Explanation

Punishment involves applying a consequence (like benching) to reduce an undesirable behavior (poor performance).

It is used to discourage repetition of that behavior in the future.

Explanation

Glucose synthesis occurs during photosynthesis, which primarily happens in the leaves.

Leaves contain chlorophyll that captures sunlight energy needed for this process.

Explanation

Bacteria (e.g., Streptomyces) and Fungi (e.g., Penicillium) are commonly used to produce antibiotics.

These microorganisms naturally produce substances that kill or inhibit other microbes.

Explanation

Fe = 56, N = 14 × 2 = 28, O = 16 × 6 = 96 → Total = 56 + 28 + 96 = 180 amu

This is the correct formula mass for Iron (II) Nitrate, Fe(NO₃)₂.

Explanation

اسم معرفہ وہ اسم ہوتا ہے جو کسی خاص چیز، جگہ یا فرد کی نشاندہی کرے۔

Explanation

The Earth bulges at the equator and rotates, creating a centrifugal force that slightly reduces gravity there.

At the poles, this effect is minimal, so ‘g’ is stronger at the poles than at the equator.

Explanation

"Grew" here does not describe a physical action.

But instead connects the subject ("She") to its complement ("a lively young woman"), showing a state of transformation.

Linking verbs (e.g., become, seem, appear) tie the subject to a description or identity.

Unlike action verbs (e.g., run, jump).

Explanation

The sound level β (in dB) is given by:

β = 10 log(I / I₀)

where I₀ is the threshold intensity (faintest audible sound). Given I = I₀:

β = 10 log(1) = 0 dB

Explanation

The phrase "eating out" means having a meal outside the home, usually at a restaurant.

So, "We are eating out tonight" is correct.

Explanation

A spectrometer is an instrument used to measure the properties of light over a specific portion of the electromagnetic spectrum, especially to analyze line spectra produced by atoms or molecules.

It helps identify elements or compounds by detecting their unique emission or absorption lines in the spectrum.
