sammy is performing an experiment to determine how fast the sun
can heat a container of water on a warm summer day. he filled a 1l
beaker with distilled water and placed it in direct sunlight (the outside
temperature is 27 °c. the organized his data in this data table.
if sammy were to leave the container in the direct sunlight for an
additional hour, what would he expect the temperature to be?

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.

the tricuspid valve is present between right atrium and right ventricle

i'm thinking 600 feet deep in one of the finger lakes.

the species living around the vents are especially good at dispersal.  

deep-sea vent originates on the floor of the ocean when seawater circulates through hot volcanic rocks, usually situated where the new oceanic crust is being produced.  

biological dispersal refers to the movement of species from their location of birth to their site of breeding, or from breeding site to another. similarly, the oceanic dispersal refers to the movement of the species from one land mass to another by sea crossing.
