Pre-AP Review 5 Flashcards

9955785732	homologous structures	Structures in different species that are similar because of common ancestry.	0
9955785733	variation	different traits in a species caused by differences in genes	1
9955785734	natural selection	organisms better adapted to their environment tend to survive and produce more offspring. Organisms that are not adapted die. Over generations, the frequency of adaptive traits increases.	2
9955785735	cladeoram	a model slowing evolutionary relationships between species	3
9955793479	ribosome	structure in cell where proteins are synthesized	4
9955801769	vacuole	structure in cell for storage	5
9955814206	specific immune response	reaction to infections by specific pathogens or vaccines. Can trigger immunity to prevent illness in case of future exposure	6
9955835493	insulin	hormone produced by pancreas in response to high blood sugar. Lowers blood sugar	7
9956207657	glucagon	hormone produced by pancreas in response to low blood sugar. raises blood sugar	8
9956232517	cell in hyper tonic solution	will shrink, because water will move out of the cell from an area of high concentration to an area of low concentration	9
9956245287	cell in a hypo tonic solution	will swell or lyse (burst), because water will into the cell from an area of high concentration to an area of low concentration	10
9956257361	cell in an iso tonic solution	will remain unchanged because the concentration of water is equal inside and outside of the cell, so there will be no net movement	11
