the division of a single nucleus into two genetically identical daughter nuclei
-type of cell division that produces genetically identical daughter cells
the chemical in it breaks up large globs of fat, allowing it to be washed away by water. Because membranes of cells are made up of phospholipids. Exposed to high concentration of this chemical releases the contents of the cell into solution.
forms a layer on top of solution, DNA will precipitate at the boundary between the solution and alcohol.
1. Know the stage of mitosis in which DNA replication occurs.
The natural variation among individuals within a population of organisms results in differences among them in their ability to survive in a given environment, traits that increase the chance of survival or reproduction are called adaptations, those with adaptations are considered to have more fitness than others meaning they have more surviving offspring.
the contribution an individual makes to the gene pool of the next generation relative to the contribution of other individuals in the population…higher fitness means more surviving offspring
First Eukaryotic Cell
Sixth major extinction
when a population goes through a rapid and dramatic decrease in size, also called population crash.
