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>

Explanation: The birds have to adapt to the different environments, so that means that their beaks - as well as other body features will differ, based on what type of environment the bird lives in and how it survives
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
