Answer:
x = 2000 Km
Explanation:
Given
y = 10 km
Slope: 1 : 200
x = ?
We can apply the formula
y / x = 1 / 200 ⇒ x = 200*y = 200*10 Km
⇒ x = 2000 Km
Answer:
The answer is D.
Explanation:
They vibrate parallel to the wave.
During the propagation of a sound wave in air, the vibrations of the particles are most accurately represented as longitudinal. Longitudinal waves are waves in which the motion of the individual particles of the medium occurs in a direction that is parallel to the direction of energy transmission.

A
Explanation:
It would not be C because prokaryotic cells don't have a nucleus. And if you're looking for a body in the cell that controls the nutrients and water it would be A.
Organisms that existed over a limited period
Explanation:
Index fossils are organisms that existed within a limited period in the geologic record.
These fossils are indicator fossils that serves as guide to define the relative ages of rocks in a sequence.
Here are some characteristics of index fossils:
- they must have existed over a limited period in their history.
- they must be very distinctive with short evolutionary tend.
- they must be abundant and highly widespread in the stratigraphic column.
