Principles of Competitive Exclusion: When 2 species compete for the same limiting
resources, one will go extinct unless one of these three things happen:
Give this one a try later!
1) Environmental heterogeneity: enables competitive displacement
2) Metapopulations structures: prevent a species from going extinct
everywhere at the same time
3) Disturbance (abiotic and biotic) prevents the better adapted species
from completely excluding the other
Bacteria Plasmid
Give this one a try later!
, Small, double stranded piece of DNA that exists and replicated
independently of the bacterial chromosome; usually circular
Binary Fission
Give this one a try later!
Reproductive strategy of most haploid bacteria/archaeal cells to create
identical cells
1) cell elongates
2) replicates their chromosome
3)divides down middle with one chromosome in each new half
Which of the following members of the class Arachnida are primarily parasitic:
a) spiders
b) scorpions
c) ticks and mites
d) trilobites
Give this one a try later!
c) ticks and mites
Derived character states that related taxa share/ shared ancestral traits
Give this one a try later!

Why is the amniotic egg considered an important evolutionary breakthrough?
Give this one a try later!
It allows deposition of eggs in a terrestrial environment
Costal upwelling is when ______ from dead organisms accumulate in deep water and
then resurface to produce highly productive areas
Give this one a try later!

Smooth ER in Eukaryotes
Give this one a try later!
Lacks ribosomes on its surface
Most of the world's major deserts occur in two latitudinal bands that are centered at
30 degrees N and 30 degrees S latitude. This pattern is best explained by:
Give this one a try later!
, Major patterns of atmospheric circulation above and below the equator
due to equatorial heating and circulation cells
Which of the following is NOT a characteristic of echinoderms?
a) water vascular system
b) pentaradial symmetry
c) bilaterally symmetrical larvae
d) cephalization in the adult
Give this one a try later!
d) cephalization in the adult
The lysogenic cycle occurs when the virus enters into the host genome; in the _______
cycle occurs when the virus kills the host cell
Give this one a try later!
Lytic
_____-selected species have high reproductive rate, small body size, occupancy of
unstable environments, and minimal parental care; _____-selected species have large
body size, long life expectancy and the production of fewer offspring
Give this one a try later!
