The goldenrod gall fly lays its eggs on the goldenrod plant.  The larval fly causes the plant to form a structure called a gall in which the larva lives until it becomes an adult fly.  The flies cannot reproduce without goldenrod. The distribution of the goldenrod gall fly is primarily determined by Group of answer choices -random chance -biotic factors -abiotic factors

Why would you not want to harvest to a point where salmon populations are kept at very low numbers? Select true or false for each answer. small populations [ Choose ] are more likely to go extinct do to unforeseen (stochastic) events small populations [ Choose ] are more likely to lose genetic diversity small populations Choose ] are more susceptible to inbreeding depression small populations [ Choose ] are not growing very quickly so you would have low fishing yields

Species 1 2 3 5. A biologist notices that plants growing in dense thickets of vegetation (uncleared areas) tend to be much smaller than when they are grown in isolation in cleared areas in his garden. As they are a very cool gardener, in addition to being a very cool person in general, they do an experiment and observe the following for five plant species: 4 5 Biomass of the species in uncleared areas (g) 19 14 14 29 50 Biomass of the species in cleared areas (g) 20 34 48 39 51 Explain these results and the concept behind them thoroughly, including in quantitative terms

Game theory applied to evolution claims that an ESS (Evolutionarily Stable Strategy) can exist in a population. This ESS is a strategy that if all individuals adopt it, no mutant strategy can invade the population. Is the “jumping off a cliff when the food supply is limited” a real ESS? Why or why not?
