Question 1

Can allelochemicals affect the outcomes of competitive interactions?

Answer 1

Yes

Question 2

Some microbes produce some toxins to do what?

Answer 2

To exclude competitors

Question 3

Liquid chromatography?

Answer 3

Separating compounds

Question 4

The toxins in rotten food, do they escape the flesh and goes into, for example, water?

Answer 4

No, they stay in the flesh.

Question 5

Bacteria can compete with small/large animals?

Answer 5

Large animals by actively defending rich food sources

Question 6

Information transfer function of secondary metabolites when in relation to two species interactions can mediate what?

Answer 6

Chemical contracts between organism that can exclude certain types of interactions.

Question 7

Coevolution?

Answer 7

The continual evolutionary change by a species that is necessary to retain “its place” in an interaction because of ongoing (reciprocal) evolution by other species.

Question 8

Phenotype matching?

Answer 8

Outcome is likely to be escalating arms race

Question 9

Gene-for-gene (allele matching)?

Answer 9

Outcome is more likely to be stable cycling (many alleles at the loci in each partner) (dominant strain for a pathogen that falls down, and then you get the next strain coming up, over and over again).

Question 10

Arms race?

Answer 10

If one organism evolves more and more, such as becoming faster and faster, the other organism also evolves more and more, such as the predator also going to go faster and faster

Question 11

Cardiac glycosides destroy what?

Answer 11

Sodium-potassium ATPases and result in heart failure.

Question 12

A singe base pair change in the ATPase makes it insensitive to?

Answer 12

Cardiac glycosides, an example of coevolution.

Question 13

Red Queen hypothesis?

Answer 13

Species (or populations) must continually evolve new adaptations in response to evolutionary changes in other organisms to avoid extinction.
