Science & Mathematics - 11 December 2006

I know how to factor Quadratic Equations that do not have a coefficient in the first part. The 2x^2 is what's messing me up. A friend told me you multiply the first coeffecient by the last constant (2x3 = 6) and find two terms that multiply to 6 and add up to 5. It ends up wrong.

This isn't necessarily a question...just a shoutout to Ruby the Tiger at Mill Mountain Zoo in Roanoke, Virginia. Ruby was euthenized this last weekend (she was ailing and elderly) and we are all going to miss her dearly. So, post your thoughts here about Ruby...a good friend to the Roanoke and Valley region.

30.A _________________ is a picture of chromosomes. Doctors or scientist arrange the chromosomes into like pairs. The last pair is the sex chromosomes. This picture can show the sex of the person. Male’s last pair look like ______ and female’s last pair look like _______.
31._________________ is a genetic disorder where the individual has an extra chromosome that is similar to the chromosomes in the 21st pair. The individual is mentally retarded and sterile (unable to reproduce).
32.Gregor Mendel discovered the laws of dominance and recessiveness. A ______________gene will “mask over” or “over shadow” the outcome of a _______________ gene.
33._________________is a term used to express the actual DNA make up of the gene. In the study of genetics we use letters to represent this. Capital letters represent dominant genes and lower case letters represent recessive genes. An example could be TT, Tt or tt.

For the theory part of my lab, we are to find the theoretical slope of the height at which a Hotwheels car rolls down a ramp versus the distance the car travels horizontally after it reaches the bottom. I have the actual slope from a graph I constructed, but I don't know how to find it theoretically. Someone told me it was height = the coefficient of friction times distance, but I don't know if it is right. If someone could just help me find an equation, that's all I need. Thanks in advance.

So i got this homework and i need to do a karyotype. The teacher gave us the chromosomes and i took the ones that look like each other and put them in pairs and i got 47 chromosomes, i think the person has an extra X put how can i know which one is it, how can i defferentiate the X chromosomes form the others?

If so, would you mind answering a few questions? I'm supposed to do an interview and thought I'd try it out here.

1. What is the next step in space exploration?
2. How will we come up with a new means of propulsion?
3. What do you think of NASA's plans to build a moon base?
4. When do you think space tourism will become available?
5. When will humans reach Mars?
6. Do you think we will ever colonize Mars?
7. When will humans reach another star system?
8. Why have people lost interest in space travel and exploration?
9. Why do you think space travel and exploration is important?
10. Where do you see the space program in 50 years?

Thanks for your help.

** Bashing will be reported. Please answer on scientific basis, NOT according to your beliefs. Scientific, realiable links are appreciated concerning these issues:
- Is it genetic or nurtured (Results from something that happened in your life?)
- Does it exist in other species?

Thanx in advance.

I know that the individual molecules just bob up and down. What makes the wave as a whole move outward, and not say inward?

I mean, since the edge of a wave is a wavefront, what is preferred about the outward direction, for the wave to propagate. How does a water molecule bobbing 10 feet away from the stone know from which direction it got the energy to bob up and down?

Since all the water particles are moving perpendicularly to the surface, the force it would exert in the outward direction would be 0 (Cos 90 = 0).

So how can the bobbing particles 'push' other particles outward?
