Sophie [7]

Answer:

C.  Cnidarian tentacles have stinging cells, but Bryozoan tentacles are covered with cilia.

Explanation:

Cnidaria and Bryozoan, both teh phylum are classified under kingdom Animalia that contain aquatic animals found both in freshwater and marine environments.

They both use tentacles for feeding but there is diffference between there tentacles and feeding process.

Cnidarians tentacles are conist of stinging cells in the tips, which are called cnidocytes and a coiled thread-like stinger, called nematocyst. These stinging cells and nematocyst helps to capture and subdue prey. They feed over plankton or animals larger then them.

Bryozoan tentacles are covered with cilia and form an "O" or "U" shaped fold called lophophore, which helps to feed by sweeping the surrounding water. They generally feed on plankton, nudibranchs (sea slugs) and sea spiders.

Hence, the correct option is C.

Explain the role of enzymes as biological catalysts that lower the activation energy of a reaction.
tia_tia [17]

Answer:

Enzymes are one kind of protein which functioning as catalyst  that speed up reactions by lowering activation energy.Enzyme accelerate a reaction without altering its chemical equilibrium.

Explanation:

Energy which is required for  start a biochemical reaction is called activation energy.Activation Energy helps to jump and start a thermodynamically favorable reactions.

Enzymes can  many  way to its activation energy.

1. The enzyme may hold the substrates in such a way as to distort the substrate bonds closer to their form in the transition state. This reduces the amount of energy needed to complete the transition.

2.Enzyme create a charge distributor which opposite of transition state his lowers the energy of the transition state and decreases the activation energy.

3.The enzyme may reduce the reaction entropy   by bringing substrates together in the correct orientation to react.

4. The enzyme may provide a completely different chemical pathway for the reaction. It may form new bonds in the ES complex that would be difficult to form without the enzyme.
