Your answer is
One of the most effective methods that can be used by researchers to avoid sampling bias is simple random sampling, in which samples are chosen strictly by chance. This provides equal odds for every member of the population to be chosen as a participant in the study at hand.
Answer:
Cross-pollination.............
Divergent boundary.
This is the boundary between two tectonic plates move away from each other in opposite directions.
Explanation:
One major example of a divergent boundary is the mid-Atlantic ridge that cuts, longitudinally, across the middle of the Atlantic ocean.
When two tectonic plates move away from each other in opposite directions, the void they leave in between is filled by rising magma from the mantle and cooling to create new crust. A mountainous ridge along a boundary is evidence of a divergent boundary. The Atlantic ocean will therefore continue to widen as the North American and Eurasian Plates move away from each other. As new crust is formed at divergent boundary, old crust is being consumed at convergent boundary on another end of earth. This way tectonic plates of earth renew themselves.

Answer:
Trichromatic vision.
Explanation:
Trichromatic theory may be defined as the theory that posses of three independent channels that are used to convey the color information. They are derived from the three different cone cells.
The television also produce three primary colors by the use of trichromatic theory. The receptor or these colors in human are greater than three as different colors have different intensity of light. The opsin protein plays an important role in the trichromatic vision.
Thus, the answer is trichromatic vision.
Answer:
The Mid-Atlantic Ridge runs down the center of the Atlantic Ocean. ... The rift valley is 1 to 3 km deep, about the depth and width of the Grand Canyon. In contrast, the East Pacific Rise spreads fast at rates of 6 to 16 cm per year (more than 20 cm per year in the past).
