C) As hydrilla is aquatic in nature, the roots do not have to search for water, and there is no need for xylem to absorb water because the plant is surrounded by water.
In scientific notation, the value of the speed of light in a vacuum
will be written as 2.995 * 10^8. When this value is represented in the form of
a * 10^b, then, a = 2.995 and b = 8.
The value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. In this case, the scientific notation will be written as 3 *10^8.
