This is coming from a fellow student in a BIO class who is originally from India. Once again it did seem odd to me.

Yeah I thought it was pretty weird that this student mentioned this and even my professor had a confused look on her face. I don't see why domesticated ducks could not fly, other than having their wings clipped. The only explanation I could think of is that where this student is from maybe the ducks...

Flightless Birds

In my lecture today we were talking about birds.
A student mentioned that he was from India and over there no ducks (domesticated and wild) actually fly. He thought that they were flightless birds until he came to the U.S. Can anyone explain why this may occur in India? Thanks

"Glacial acetic acid is called "glacial" because its freezing point (16.7 C) is only slightly below room temperature. In the (generally unheated) laboratories in which the pure material was first prepared, the acid was often found to have frozen into ice-like crystals. The term "...

UV Light

I know that over exposure to UV light increases the chances of getting skin cancer. I'm curious to know whether it increases your chance of getting other cancers as well?

If you have a Biology book you should be able to figure those questions out yourself.

The phospholipid bilayer is both hydrophobic and hydrophilic. Polar molecules have a hard time entering the cell is because it is hydrophilic and can't interact with the hydrphobic tails inside the membrane. In order to go through it uses facilitated diffusion.

The problem with HIV is that the virus itself keeps adapting to the new environments inside the body. As soon as a new vaccine is used for a patient, the virus begins to adapt until it reaches a point where the vaccine is practically useless. That's why we have to keep finding new vaccines. Some doc...

I don't know about lily reproduction specifically but I do have lilies in my room as we speak. Ever since you asked your question I have been looking for some form of a seed in them. One thing I recently noticed is that one of the flowers is dripping a clear thick liquid at the tip of the carpel. I'...
