I am doing an experiment on the effect of caffeine on euglena. I already started it and recieved euglena in AGAR. That made my project confusing b/c i didnt know how the AGAR affected the EUGLENA. It made the euglena hibernate. I observed the euglena after the AGAR EUGLENA BEING IN 2 HRS IN DISTILLED WATER, and few of the euglena were moving. Euglena is suppossed to be oblong, but most of them were circular and not moving much. Then i took the agar euglena( with an inoculating loop) and put it into 1% solution of caffeiene in distilled water.I waited 2 min and observed the euglena under a microscope, but they looked just like the euglena without CAFFEINE!! is it htat they are still hibernating, so they wont be affected by the caffeien? Also, ithink with caffeine, the euglena will form a cyst. HOw will i recognize the cyst when the euglena forms one? DOes the euglena become circular? Becuz alot of them are kinda circular rite now. Plez help b/c i need finish this...THANKS!!!!!

Doesn't this sound yummy?

Experts have long agreed that the fatal brain-wasting disease called Mad Cow is spread by the routine practice on industrial farms of feeding cows to cows---essentially turning natural herbivores into cannibals. (This practice of course is banned on organic farms.) Now a group of industry-friendly scientists have come up with a "solution" to the problem. Instead of discontinuing the practice of force-feeding bovine herbivores blood, manure, and slaughterhouse waste, scientists claim they have successfully genetically engineered a new cow that will not contract Mad Cow Disease, even when fed infected meat from Mad cows. Scientists have genetically engineered the cows to be born without normal nervous system prions, which go awry when an animal catches the disease. According to the researchers, the animals appear to be doing fine, so they apparently don't really need those prions anyway (even though they are there as a result of millions of years of evolution).

People are up to a foot taller on average than in the middle ages. This can easily be verified by doing some research yourself. Wouldn't this be considered as an evolutionary trait in humans?

I have found differing information when researching the habits of this butterfly.

2007-01-12 01:53:13 · 4 answers · asked by Anonymous

I know it lays eggs on the Alfalfa plant but there is no alfalfa around here, to my knowledge. I have to illlustrate and teach about the life cycle of this butterfly and the red clover is much prettier to paint but I don't know if it is a host plant. Are there any good web sites that show the life cycles of butterflies, clearly, so the pictures can be used as reference for natural science illustration?
