Phil is conducting a seed germination experiment. He places 3 groups of lettuce seeds in a
34º Celsius incubator with adequate moisture. One set of seeds is placed in a dark area with
no light source. A second set is placed under artificial light and third set of seeds is placed in
direct sunlight. This experiment is intended to test Phil’s hypothesis that light is necessary for
lettuce seed germination.

63. Osmometer cells in the brain sense an increase in the salt concentration of plasma. This
information is sent to the hypothalamus, which notifies the pituitary gland to release the
hormone, ADH. ADH causes the kidney to save water, which lowers the salt concentration of
the plasma. What characteristic of life does this overall pathway represent?

Turtle hatchling survivorship rate is low in many turtle species due to predation. Amanda
researched the predatory rate on a species of turtle eggs in the Red River. The eggs were
harvested from trapped turtles and the egg’s cloaca film (reproductive discharge) was either
washed off or left on once gathered. Research suggests that predators use the female’s cloaca
scent to locate the eggs.
The eggs were only handled when wearing gloves and then reburied along islands where the
turtles were trapped. The nests were monitored by cameras and manually on foot and data on
nest predation were recorded.
