Answer:

When the molecules are too large.

Explanation:

Facilitated diffusion refers to the passive transport of substances down the concentration gradient via specific transport proteins present in the membrane. The large, polar, charged substances and ions cannot pass through the small spaces present between hydrophobic tails of membrane phospholipids. The transport proteins transport these substances in energy independent manner.

<h2>Diffuse co-evolution </h2>

Explanation:

The term ‘diffuse co-evolution’ was given by Janzen in 1980 to describe the idea that selection on traits often reflects the actions of many community members, as opposed to pairwise interactions between species

The idea was further clarified by Gould in 1988 by focusing on a variety of ecological and genetic mechanisms that might lead to diffuse co-evolution in response to selection from multiple species

Diffuse co-evolution as a whole can be defined as when selection imposed reciprocally by one species on another is dependent on the presence or absence of other species

In the given example panic grass can live only when the fungus protuberata is present and for Curvularia protuberata to colonize Curvularia thermal tolerance virus must be present so there is a web of multiple species where one species is dependent on other species and that other species in turn is dependent on different species hence referred to as diffuse co-evolution

Select the true statements about the electron transport chain.
almond37 [142]

Answer: A. In the electron transport chain, a series of reactions move electrons through carriers.

B. The products of the electron transport chain are H2O and either NAD or FAD.

E. The electron transport chain is a series of oxidation-reduction reactions that occur in the inner mitochondrial membrane.

Explanation:

the best suitable statement is it transfers energy stepwise from one compound to another, The electron transport chain is a series of proteins and organic molecules found in the inner membrane of the mitochondria. Electrons are transferred from one member of the transport chain to another in a series of redox reactions.
