Refer to the picture below. This is an example of:
Sedbober [7]

Answer:

The answer is a. homologous structures

Explanation:

Homologous Structures:

Structures that have<u> similar anatomy or similar structure</u> but have different functions are called homologous structures.

These structures indicate shared ancestry between the animals in question. This means that the structures may be used for different functions but they are encoded by same or similar genes.

The bones in the picture perform quite different functions and they might look different from the outside but as we look closer, the bone structure and joints are similar. This shows that all of these animals evolved from a common ancestor.

Explain why you would sooner be hit by a ping pong ball vs a baseball. Use all the terms: force mass and acceleration!!
kati45 [8]

Answer:

Because the ping pong ball has a lesser mass than a baseball; hence the ping pong ball will accelerate faster than the baseball when a constant force is applied to both

Explanation:

The force applied to an object is a product of its mass and acceleration i.e. F=ma. According to Newton's second law of motion, the relationship between the mass of an object and its acceleration when force is applied to it was described.

In a summary, the second law states that that the acceleration of an object increases with increased force and decreases with increased mass. This means that the more the mass of an object, the greater the force needed to make it accelerate and also the more the mass, the lesser it accelerates.

In this case, a ping pong ball has a lesser mass compared to a baseball, hence, it will accelerate faster than the baseball assuming an equal force was applied. Since the ping pong ball will accelerate faster, it will hit a person faster than the baseball.
