RED TIDE:\nNot every plant poisoning is caused by a large, terrestrial plant. Several microscopic marine algae are notoriously poisonous to hapless humans who consume them in shellfish. \nThese Algae are tiny, single-celled plants that, like plants on land, capture and use the sun's energy to grow. The growth of algae is an essential life process, as it is the first step in transferring solar energy into aquatic food webs. The huge variety of marine algae are typically subject to annual cycles of growth & decay. These organisms thrive and multiply principally during the spring and summer, in response to increased light intensity and favourable levels of salinity & nutrients in ocean water. During the growth period, or bloom, each single algae cell may replicate itself one million times in two to three weeks.\n\nDuring the reproductive riot of the bloom, warm, shallow seawater tends to become discoloured by the sheer concentration of algae seeking the sunlight. This discolouration is a result of the various pigments the plants use to trap sunlight; depending on the species of algae present, the water may reflect pink, violet, orange, yellow, blue, green, brown, or red. Since red is the most common pigment, the phenomenon has come to be called Red Tide.\n\n\n2)DIVISIONS\nThe fungi kingdom is broken down into four phylums, the chytrids, zygote fungi, ascomycota, and basidium. The phylums are such:\n\nChytrids: Most scientifically inclined people assume that all the fungi were derived from an algal ancestor who lost its ability to photosynthesize. This then turned into to the flagellate fungi. A fungal ancestor then gave rise to the rest of the fungi, and usually this ancestor was assumed to be a member of the Chytridiomycota, a phylum which produced posteriorly, uniflagellated zoospores. The chytridomycota(chytrid) have the basic fungi key enzymes, cell walls made of chytin, and metabolic pathways that resemble the fungi's. They seem like the outcast of the fungi world, and are fungi because they are sort of like the rest of the fungi classes. \n\nZygote Fungi: Zygote fungi are terrestrial, which means they live only on land, usually on soil or decaying plants. One group of zygote fungi that live in the roots of plants is mycorrhizae. Another common zygote fungi is teh black bread mold, which absorb the bread's nutrients by spreading out on it, and extending hyphea in it. Zygote fungi have sporangia, which develop at the tips of hyphea. Haploid spores grow in the sporangium, and then are dispersed through the air. The reproduction will be talked about more extensivly in that section. Some zygote fungi can aim thier spores, and the picture on the left shows the spore being thrown by its sporangium at grass. \n\nAscomycota: Otherwise known as sac fungi, they can be aqueous, as well as terrestrial. The features that are importaint about this division is that they produce sexual spores in saclike asci. They reproduce asexually and disperse spores in the wind. They have a very long dikaryotic stage, in which they deveilop asci. \n\nBasidium: These are also known as club fungi, which have club-like tops. Typical mushrooms are an example of the club-like reproductive site. They decompose wood, and other plant material. The basidium have fruiting bodys called basidiocarps, which are the source of sexual spores. They sometimes attract flies

Sounds like a Math/Science type question to me. Why are you posting it here?\n\nBesides, I have the the slightest idea.

This is a calorimetry problem! There is an equation for it:       \nq = mc(change in temperature)\n\nq = the heat required \nm= mass\nc= specific heat \n\nAlso, write out the reaction and products.

I won 10 points!\n\nThis is pretty easy. Try to stump me with harder ones.

I know the answer is in my basic physics book.  I would have to look it up.  You should too.

Look up stuff like Arrhenius equations. I don't have my phys chem text book to hand.\n\nFor part two, I think it's D, as I'm fairly certain it's not any of the others.

This may possibly be the easiest question anyone has ever asked on this forum. If you can't figure this out yourself, you really need to do more homework!! BTW, that is one freakin' tall sheep!!

1.) do your own homework\n2.) this is the computer forum, not high-school chemistry.  Next time post to the right furom.

You are so smart - in fact, so smart that no one in THREE DAYS has even tried to answer your question.  Perhaps you can take this question and apply it to another realm:  \n\nhttp://antoine.frostburg.edu/chem/senese/101/index.shtml\n\nThis way you can get your homework done for you by people who know chemistry on a much larger scale... Answers is not here for homework completion
