BIOL 1104 EXAM 1 QUESTIONS AND ANSWERS-the rate of production of new biomass by an individual,
population, or community
-the fertility or capacity of a given habitat-everything is
dependent on this Correct Answer productivity
(couldn't upload image) This histogram shows two overlapping
distributions of the effective number of alleles for two types of
paw paw populations. The distribution for wild populations is
shown in teal. The distribution for anthropogenic populations is
shown in red. What can you conclude from these data Correct
Answer anthropogenic populations tend to have lower effective
number of allele than wild populations
2 conditions of evolution Correct Answer 1. heritable variation
2. differential survival/reproduction (includes both random and
non random processes)
a hypothesis Correct Answer a population is often a
a mature maple tree can have a mass of many tons (dry biomass,
