Answer:
B. often use tube feet to move around in their environment
Explanation:
Tube feet are tiny tubular projections of echinoderms on the underside (oral side). They are a member of the echinoderm water vascular system.
Tubular feet are used for feeding, breathing and shifting. They are arranged around the sides, in grooves. They work by hydraulic pressure. They are used to transfer food in the centre to the oral mouth, and may stick to surfaces. Tube feet allow certain animals to stick and travel slowly to the ocean floor. for example starfish uses tube feet for the above functions.
Hence, the correct option is B.

Answer:
True
Explanation:
<u>The discipline of microbiology has to do with the study of microorganisms - tiny organisms that cannot be seen with the ordinary eyes except with the microscope.</u>
<em>Within the cells of microorganisms just as in every other cell, various biochemical processes take place in order to ensure the continued viability of the cells. Genetic information are also passed on from parent to daughter cells during the process of reproduction or cell division.</em>
Hence, the field of microbiology is associated with both biochemistry and genetics.
False in order for an ecosystem to survive there has to be some sort of competition. for example, if there were no sharks to eat little fish the little fish would over populate and then the little fish would run out of food which then means that whatever the little fish ate is now extinct and so on hinting the food chain's name. If it wasn't for competition nothing would survive
I think it is B. biome
Because biome means a large area dominated by characteristic plants and animals, such as a rain forest, desert, or tundra.
