No they have eukaryotic cells
Answer: 4.speed
Explanation:
In this case, we know that the cart remains at a constant 20km/h.
Now, one could say that "the velocity remains constant, because it always is 20km/h"
But remember that velocity is a vector, so this has a direction, and if the cart is going around a turn, then the direction of motion is changing, which tell us that there is acceleration.
But the module of the velocity, the speed, remains constant at 20km/h.
Then the correct option is 4, speed.
The correct answer is:
That the land where it specifically was has been moving and that years ago that place was under water.
Explanation:
Kansas has been the cause of some of the most luxurious fossil findings in US history. The fossil record of Kansas spans from the Cambrian to the Pleistocene. From the Cambrian to the Devonian, Kansas was coated by a shallow sea.
Mechanical waves require a medium to travel, but electromagnetic waves do not.
Explanation:
By one dimension, one means motion along a line, or in one particular direction. Think of a car going down a straight road, or a person running on a straight track.
...
1. Motion in one dimension
2. Average velocity.
3. Instantaneous velocity.
