Answer:
D. The scientist uses tennis balls to show the position of the planets and Sun.
Explanation:
In a layman's terms, the solar system is a system consisting of the sun and the planets that orbits around it. These planets are as follows; Mercury, Mars, Earth, Saturn, Venus, Jupiter, Neptune, Uranus etc.
According to this question, using a physical model to represent or describe the solar system means the use of physical objects that can easily be seen or identified. Based on this explanation, the use of tennis balls to show the position of the planets and Sun suits the physical model description of our solar system.
Answer:
Option A
Explanation:
The vestibular system is a part of the inner ear that provides the most important contribution to the sense of balance and coordinating movement with balance. This system is made up of two parts which are the three semicircular canals and the two otolith organs. The two otolith organs are the saccule and the utricle. The utricle is sensitive to changes with regards to horizontal movement and the saccule provides information about vertical acceleration. They are able to do this due to their orientation in the inner ear providing spatial orientation with regards to movement and balance. the three semi circular canals includes the horizontl, poterior and the superior semicircular canals. they provide sensory inputs.
The smallest fragments travel the fastest because a smaller molecule has less resistance making it easier to travel through the gel.
