plants sneezing, is it caused? or just a mystery that will continue to puzzle scientists and researchers, for a century, and if plants do sneeze, why don't they enter hot dog eating contests with Adam Sandler, or clone #18893627 from star wars, do they, do they not? or is this just an unsolved mystery in this crazy, crazy mixed up world, but one things for sure, old, fat, movie actors can pilot small aircrafts with the help of a monkey, jacked up on Vault, and grapes.

Why isn't respiration proportional to temperature of the surroundings?

Basically of got this graph that shows that as temperature increases, so does respiration, up to a point.

The data is

Temperature / Distance moved on respirometer

20c / 10mm
25c / 14mm
30c / 16mm
35c / 20mm
40c / 16mm

The questions asks whether or not the distance increases proprtionally to the temperature (no) but i also asks why not which is the bit i don't understand.

Basically why isn't respiration proportional to temperature?

As an undergraduate I majored in Anthropolgy (mostly biological anthropology and human evolutionary ecology) and also alot of evolutionary psychology classes. I also know calculus and am very strong in statistics. I only took 8 hours each of chemistry and biology though. I was always interested in evolution's implications on humans, but am now thinking that I would rather go to Grad school to study genetics and evolution itself.

Could I be admitted directly to a biology program with this background our am I doomed to studying humans unless I make up these undergrad defeciencies?
