a. the inner planets revolve and rotate slower than the outer planets.
b. the inner planets revolve and rotate faster than the outer planets.
c. the inner planets revolve slower and rotate faster than the outer planets.
d. the inner planets revolve faster and rotate slower than the outer planets.

The correct answer to the question is : D)The inner planets revolve faster and rotate slower than the outer planets.

EXPLANATION:

Before going to answer this question, first we have to know about outer and inner planets.

Outer planets are the planets which are present after the asteroid belt and are generally made up of gaseous substances. The outer planets are the Jupiter, Neptune, Saturn, Uranus respectively.

They are present at large distance from the sun. Hence, their period of revolution around sun is more as compared to inner planets.

The inner planets are present before the asteroid belt. They are Mercury,Venus, Mars and the earth.

These planets are present at smaller distances as compared to outer planets. Hence, their period of revolution around sun is less.

The rotational speed of outer planets and inner planets also vary. The outer planets rotates faster as compared to inner planets.

Hence, the correct answer of this question is the fourth option.

answer: the correct answer for the fill in the blank is rods.

rods are the specialized photoreceptor cells that are present in the retina of human eye. they are responsible for vision in the night time ( also called scotopic vision). they have very low visual acuity and color distinguishing ability.

as they are responsible for vision in night time, therefore they are found predominantly in the nocturnal animals.
