Answer:
It has long been known that static pressure affects middle-ear function and conventional tympanometry uses variations in static pressure for clinical assessment of the middle ear. Middle-ear under-pressures tend to reduce the velocity magnitude more than do middle-ear over pressures.
The effect of middle-ear static pressure on the acoustic response of both structures is similar in that non-zero middle-ear static pressures generally reduce the velocity magnitude of the two membrane components in response to sound stimuli.
Answer:
Natural selection is a theory originally popularized by Charles Darwin. According to this theory, animals in the natural environment change over time as beneficial traits are preserved, and traits which do not advance the species are slowly weeded out. Natural selection, a concept first theorized by Charles Darwin, is the adjustment of genes throughout generations based on factors that help it survive. Sometimes this is survival of the fittest or the organisms that are better suited to the environment in other ways.

This is because both strands of DNA have complementary bases. The nucleotide sequence of each automatically gives the needed information to produce its partner. This needed information is Genetic/DNA/Parent Cell. Each cell serves as it's own template in order to acquire this.
The experimental group is the group you change from the normal. the fertilizer group is experimental
She could use a control to compare her data to and make sure it is cleaner. Ex. Use the old detergent on ten shirts and then use the new detergent on another ten shirts. She would then compare the shirts she did each detergent on and come up with her conclusion.
