for me, i think it is very dangerous, to mix human dna with animal dna, and could open up a door to new diseases.

I've seen people say this as if it's some scientific fact. Is it really 80% and has it been scientifically proven? I can't find anything on Google about it except random people who say the same thing, so I'm not sure if this is exactly true.

This isn't a question, so I'm not too worried about answers. However, I've seen a lot of arguements about evolution on here, and I thought people may be interested in reading the following article:

If this trend continues, America will find itself controlled by extreme religious conservatives. This will lead to America's downfall. It will be like when all science was herasy!! I just hope that Americans who aren't blinded by religious pseudo-science will act to make sure science stays as science, and religious beliefs stay in the philosophy classroom, and not be taught as 'scientific fact'.

Everyone is entitled to their beliefs, but please let's keep the distinction between science and religion clear.

During Cheese production, rennet is used to solidify the protein in the milk. Rennet is a commericially prepared form of rennin, an enzyme found naturally in the stomachs of young mammals.

Explain why the temperature of the mil needs to be kept between 30 and 4 degrees C during this stage of cheese production.

As I understand it, unoxygenated blood has that metallic taste to it because of the iron based hemoglobin. I was wondering... after the blood is oxygenated, does the metallic taste go away? Or do any other changes occur? Might sound like a weird question, but I'm seriously curious and want to know.

Hardy-Weinberg Equilibrium Model
Problems (Answer is supplied; you show the work.)

Remember that the letters refer to frequency of:
p = dominant allelesp2 = homozygous dominant trait
q = recessive alleles2pq = heterozygous trait
q2 = recessive trait


1. In a population of 500, how many homozygous dominant individuals are present if the recessive allele shows up at a frequency of 60%? Answer: 80




2. Suppose you have a population of guinea pigs in which 2/3 of the alleles for coat color specify black (dominant) and 1/3 specify white (recessive). What is the frequency of dominant and recessive traits, according to Hardy-Weinberg, in this population?
Answer: 44% and 11%, respectively




3. Of 400 people who dwell on a Pacific island, 16 are recessive for a trait that has only two different types of alleles in the population. What is the number of heterozygous people in the population? Answer: 128





4. In a population that is in Hardy-Weinberg equilibrium, the frequency of the recessive genotype is 49%. What is the percentage of the population that is heterozygous?
Answer: 42%




5. If the frequency of the dominant allele in a population is 36%, what is the frequency of the recessive trait in that same population? Answer: 41%

For example, in a pitch black cave, would a nocturnal animal be able to see anything?

Excludes bats, of course.
