Describe the process that maintained a stable tasmanian devil population size before the appearance of dftd in 1996.
Vinvika [58]

Answer:

Prior to the appearance of DFTD, it was genetic variation and gene flow that were maintaining the population. Having more genetic variation and movement of genes between populations of Tasmanian Devils likely allowed them to avoid an inbreeding depression.

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.

What makes nekton swimming abilities different from plankton and benthos
Nitella [24]

Answer:

The nektonic organisms are those marine organisms that are found in almost every depth. These can move freely from one place to another in the ocean body due to its ability to swim. For example, Turtles, sharks, Fishes, and dolphins.

The planktonic organisms are passive swimmers, as they can move along with the ocean currents and are mostly found in the upper portion of the ocean body. For example, Diatoms and Rotifers.

The benthos is the bottom-dwelling organisms that cannot swim. For example, Bivalves, Corals and Sponges.

The nektonic organisms are different from the planktons and the benthos because the nektons can easily swim. They are constructed with such body parts that allow them to swim and migrate from one region to another region within the ocean water body. Whereas the planktons and the benthos cannot migrate easily and are considered as sessile organisms.
