It's a common recommendation these days that people should eat a lot of fiber for colon health, heart health etc. But as we know, foods that are high in fiber often cause flatulence. Beano contains an enzyme that breaks down certain sugars in foods that cause gas. But is Beano breaking down the chemicals that are supposedly good for colon and heart health? In this sense, could be Beano be undermining the health value of high-fiber foods?

Science has allowed us to clone animals with DNA. If we were to find Jesus's DNA, say where he was crucified at, would we be able to clone Him since we would have his DNA? What would His DNA look like even if we found it? Couldn't we determine then if God was man or if God was God? Or would we not even think it was DNA because God is God and we couldn't even know if God has DNA?

This is a lab that we did in class, but the explanation makes no sense, we need to know the concepts for the test. In beaker 1, is plain distilled water. A slice of cucumber is put in it. In beaker 2, a slice of cucumber the same size is placed in a water and salt mixture. Let it sit for 45 mins. And wa-laaa! The slice of cucumber placed in distilled water is firm, and hard. The slice placed in the salt mixture is flimsy, and essentially--dead. It shrunk, and it wobbles. Why does the cucumber react so differently? What's the scientific explanation?

I have to write a paper on ecology in terms of population growth and human activites on the environment. I have to be sure to mention the examination of the dynamics of population growth on the environment, explanation of the concept of regulation of population growth through community interactions and the evaluation of the effects of human activites on ecosystems and the biosphere. I do not care for science at all. I have done research but am still confused and do not know where to even begin my paper or what to include in it. It needs to be 700-1,050 words and sound scientific. Any pointers, information, topics, explanations, etc. Help me please.

All birds lay eggs. There are no avian species with a reproductive system similar to placental mammals, and there are no ovoviviparous species that retain the eggs internally until they hatch. Briefly describe how this phenomenon would be approached from a proximate vs. an evolutionary viewpoint. Help me with this! Proximate vs. evolutionary viewpoint???

Designer babies are defined as works of biotechnical engineering and customizing genes of an embryo in order to create a "perfect" baby. Right now it's an illegal practice, but they say that designer babies are bound to become a legal reality in about two decades...

What are your views? Are you for or against the creation of "perfect" babies by tweaking a few genes? Explain why if you can :)

thanks!

Sometimes science is straightforward - you can just measure data to support your case eg toss a coin and count it and you can show head/tails is roughly 50/50.

Sometimes it is about having a theory that explains the data and slowly building on this case so that the scientific community accepts it as the most likely explanation. If your case it strong enough it almost becomes accepted as 'fact'.

An example is evolution - the fossil record, mutations in genes and observation of microbial evolution all support it as the most likely explanation.

However Creationists would say that God fits the same purpose, a single unifying theory that explains all the observations.

Philosophically how can you differentiate between these two?

A friend told me that he saw a Discovery Channel program which gave the information that Chinese people physically cannot develop large muscles. I don't know the science behind it but maybe it would explain why many Chinese people are small (in muscle mass) compared to other races. I was just wondering if this is complete nonsense or if there is any truth behind it.
