Andrews [41]

Answer:

Facilitated diffusion in a cell has a limited amount of carrier and channel proteins, wherein if all are being used or saturated, can't transport the substances outside in to the cell, leading to the plateau of the substance.

Explanation:

In <u>low concentrations</u> of the substance outside the cell, <u>facilitated diffusion behaves like simple diffusion</u>, carriers and channels are not all used up. But in instances of <u>high concentration of the substance</u> outside the cell, <u>all the carrier and channel proteins are occupied</u> with the said substance. So <u>even if we increase the concentration of the substance, it will not increase the rate of diffusion.</u>

Why is phenotypic variation necessary for natural selection
Hitman42 [59]

Answer:

Phenotypic variation is the variation which appears in the phenotype or morphology of the organism. Natural selection is the mechanism of evolution in which the adapated organism to the environment is selected or highly favoured during the course of evolution.

A phenotype is the results of the genetic change which to be established in a population has to be passed on to the generation.

Since variation in phenotypic traits allows the organism to leave indifferent circumstances therefore phenotypic variation proves essential condition to natural selection.

In coral reefs, clownfish live unharmed among the poisonous tentacles of sea anemones. The sea anemones protect the clownfish fr
slava [35]

Answer:

The sea anemone and the clownfish live together in a type of symbiotic relationship called mutualism, where both species benefit from the other. The sea anemone offers the clownfish protection and leftover food

The anemone's tentacles provide the clownfish with protection from predators, while the clownfish chase away butterfly fish that would eat the anemone. ... Sea anemones can do very little to control the flow of water across their bodies, and they rely on local currents to bring in oxygen and nutrients.Clownfish perform an elaborate dance with an anemone before taking up residence, gently touching its tentacles with different parts of their bodies until they are acclimated to their host. A layer of mucus on the clownfish's skin makes it immune to the fish-eating anemone's lethal sting.Instead, both species have evolved behaviors that help them avoid being eaten while they graze for benthic algae. Butterflyfish typically swim in pairs near a particular clump of coral. ... An anemone robbed of its clownfish guards will quickly fall prey to the voracious butterflyfish.
