal cell containing a small amount of cyanide can transport substances by diffusion.

What part of the body uses active transport to take up nutrients after concentration has reached equilibrium
jekas [21]

The villi of the small intestine use active transport to take up nutrients after concentration has reached equilibrium.

<h3>What is Active transport?</h3>

Active transport may be defined as the process that occurs against the concentration gradient and is mediated by carrier proteins. Metabolic energy is used to move ions or molecules against a concentration gradient.

During the process of digestion, the villi in the small intestine enthrall the soluble nutrients gradually. Over time, the concentration of nutrients in the villi acquires an equilibrium with the concentration in the gut. Until here, the nutrient uptake is carried by the process of passive diffusion.

But after attaining the equilibrium, the nutrient uptake is carried by the process of active transport.

The complete question is as follows:

What part of the body uses active transport to take up nutrients after concentration has reached equilibrium?

  • Lungs
  • Stomach
  • Small intestine
  • Liver

Therefore, the correct option for this question is C, i.e. small intestine.

<span>Apart from their habitats, Bacteria and Archaea differ in cell wall structure and membrane lipid composition. All bacteria have peptidoglycans in the cell wall whereas the archaea do not. Both also are different in RNA polymerases and thus in their protein synthesis. </span>
