What is 100 ml in weight in ounces?
The weight of 100 ml of a substance will vary depending on its density. However, for water, which has a density of approximately 1 g/ml, 100 ml would weigh approximately 3.5 ounces.
FVB mice are often used in production of transgenic mice due to their excellent reproductive capabilities and nurturing characteristics. In addition, FVB mice have large embryos which makes them easier to manipulate for microinjection of transgenes.
what is an controlled variable. we need to know it for our science proformance asscement!!! From a friend in need!
If two glasses of water are at the same temperature the average is?
The average would be the same temperature as the two glasses of water.
Using the following formula for finding the average temperature this is proven.
(Temperature of glass one) + (Temperature of glass two) / (number of glasses) = Average
Who is Dr Fred Whipple and explain his hypothesis?
Whipple came up with the "dirty snowball" concept of comets; that the head of the comet is primarily ice and frozen gasses bound together by dust, gravel and rocks. This explains the nature of the "tail" of the comet; as the frozen gasses sublimate away (change from solid to gas, without an intervening liquid state) the gas is carried away by the solar wind and by pressure of the sunlight itself.
What is an experimental group?
An experimental group is the group that gets changed. For example if there was a disease and there were 2 different products to cure it, the group, let's say group A, with the product that works, would be the experimental group. This is because it is the group with the product that has been changed for the experiment. The other group, group B, would be the control group because it has the product that stays the same as if nothing ever changed, because that product doesn't work.
How will repeating an experiment make the results more accurate?
because then you realize what you did wrong and fix it.
constant speed
Why is there less resistance on a smooth surface?
Because friction is less on smooth surfaces.
Smoother the surfaces, lesser the friction.
Can girls produce more electricity when measured than boys?
-- The quantity of energy present has nothing to do with whether or not
it's being measured.
-- The only way that anyone has of producing electricity is by cranking a
generator. Males, being physically larger and stronger on the average, are
probably statistically out in front of females in that regard.

What is a good science fair project on human psychology?
I did 2 science fair projects. Do boys or girls have better lung capacity? Or how has more accurate sences boys or girls?
