I have noticed than in people of color, their upper lip is dark most of the time. Why is this? I would think it would have something to do with melanoma, but I don't know.

I'd really appreciate an answer. Thank you very much.

would his (or her) weight change?

Alternate way of asking: If we could isolate the one liter inhaled and the one liter exhaled what would be the diferrence in their weight?

I came across some info the other day that said (if I remember right) that CO2 is denser than Oxygen. So I am thinking that the exhaled liter would weigh a little more than the inhaled liter and hence the body would have lost a miniscule amount.

I am sure this might be more complex with the Krebs cycle and all that but it would seem to me that what I am asking could be tested or perhaps even have an answer right now.......I hope

i know this is true for the animals...but doesnt this hold true for human also..i mean the diseased people are always living in misery, the poor people who cant earn much are always sad..while the rich famous and the goodlooking have the best in life...people with autism dont have achance in this life to compete with the other people..fat people cant live their lives happily..just because they are fat. So only the people who are by socety'd standards considered fit survive happily...

Isnt it sad but true...what are your opinions on this?

I know happiness is all in the mind...but this thought just struck my mind....?

I'm a freshman in college - need help answering another one of these "challenge questions"

The classic experiment by Pasteur tested the hypothesis that cells arise from other cells. In this experiment cell growth was measured following sterilization of broth in a swan-neck flask or in a flash with a broken neck:

a. Which variables were kept the same in these two experiments?

b. How does the shape of the flask affect the experiment?

c. Predict the outcome of each experiment based on the two hypotheses.

D. Some bacteria (germs) are capable of producing heat-resistant spores that protect the cell and allow it to continue to grow after the environment cools. How would the outcome of this experiment have been affected if spore-forming bacteria were present in the broth?

Appreciate the help - thanks!

I'm a freshman in college - need a little help answering this "challenge question" in my biology book.

Exobiology is the study of life on other planets. In recent years, scientists have sent various spacecraft out into the galaxy in search for extraterrestrial life. Assuming that all life shares common properties, what should exobiologists be looking for as they explore other worlds?

Appreciate the help - thanks!
