I am doing a biology lab were seeds are grown in the dark and light. Seeds grown in the dark become longer but light grown seeds develop more biomass over time. I get all that stuff. But how then would you define growth?

Ok so the question is Can plants grow in a dark environment with only a small amount of sunlight? This is my son's project. So we did the project. Put 2 plants in boxes with a small hole at the top and put the 3rd plant in the light. A&B (the plants in boxes grew faster) and C (the one in the sun ) grew a little slower, but was definetly in better condition. ( I know this is because clorophyll absorbes energy from the sun which gives the plants it's green color). The other 2 in the boxed grew taller (trying to reach for the light and climbed out of the top of the box) although the stems are pale. So can the plants still survive with only a small amount of light or will they eventually die? Best answer gets 10 pts

im doing a bio project that was give out yesterday. i have everything done except for 6 questions. it sounds like a lot but its nothing compared to what i did. The questions are about microscopes. I missed that lesson and i told my teacher but she said too bad.

so i come to your help nice people, please help me with these 6 questions.

1. Locate the diaphragm under the stage of the microscope. Move it and record the changes in light as you do so. (there are 5 intesities, 1 lowest - 5 highes)

2. Why is the correct use of the diaphragm important?

3. A penny is an opaque object. Why can't you observe such opaque objects readily without a compound microscope.

4. What is meant by resolution with respect to the microscope?

5. Why must one avoid the coarse adjustement knob to focus under high power?

6. Why is the resolving power just as important as mignifying ability in a microscope?

7. Duz resolution increase wit an increase in magnific when using a light microscope?

I realize that people are against cloning just to retrieve stem cells, but how can they argue so vehemently about the subject when most do not even fully comprehend it? Stem cells are cells which are unspecialized. That is to say they can develop into any of the 220 different types of cells in your body. Embryonic stem cells can only be found within the first 10 days after fertilization and removing them means immediate death for the embryo. The other type of stem cells, called adult stem cells, exist in everyone, but can only differentiate into certain types of cells. That's right, everyone has stem cells in them, which, by using newly developed techniques, could be cultured to produce living tissue which could be replaced into the body. Stem cells and, obviously, stem cell research can only result in cures for diseases such as Alzheimer's, Parkinson's and a ton of other of conditions. So why is everyone so against stem cell research when it can only do us good?

Or just use a real uterus someone donated in surgery, most likely after death, (in a car accident or something like that so it's healthy to have it).

Science teacher, yes, all of my equipement was sterile. All your help would be much appreciated. ( This bacteria that is dissolving the agar is very oderous as well. I have sealed it in a ziplock bag.)

When I refer to stopping source, I mean the "parent" of all sources. This seems to be illogical and self-contradictary to many scientific thinkers.
