Answer:

\boxed {\boxed {\sf 2. \ A \ computer \ that \ controls \ all \ activities }}

Explanation:

The nucleus of a cell is also called the control center of the cell. It contains all the instructions for protein synthesis and the genetic material.  Thus it also helps regulate the cell's activates.

Based on this information, we can assume it is like a computer that controls all activities.

It doesn't store materials, except DNA, it doesn't directly synthesize any molecules, and it doesn't produce energy.

External ear structure that helps to localize the direction from which sound arises
Step2247 [10]
The external ear structure is called the Pinna.

The Pinna helps to channel sound waves into the ear.

Many animals have the ability to move their pinna towards the direction of sound.

I have attached an image of a dog's ear to show you the external structure called the Pinna.

I hope this helps! I'm happy to answer any other questions you might have :)
