Question 1

Antibiotic resistance

Each does of antibiotic will allow these bacteria tp survive and pass on their resistant traits to the next generation–more of each generation are resistant until the resistant allele if the most common; at this point, the antibiotic is no longer effective

Question 2

Question 3

Transgenic organism

Answer 3

Question 4

Monoculture

Answer 4

Answer 5

species that are introduced to an area and that out-compete the indigenous species in its trophic level for nutrients and/or prey; are less affected by limiting density-dependent and density-independent factors
