Answer:
Rotifers are specialists at living in habitats where water dries up regularly.
The Monogononta, which have males, produce fertilised 'resting eggs' which can resist desiccation (drought) for long periods.[11]
The Bdelloids, who have no males, contract into an inert form and lose almost all body water, a process known as cryptobiosis. Bdelloids can also survive the dry state for long periods: the longest well-documented dormancy is nine years. After they have dried, they may be revived by adding water. In this, and several other ways, they are a unique group of animals.[12]
Explanation:
The front has a ring of cilia circling the mouth. This gave the rotifers their old name of "wheel animalules". There is a protective lorica round its body, and a foot. Inside the lorica are the usual organs in miniturised form: a brain, an eye-spot, jaws, stomach, kidneys, urinary bladder.
Rotifers have a number of unusual features. Biologists suppose that these peculiarities are adaptations to their small size and the transient (fast changing) nature of its habitats.
Answer:
C. natural selection
Explanation:
Natural selection is when the organisms that have the better adaptation so they survive. In this case, the green was the better adaptation so they lived.
Carbon dioxide in the tissues is produced as the result of oxidation of glucose...
This carbon dioxide in process of respiration diffuse out of the tissues in form of molecular carbon dioxide and join with water forming carbonic acid ...
In lungs again carbon dioxide is separated and released out of the body...
The benefits are Beaches are better protected against erosion.
Trenches created in the ocean encourage species growth.
WhatWhat are the advantages and disadvantages of beach nutrition?
Since nutrition just reduces the consequences of erosion and does not address its origins, it is usually a recurrent procedure. An agreeable setting lengthens the time between nutrient projects, cutting costs. On the other hand, a high rate of erosion might make nutrition unprofitable.
Sea turtles and rare and endangered birds alike depend on healthy beach and dunes systems. Important wildlife habitat areas that are endangered by erosion are provided by maintaining nourished beaches.
