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.
It is important because you need vitamins and minerals from them e.g. Scurvy no vitamin c
Answer: The noble gases are a group of chemical elements that make up Group 18 on the periodic table. These gases all have similar properties under standard conditions: they are all odorless, colorless, monatomic gases with very low chemical reactivity.
Answer:
Which substance has a high albedo? B) White Sand
Explanation:
The albedo is the amount of energy that is reflected by a surface. It is determined by the refletivity of that surface. Albedo can range from 0 (no reflection) to a value of 1 (100% reflection). Generally, dark surfaces have a low albedo and light surfaces have a high albedo. Liquid water is considered to have a low albedo, like dark rock and rich soil.
Answer:
What is a Global Climate Model? A global climate model (GCM) is a complex mathematical representation of the major climate system components (atmosphere, land surface, ocean, and sea ice), and their interactions. Earth's energy balance between the four components is the key to long-term climate prediction.
