I believe its C because it seems the most reasonable.
Answer:
In this experiment, you changed the number of worms in the soil and measured the effect of this change on the plant growth in the population.

right on edge!
Some bacterial organisms are autotrophic, like the plant kingdom. They can also be single-cellular. They both have a cell membrane and some have a cell wall, like plant cells.
Answer:

Explanation:
Acceleration is the rate of velocity's change with time.
We can calculate it by dividing the change in velocity over time.

Let's define the variables. The final velocity is 15 meters per second. The initial velocity is 5 meters per second. The time is 5 seconds.

Substitute the values into the formula.

Solve the numerator first.

Divide.

The acceleration of the bus is <u>2 meters per second squared.</u>
