A marine biologist is examining the effects of oil pollution on a population of birds known as seagulls (Larus canus). She is particularly concerned that oil pollution may reduce the number of eggs raised in a seagull nest. During one breeding season, she counted the number of eggs present in a sampling of six seagull nests near each of the 14 refineries throughout the state. She discovered that seagulls laid and raised an average of four eggs per season. To confirm her hypothesis, the researcher must now examine seagull nests that have not been exposed to oil pollution. The researcher believes she is correct, and so expects to find D) 4-6 eggs per nest.

Smooth muscle is the type of muscle tissue responsible for propelling food along the digestive tract.
Smooth muscle is a type of muscle tissue that can be found in the walls of hollow organs of the body such as the digestive system, urinary tracts, tubes such as blood vessels and reproductive system. Smooth muscles contracts involuntarily and allows the walls of organs to move. The layer of smooth muscle present in the digestive system helps to break down food and propel it along the tract. Food substances and liquid moves from one organ to the next through the muscle action.
