atroni [7]

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.

which of the following shows the levels of organization in a multicell organsim from the smallest level to the largest?
zzz [600]

1. Organelles-. e.g. mitochondria, nucleus.

2. Cells- e.g. epithelial cells, palisade cells. 

3. Tissues- e.g. muscles, connective tissue.

4. Organs- e.g. heart, liver.

5. Organ systems- e.g. digestive system, circulatory system

This is because there are many organelles inside a cell and  a collection of same cells that creates tissues, a collection of tissues form organs, to carry out a particular function, and a collection of organs working together is an organ system. I think this is what they're after as I had a similar question a little while ago.
