If there is no variation in a population, or if the only variation is acquired and not inherited, or if all of progeny survive to equally reproduce, will evolution occur? What's your opinion?

I have been sick for about two weeks with a feaver, headache, sour throat, and more and haven't been able to finish my science homework. If anyone could help me out, that would be great.
I need to know under which color light would the rate of photosynthesis be highest and which would be lowest out of the colors red, blue, and green. I'm really sorry that I have bothered everyone with this question but it would mean a lot to me if someone would please help me out.

It show the planets shrunken down ten times and the atom magnified ten times. Everything lines up the same! My husband saw it on Discovery or something and has been trying to find a copy for years. Maybe that isn't the exact title, but you may have an idea of what I'm looking for. Thanks

Science is becoming unreliable because it is being used by opposing political forces (consrvatives and liberals) for their own tactical purposes. For example, when Repulicans are in power, they try to manipulate statistics to show that the economy is doing well. They also try to deny the fact that global warming exists. History is also manipulated. Irrespective of real facts, Republicans praise all the conservative presidents and historical figures and Democrats do the opposite. How to preserve the objectivity of science? Is it at all possible?

..the average family compact car doing average annual mileage OR the average family (2 adults + 2 children) just breathing for a year? (We can leave digestive gases out of the equations!) I have seen a calculation showing that they produce about the same...2.5 tonnes. Is this right? (..and pretty scary when you look at the impact of global population growth, irrespective of what we do to reduce industrial emissions!) Thanks for you replies.

Just a day ago (11/4), we should have moved our clocks back one hour. When we go into spring/summer, we move it back up one hour.

Which is longer, the number of days with one hour back or the number of days with one hour ahead?

Since this is a highly scientific poll, you can only answer one of the following.
Have you ever seen or experienced any of the following:

1. Chupacabras
2a. Alien Encounter - (nice aliens, example - didn't harm you, took you for a ride in his spaceship)
2b. Alien Encounter - (mean aliens, example - amputated a limb, performed bodily cavity probes).
3. Big Foot
4. Other weird things.

Thanks for your time, and for helping me with my research.

What is the difference between infrared given off by hot stuff and infrared of remote controls. Why is it that infrared remote controls appear to "light up" when seen through a digital camera but other hot stuff appears the same?
How come infrared remote controls dont emit heat then?
