Question 1

If one tectonic plate slides under another, the process is known as:

Accepted Answer

Subduction

Answer

Subduction is a geological process where one tectonic plate moves under another and sinks into the mantle as the plates converge. This process is a fundamental part of plate tectonics and is associated with phenomena like volcanic activity and earthquakes.

Question 2

Plants are autotrophs, meaning that they:

Accepted Answer

Are able to produce their own food

Answer

Autotrophs are organisms that can produce their own food, typically using light (photosynthesis) or chemical energy (chemosynthesis). Plants are the primary example of autotrophs, converting sunlight into energy-rich organic compounds.

Question 3

Plant and animal cells both have cell membranes and nuclear membranes. However, plant cells have a structure that animal cells do not, known as a:

Accepted Answer

Cell Wall

Answer

While both plant and animal cells share many organelles like cell membranes, nuclei, mitochondria, and ribosomes, plant cells possess a rigid cell wall outside their cell membrane. This cell wall provides structural support and protection, a feature absent in animal cells.

Question 4

Muscles in the human body require what energy compound to function?

Accepted Answer

ATP

Answer

Muscles in the human body, like all living cells, require Adenosine Triphosphate (ATP) as their primary energy currency. ATP is produced through cellular respiration and is directly used to power muscle contraction and other cellular processes.

Question 5

If a bowling ball is pushed with 20 Newtons of force and has a mass of 4 kg, what is its initial acceleration?

Accepted Answer

5 m\/s^2

Answer

Newton's Second Law of Motion states that Force (F) equals Mass (m) times Acceleration (a), or F = ma. To find the acceleration, rearrange the formula to a = F/m. Given a force of 20 Newtons and a mass of 4 kg, the acceleration is 20 N / 4 kg = 5 m/s².
