C O O liko mer 0 AS 6 0 O Paramecium -- Paramecia are quite large, straw-colored, slipper-shaped and move rapidly, and they are thus very noticeable. If there are Paramecia in your field of view you probably will recognize them immediately. Often, however, students do have difficulty both finding a Paramecium, and after they have found one, making it move slowly enough so they can study it at high magnification. The trick to finding a Paramecium is to scan the entire slide quickly using the scanning lens. Then, if you do not find one, make a new slide and search again. Often, Paramecia tend to move to the edges of the coverslip, and even "escape" the coverslip at its edges. The trick to slowing the Paramecia is to mix a drop of methyl cellulose with a drop of the cell culture, as…www ပိတ်ကောင်းဖော်မွန် following statements with appropriate words. TION 1.

Answer the following questions based on your observations. NO measurements will be taken on this day. a) Are the cut fragments showing signs of regeneration? b) How did you identify the regenerating portion?…Part B. Please turn in typewritten answers to the following questions 1. Asexual reproduction in diatoms occurs when the two valves move slightly apart and the cell divides in a plane parallel to the valves. A new valve is formed which nests within the parent valve. What happens to the average cell size in a population of diatoms reproducing in this manner? How has diatom life history evolved to resolve this issue of changing cell size? Explain. 2. Many benthic invertebrates produce planktonic larvae. Please provide a rationale for a meroplanktonic lifestyle. That is, what are the putative advantages of spending only part of the life cycle in the plankton? 3. Many species of zooplankton will undergo daily vertical migrations, spending the daylight hours lower in the water column and the evening hours closer to the surface. Please speculate as to why so many species display this common behavior.True or FalseS1: The body of the organisms belonging to kingdom protista is generally known as the thallusS2: Contractile vacuole is present in plant-like and animal-like protist
