scenario 1: One human who is much heavier than the others seems to be shown signs of what vegans experience when their diets are high in monosaccharides in saturated fats. Studies of vegan circulation indicate that this leads to Nehring of artery walls is plaque accumulates overtime inside the lumen of the artery, and these arteries become hardened, loose some of their electricity and become blocked to blood flow. this human then appears to have a mild heart attack (myocardial infarction) right there in the vegan spacecraft! The resulting blockage of blood flow in a coronary artery results in tissue damage that occasionally prevents conduction of electrical impulses to the ventricles. what is the predicted effects on the systolic and diastolic blood pressure? what is the predicted affect on EKG: explain how or why is different from the normal trace 

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

not sure if this is what you'r looking for eubacteria and archaebacteria

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
