True altruism in animals has been overwhelmingly discredited, the majority of perceived cases being attributed to either kin selection or recipricl altruism. Can seemingly altruistic behavior in humans be described as such also? Western society has entire career fields based on altruism, e.g. life guards, police officers, fire fighters, military. How is this paradox reconciled?

Well marriage is actually a formal union of 2 people typically recognized by law. But what is the future of human relationship?
In our times, People are getting married because they want to feel financially secure. Divorces increase, marriages last only for months or for a few years. Ofcourse there are some exeptions of loving and balanced long relationships but as years go by, there are becoming extinct.

I have a comic strip comic and the calories one is about a family arguing over how many calories are in lite things and regular slices of bread.
Also, the other one is a Ripleys Believe it or Not.. a caterpillar has over 4000 muscles while humans have less than 800.
Are these things real science?

I mean, IF evolution did occur, I dont think it would have happened the way scientist claim it has. Without eyes or eyesite, how did DNA know how to create it? How did an organism know it needed eyes when it never had it before? Without eyes, and with evolution, wouldnt it find a way around the need for eyesite? The cause for evolution is the need for something better, so the first single cells wouldnt have evolved because they were/are perfectly fine where they are. Survival of the fittest, if we came from single cells, why do we still have them today?

Suppose a plant is given water labeled with the radioactive isotope 18O and normal, unlabeled CO2. What products would you expect to see containing this isotope after the plant had been allowed to photosynthesize for a while? What if the plant had been given CO2 labeled with 18O and normal water. Explain your answers.
