in relation to photosynthesis. I know that it is another word for something, probably ATP, NADPH or something, so an one word answer is good. ^^ Thanks in advance!

I need help on these 3 Hardy Weinberg Problem..can someone go through the steps of each one to show how you got the answer? I'm totally confused!

4. A population of mice shows a recessive trait of white fur 49% of the time. What is the frequency of the dominant allele?

5. In a midwest town with a population of 9375, 75% of the townsfolk show the dominant trait of free earlobes. How many people in this should be heterozygous for free earlobes?

7. the frequency of stillbirths homozygous for a recessive lethal gene is about 1 in 25000. What is the proportion of the carriers (heterozygous) in that population?

Assuming that the human species originated in Africa, why do you think early humans left Africa and began to populate other parts of the world?

Were they chasing after herds of animals who were migrating out of Africa?

Or was it because of unfavorable climactic conditions?

Or Was it because of tribal feuds? Were people banished?

What is you theory on this?

I know an atigen is A substance that when introduced into the body stimulates the production of an antibody. Antigens include toxins, bacteria, foreign blood cells, and the cells of transplanted organs, but I can't quite gather what this means.

No, this is not for homework, I was just wondering..


Thanks.

By the way this is a science lab.

I'm learning how to karyotype, so I had to match up the chromosomes to their mates. But when I cut them out I noticed I had an extra chromosome. When I was done all of the chromosomes were matched up with their mate except for that one chromose. I checked to see if maybe it was 3 of the same chromosome, but there wasn't. So what is it? Is it a leftover sex cell? If it wasn't for that leftover my person would be a female, but does that extra chromosome mean the person is a hermaphrodite? What sex is it?

I think our intense brain activity is interfering with it. We walk through the world taking shallow, oxygen-low breaths. Why?
