I was learning about mitosis and meiosis in school and had a question. I know in Mitosis you first start off with a Diploid (2N) cell and then end up with two daughter cells that are also Diploid.
I was a fool and dissolved my antibiotic (Kanamycin) into Tris Buffer rather than H?O. The Kanamycin still seems to be active but a fellow labmate mentioned that Tris messes around with the membrane
While speaking with my co-workers, the topic of tumors growing things came up. The examples were (and backed by images) of tumors growing a tooth, hair, and sometimes even more complex objects such
As the old joke goes, "God must have been a civil engineer. Question: Who else would put a waste facility straight through a recreational area?"
Most people I asked answered: "There's a difference because it's transformed into energy, like heat...". I think that's bull-excrements. There's still the law of conservation of mass: our body does
I'm not sure if this is actually a philosophical question, but I was reading a timeline of life on earth and I came to this:4500-3500 Ma The earliest life appears, possibly at Alkaline vents with the
Now normally when a cell does not receive sufficient oxygen to undergo its natural processes, it usually breaks down glucose anaerobically to generate ATP and lactic acid. However, in the case wher

Antibodies or immunoglobulins are proteins made by the immune system in response to alien(!) molecules. Each antibody binds to its specific antigen.
I assume other species don't have these. Sure there are instances in the natural world where you can see individuals of the species gather around the dead one. Sometime even the alpha male in the gr
