Answer:

When the required direction of transport is opposed to concentration levels, a cell <u>will </u> expend energy to force<u> ions</u> across its membrane.

Explanation:

If the concentration gradient is opposite to the direction of transport of minerals, then the cell will use energy to transport mineral ions from a lower concentration to a higher concentration. The most common process through which this happens is termed as the active transport.

The process of active transport is opposite to passive transport. In passive transport, molecules move from a higher concentration to a lower concentration.

How would being able to bring water into the gills when the mouth is closed benefit a bottom-dwelling shark or ray?
trapecia [35]

Answer:

The ability to bring water into the gills when the mouth is closed would benefit a bottom dwelling shark or ray, because it would allow them to be more discreet when in the process of catching prey and they would be able to stop swimming. Most sharks have to continuously swim or else they would sink, while being able to bring water into the gills when the mouth is closed would highly benefit them and allow them to stop swimming for a moment.

Explanation:

I am not 100% sure this is the correct answer, but I am currently doing a lab on this, so I am using the knowledge I previously had and online resources. I am pretty confident though.
