What is a gene pool? The complete genetic code of an individual The possible combinations of alleles between two parents The range of phenotypes within a population The different alleles available for an individual gene The total of all alleles for all genes in population Trees, kelp, and cyanobacteria can all store solar energy as food; some archaeans can store chemical energy as food. These organisms could all be described as Primary consumers Phototrophs Photosynthetic Autotrophs Heterotrophs Sea otters prevent the transition from a kelp forest to an urchin barren by keeping the urchin population in check. The presence or absence of sea otters has an impact on the community beyond what is expected given their relative abundance in the community. Otters in this scenario are Decomposers Trophic cascade leaders Dominant heterotrophs Keystone species Resource partitioners A typical example of a population limiting factor that is densityindependent is Disease Predation Competition Flooding Famine

Cystic fibrosis is a recessive trait. If two parents are Cystic fibrosis carriers and their first child has the disease, what is the probability that their second child will have Cystic fibrosis? 0% 25% 50% 75% 100% Some traits are coded for by genes that are located on the x chromosome. These traits are known as Homologous Autosomal Non-autosomal Sex-linked Gametogenic
