Question

1. wastes exit the paramecium through what? 12. what is the function of the trichocysts? 13. compare the endoplasm to the ectoplasm. 14. define avoidance behavior. 15. where do paramecium live?

Explanation:

1. Paramecium expels wastes through the cell - membrane via diffusion or exocytosis.
2. Trichocysts in paramecium are used for defense against predators and capturing prey.
3. Endoplasm is the inner, more fluid part of the cytoplasm with organelles, while ectoplasm is the outer, more gel - like layer providing structural support.
4. Avoidance behavior is an organism's response to move away from harmful or unfavorable stimuli.
5. Paramecium lives in freshwater environments like ponds, lakes, and slow - moving streams.

Answer:

1. Cell - membrane.
2. Defense and prey capture.
3. Endoplasm is inner and fluid with organelles; ectoplasm is outer and gel - like for support.
4. Movement away from harmful stimuli.
5. Freshwater environments such as ponds, lakes, and slow - moving streams.
