Explanation

Diagnostic assessment is used to identify students' current knowledge, skills, and learning gaps before instruction begins.

It helps teachers plan appropriate lessons based on each student's existing learning level.

Explanation

In this reaction, two reactants (CaO and CO₂) combine to form a single product (CaCO₃).

This is the definition of a combination (or synthesis) reaction.

Explanation

Tom has 3 more marbles than Bob.

Bob has 10 marbles, so Tom has 10 + 3 = 13 marbles.

So the correct equation is:

∆ - 3 = 10 (Because if Tom has ∆ marbles, and we subtract 3, it equals Bob's 10 marbles.)

Explanation

Bus width affects how much data can be transferred at once.

System clock speed controls how fast instructions are processed.

Memory access time determines how quickly data can be read/written.

Explanation

Carbon dioxide (CO₂) is a major greenhouse gas that helps trap heat in the Earth’s atmosphere.

It plays a key role in maintaining Earth’s temperature but excess CO₂ leads to global warming.

Explanation

In cellular respiration, glucose (food) is broken down in cells (via mitochondria) to produce ATP (energy), CO₂, and water.

Chemical equation: C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + Energy (ATP)

Explanation

Explanation

User-defined functions are those that are created by the programmer to perform specific tasks.

Unlike pre-defined functions, they offer custom behavior and improve code reusability and structure.

Explanation

Let's use the Pythagorean theorem to find the distance between the school and the market:

School (north) = 9m

Market (east) = 12m

Distance² = 9² + 12²

= 81 + 144

= 225

Distance = √225

= 15m
