The answer
is arthropods have had more time to co-evolve with land plants than have
vertebrates. Analysis of genes shows that their sequences are quite similar,
and these sequences differ from those of the lophotrochozoans and
deuterostomes. Between the annelids and
arthropods will probably be viewed, in retrospect, as an instance of an
evolutionary relationship that modern scientists had ʺset in stone, ʺ now
having crumbled.
Answer:
(a) an aquaporin
Explanation:
An aquaporin is a water channel which forms a pore in the cell membrane and facilitates the movement of water. Aquaporin is an integral membrane protein (permanently attached to the membrane) that enables the in and out flow of the water. This channel also prevents the passage of ions and other solutes, so it cannot change the voltage. There are four types of aquaporins, and they are mostly found in the kidney with the function of water reabsorption.
Answer:
The financial costs for the farmer would be lowered.
Explanation:
Answer:
A. They eat nitrogen-containing compounds found in the soil.
Explanation:
Animals get the nitrogen they need by eating plants or other animals that contain nitrogen. When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use.
Yes, fish can sleep! Fish do not have eyelids to close, so they sleep with their eyes open. Depending on the species, fish can sit on the floor of a bowl, for example, to sleep. Others drift close to the bottom.
