When a volcano erupts, its actions are similar to which of the following events?

A. A food eroding the banks of a stream

B. A can of soda fling when it is opened

C. A tree root pushing up through the pavement

D. A building burning to the ground

Answer Explanation:

Both involve the release of pressure from a confined space. In the case of a volcano, pressure builds up beneath the Earth's surface, causing an eruption. Similarly, when a can of soda is opened, the release of pressure inside the can causes the soda to fizz and potentially spray out.

Therefore, the Correct Answer is B.

Q #1: Which of the following expressions represents the sum of three times a number and eight times a different number?

A. 3x+8y

B. 8x+3x

C. 3x-8y

D. 8x-3y

Answer Explanation

Let two numbers be x and y. Then

Three-time a number=3x

Eight times a different number = 8y

The sum of the two is 3x+8y
Q #2: Water molecules enter cells by which of the following transport mechanisms?

A. Gated channels

B. Proton pumps

C. Facilitated diffusion

D. the following transport mechanisms?

Answer Explanation

Water molecules are polar and cannot easily cross the hydrophobic lipid bilayer of the cell membrane. They use aquaporins, which are water channels that allow water to pass through.
Q #3: When a volcano erupts, its actions are similar to which of the following events?

A. A food eroding the banks of a stream

B. A can of soda fling when it is opened

C. A tree root pushing up through the pavement

D. A building burning to the ground

Answer Explanation

Both involve the release of pressure from a confined space. In the case of a volcano, pressure builds up beneath the Earth's surface, causing an eruption. Similarly, when a can of soda is opened, the release of pressure inside the can causes the soda to fizz and potentially spray out.
