Read the lab procedure for a controlled experiment that looks at the effect of heat on the circumference of bicycle tires.
step 1: pump up six identical bike tires to the recommended air pressure.
step 2: place three tires under heat lamps, and keep the other three tires at room temperature.
step 3: after four hours, measure the circumference of each tire.
step 4: record your results in the table.
step 5:
which step should be next in this procedure?
list the materials that are needed.
write a conclusion for the experiment.
write a hypothesis for the results.
draw a table for the observations.

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good

explanation:

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.
