This plant typically lives in an acidic, boggy, nutrient-poor habitat. They are known for opening/closing their ion gated channels in order to create sudden action potentials. They use water potential to help them alternate between turgid and flaccid. They also contain large amounts of proteases and chitinases.

Things that pGlo: Explain what happens in terms of bonds and energy when a glow stick glows. AND how do scientist determine whether or not transformation experiments are successful?
Bonds form = energy released.
They insert a resistant gene, pGlo gene, and/or radioactive marker into the plasmid (in addition to the gene of choice.)

Discuss GMO's
One of the first GMO's was the FLVR SAVR fruit/vegetable that after many centuries of breeding and insertion of genes (1980's) we created the first "Family Fare" edible red vegetable.

When sampling a population of ant lions it was discovered that from 100 individuals, 38 had long pincers and 52 had short. Is there statistical evidence that long pincers might be an advantage or is the difference due to chance?
Long pincers is dominant to short. What is the dominant allele frequency?

Explain the use of the "balance" word that is used in thermodynamics as well as Hardy-Weinberg.

Explain kinetic molecular theory.
AND name examples of things that cause a confirmational change and therefore speed up chemical reactions BUT do not change energy absorbed or released.
