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:
product rule
Explanation:
In Statistics, the product rule, also called the "Leibniz law", is a rule that allows the differentiation of products from differentiable functions. This rule says that the derivative of a two-function product is the first function times the derivative of the second function plus the second function times the derivative of the first function. This rule is often used in forked line and probability methods.
True.
I know this because it happened to my family and friends families. Sorry if it’s wrong
The behaviour of molecules in different phases of matter represents a balance between the kinetic energies of the molecules and the attractive forces between them.
All molecules are attracted to each other. At the same time, all molecules are in constant motion, and their kinetic energies increase with the temperature.
At very low temperatures, the kinetic energy of the molecules is low. The molecules cannot move fast enough to get away from the attractions of their neighbours. They are “glued” in place in a crystalline arrangement. The molecules are in the solid state.
At higher temperatures, the kinetic energy of the molecules is higher. The molecules will have enough energy to slide past their neighbours, but not enough energy to escape their attractions. The system is in the liquid state.
At very high temperatures, the kinetic energy of the molecules is so high that the molecules will be able to escape the attractions of their neighbours and move at will within the container. The system is in the gas state
I think they are different in that they have jaws. Rays are predominantly marine and are found in all the oceans. Many are slow-moving bottom dwellers. They include, Manta ray which is one of the most known type of rays, Spotted eagle ray (pacific ocean), sting ray among others. They are about 15 types of rays in the oceans. Sharks, Lampreys and rays, like all fishes they are aquatic, water-breathing vertebrates with a brain and spinal cord, fins, plate-like pairs of internal gills, and paired sense organs.
