psuedopod, ameba shaped, protists..pick one you like

Check for the optimum texture and pH for the grass.\n\n\nFor the amoeba,i guess it is contractile vacuole.

The spherical shape is the strongest against internal or external pressure.  Next comes a cylindrical shape with spherical end caps.  Next comes a cylindrical shape with indented end caps sort of like the bottom of  a champagne bottle.\n\nThe spherical shape also has the most volume for the surface area so less metal is needed to make the vessel.  \n\nIn other words, you get the strongest vessel using the least amount of material, with a sphere.

I think you're off...sorry. Caffeine accelerates metabolism of animals that have nervous system. It doesn't affect the cells, it affects the nervous system that controls the metabolic rate of, for example, mammals. It works pretty much teh same way as adrenaline.\nOn the other hand, euglena cysts don't have reduce metabolic rate: the dont have ANY metabolism going on. They're just a mass of molecules disposed in a perfect way that when triggered by the environmental condition, they start  working. Like a car motor. To do this, the euglena must in fact be very metabolically active in order to produce a lot of stuff and make a lot of changes to prepare for cysting. The stimuly are very specific: water and glucose. (and lack of water or glucose to form teh cyst). So i doubt that caffeine will affect, unless you put so much into the water that it becomes a poison, in which condition it may form a cyst (not by affecting the metabolic rate though)\nYou migh want to rethink your project and try to find out how much caffeine is pisonous for euglena and can it form cyst to protect itsefl from this condition?\nThe other thing about working with petri dishes: If it's a solid medium, nutrients will probably drop dow very fast, in which condition the euglena will form cysts. You won't be able to know how much the lack of nutrients made it unvulnerable to caffeine. Try to use a system that is more stable, like liquid medium, in which you can somehow trigger a cyst forming event. That way you will have more control.\nGood luck

The answer is either b or c.\nI recall that this is the gametophyte generation. I'll go with (b) because I also recall that it was a heart shaped structure.

a) isoceles\nb) hexagon\nc) hemisphere\nD) equilateral\ne) \nf)\nG) sphere or spherical\nh)\ni)\nj) scalene\n\nthese are the ones i know. next time, do your own homework!

Think I found the answer on-line, quoting:\n"It also has a red eyespot. Euglena gracilis uses its eyespot to locate light. Without light, it cannot use its chloroplasts to make itself food."\n\nfrom the site: http://www.fcps.edu/StratfordLandingES/Ecology/mpages/euglena.htm\n\nhope that helps

The parabolic structure is stronger than a circular strucure or dome.\n\n---Addition---\n\nLet's think in an egg. An egg has two different shapes in each end, one is more rounded like an hemisphere and the other is more like the shape of a paraboloid.\nIf you press the egg from both ends, the egg brakes always \nfrom the more rounded one, the hemisphere looking shape instead of the paraboloid looking end.

It is a triangular prism. It has 5 faces, 9 edges, and last but not least 6 vertices. There is your answer you have been waiting for this whole time!

It is not exactly round, just looks that way.\n\nSee webpage below for the correct shape.

An ameba. It is a single cell organism according to science book years ago. But I suspect the earlier answer as a virus is also correct.

the amoeba i guess, it is unicellular.the largest ones are 1 mm across

Sponges are Porifera; hydra are Cniderians.\n\nPorifera have body pores (ostia), canals and chambers that serve for passage of water. They also have choanocytes (collar cells) specialized cells that create water currents, as they are filter feeders.  \n\nCnidarians have stinging cells organelles called nematocytes or cnidocytes. They also have a nerve net with symmettrical and asymmetrical synapses.  They have a muscular system.

They are unicellular organisms. They can be found at the end of the winter, when they are most numerous, in fresh water. They will cover surfaces of aquatic plants or poles and wooden borders of ponds. If you like to study them you can scrape the brown growth with a flat piece of plastic. You can also use a sponge.

euglena are alga which use photosynthesis to produce their own  energy source, primarily, glucose.  cyanobacteria must occupy a biological host in order to survive and multiply.

Both being unicellular (no matter what anybody said), and generally autotrophic organisms... All protists are unicellular, and not all algae belong to Regnum Protista... Place of algae in Whittaker's 5 Regnums is not well explained, and multicellular algae belong to Regnum Plantae... If someone has better idea where to classify them they could make a career out of it...\nBut remember, most people still divide all the organisms into 2 Regnums: plants and animals...
