Answer:
I) George is correct
Reason: Sound waves, an example of mechanical wave is only longitudinal NOT tranverse
Explanation:
The difference is that the direction of a tranverse wave is perpendicular to the direction of vibration unlike the direction of a longitudinal wave that is same as the direction of the vibration.
Also examples of mechanical waves are water waves (tranverse) and sound waves (longitudinal). Thus GEORGE IS CORRECT having stated that "sound waves were longitudinal and not transverse" unlike sally who made a non-specific statement
The answer is C- warm air rises and takes the heat with it, eventually it cools and sinks
Letter A, a hypertonic solution.
Answer:
The fox population on the Islands experiences genetic drift whereas foxes in the forests has Hardy-Weinberg equilibrium.
Explanation:
The fox population on the Islands experiences genetic drift because there is no chance of introduction of different type of foxes in these Islands which experiences less variation in the population of already existing foxes. Genetic drift is the change that occur in the frequency of an existing gene allele in a population due to random sampling of organisms. Genetic drift may cause gene variants to disappear completely with the passage of time which leads to reduce genetic variation. The foxes that is located in the mainland forest experiences Hardy-Weinberg equilibrium.
