What part of the rotifer is responsible for crushing food?

Biology

frozen [14]2 years ago

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:

i) Glucose

ii) β(1-4) glycosidic bonds.

iii) Oxygen

Explanation:

Cellulose is an important structural carbohydrate found in plants. It forms a major component of the plant cell wall.

Cellulose is a polysaccharide formed by monomers of glucose.  These glucose monomers are joined together by covalent bonds called β(1-4) glycosidic bonds, which means that the 1st carbon of one glucose is bound to the 4th carbon of the next glucose. To make this arrangement,  every other glucose molecule in cellulose is inverted, which you can see in the diagram.

Glucose monomers contain carbon, hydrogen, and oxygen only. If you look at the pattern of the molecule (remembering every second glucose is inverted), you can see that Z must be O.

The functional group denoted by Z is oxygen. The OH groups on the glucose from one cellulose chain form hydrogen bonds with oxygen atoms on the same or on another chain, holding the chains firmly together and forming very strong molecules - giving cellulose its strength.

Which is NOT a characteristic of a plant? multicellular eukaryotes have chloroplasts mobility
murzikaleks [220]
<span>Among all choices, mobility is not a characteristic of a plant. Plants are multicellular organisms. They have organelles inside their cells and thus they are eukaryotes. Chloroplasts are organelles that are found in plant cells and they have an important role in the process of photosynthesis. However, plants cannot move from place from place like animals.</span>
