Carp heart rates vary with ambient water temperature; slower for lower temperatures. Also some carp exhibit lowered heart rate in hypoxyic conditions. Here's a paper that looked the effect of hypoxyic conditions on a carp heart that gave heart rate as 50-90 bpm. As well as producing some graphs that...

wbla3335 has essentially got it right. Variation in indiviuals leads to some individuals surviving and reproducing better than others. Those that survive pass on those traits to their offspring. Over time the traits that allow for better survival or reproduction will occur with greater frequency in ...

I know that the eurasian water shrew has venomous saliva. Maybe that video was in Life of Mammals with David Attenburough?

Yeah, I was thinking the question is worded wrong. I searched for trypsin and found a lot of studies looking at it in newborns. In addition, it seems that trypsin works best in a slightly alkaline environment.

Wouldn't the [b]lowest[b] temperature to kill all yeast be absolute zero? Hahahahaha. Seriously, I would probably plot this as an x-y graph.

You're right blcr11.....genotype generally refer to the entire genetic makeup of the indiviual. But I understand what you mean by genotype of a gamete. :) Yields the same answer in any case.

No problem Dr. Stein. I like squid to eat too. In fact, the squid I will be studying are caught by fishermen and mostly sent to Asia. Maybe to you?

Marine intertabrates

Anybody out there into marine intertabrates, especially cephalopods? I just got my first permanent job as a biologist with the California Department of Fish and Game, working with fisheries dependent data on market squid. I think it will be fun. I took me a long time to finish university and I had t...
