Answer:
Because they are sterile
Explanation:
<em>Mules are considered to be a weak hybrid and not a separate species because they are sterile and cannot produce progeny of their own.</em>
Mules are hybrid products from two separate species - a donkey and a horse.
A species is generally defined as a group of organisms that are capable of breeding to produce fertile offspring. <u>Hence, in order for them to have the potential of being categorized as a separate species, they must be able to produce their own progeny but this is not the case. </u>

There are two classes of membrane transport proteins—carriers<span> and </span>channels<span>. Both form continuous </span>protein<span> pathways across the lipid bilayer. Whereas transport by </span>carriers<span> can be either active or passive, solute flow through </span>channel proteins<span> is always passive.</span>
<u>Pressure increases with depth </u>
Explanation:
Pressure increases with depth because the molecules at the deeper end are compressed by the weight of the above column of the fluid. Compression means there are more molecules of the fluid per volume in the deepest place than the surface. More molecules mean more pressure.
This is why divers need special gear when diving deep in the ocean to protect themselves form increased water pressure. In addition, the lowest atmospheric layers have the highest pressure because they are more dense and bear the weight of the above air column. This is why air pressure is a bit lower up the summit of a mountain than at its base.
