The prokaryotic cell cycle has five distinct stages. what would be the correct order of these five stages (from beginning to end) using the five statements below? a. as the cell increases in size, new plasma membrane is added, pushing chromosomes apart. b. the parent cell divides into two daughter cells, with each one genetically identical to the parent cell and containing a single, circular chromosome. c. the single prokaryotic chromosome is usually attached to the plasma membrane of the cell. d. the chromosome replicates, producing two identical copies that attach to plasma membrane at nearby, but separate, sites. e. the plasma membrane grows inward between the two chromosome copies.

When organisms are classified ,they are given a two part name

To answer this question, researchers studied populations of the dusky salamander (desmognathus ochrophaeus) living on different mountain ranges in the southern appalachian mountains. the researchers tested the reproductive isolation of pairs of salamander populations by leaving one male and one female together and later checking the females for the presence of sperm. four mating combinations were tested for each pair of populations (a and b)—two within the same population (female a with male a and female b with male b) and two between populations (female a with male b and female b with male a). the proportion of successful matings for each mating combination was measured. for example, when all the matings of a particular combination were successful, the researchers gave it a value of 1; when none of the matings were successful, they gave it a value of 0. then the researchers calculated an index of reproductive isolation that ranged from 0 (no isolation) to 2 (full isolation). the reproductive isolation value for two populations is the sum of the proportion of successful matings of each type within populations (aa + bb) minus the sum of the proportion of successful matings of each type between populations (ab + ba). the table provides data for the geographic distances and reproductive isolation values for 27 pairs of dusky salamander populations.

Food contains a sugar called ( ), which is broken down in a process called cellular ( ). this process uses ( ) to break down food molecules and provide energy for cells. fill in the parentheses
