Recall that the biological species concept defines a species as a group of populations whose members have the potential to interbreed in nature and produce viable, fertile offspring. this means that all members of these populations (called conspecifics) can contribute to a common gene pool. conspecifics are organisms or populations that belong to the same species. genes are transferred between conspecific populations through both direct and indirect gene flow. biologists studying disease susceptibility in mice used genetic techniques to look for gene flow in 12 wild populations of mice. the populations (designated a through l) were located along a 210-km transect line. the researchers found evidence of gene flow between some, but not all, pairs of populations. in the grid below, a "+" indicates a pair of populations in which direct gene flow was detected, and a "–" indicates a pair that showed no evidence of direct gene flow. for reading this grid, see hint 2.

Determine if the following statement is true or false. if true, choose true. if false, choose the rewording that is true. according to the law of independent assortment, alleles for each gene are inherited together so that they always stay together. according to the law of independent assortment, offspring express a combination of their parents' traits. according to the law of independent assortment, alleles for a characteristic split during meiosis and combine during fertilization. true according to the law of independent assortment, alleles for each gene are inherited independently so that no two alleles stay together.

Students in biology are studying the macromolecules of life. they used a calorimeter to determine the calories in various types of food. once the lab was completed, the students ate the left over food samples. monica commented that in just 6 or 7 "chews" of the saltine, it was gone; nothing but a sticky paste in her mouth. elaborate on what happened chemically while chewing the saltine. include the macromolecules present.

The is an estimate of the fewest number of organisms a population needs to avoid extinction. this measurement will most if the number of offspring each female in the population produces increases. if the population's this measurement will most likely increase. 1 population density, minimum viable population, carrying capacity 2 decrease, be unaffected, increase 3 death rate increase, dead rate decrease
