Explanation

The production of ammonia in industry, specifically through the Haber process, can be increased by raising the pressure.

Higher pressure shifts the equilibrium towards more ammonia production, though temperature and catalysts also play a role.

Explanation

To determine the smallest fraction among 17/23, 14/15, 15/19, and 16/21, we compare their decimal values:

17 ÷ 23 ≈ 0.7391

14 ÷ 15 ≈ 0.9333

15 ÷ 19 ≈ 0.7895

16 ÷ 21 ≈ 0.7619

17/23 ≈ 0.7391 is the smallest among the given fractions.

The smaller the decimal value, the smaller the fraction.

Explanation

In a compound microscope, the final image is typically virtual and inverted.

The objective lens forms a real, inverted image, which is then magnified by the eyepiece, resulting in a virtual and inverted image seen by the observer.

Explanation

Ignoring game rules increases the risk of accidents and injuries.

Rules are designed to ensure safety and fair play in sports.

Explanation

The occipital lobe of the brain processes visual information received from the eyes.

It interprets signals related to color, shape, and motion, enabling vision.

Explanation

This range of mountains is very high.

"Range" is the singular subject, so the singular verb "is" is used.

Even though "mountains" is plural, it is part of a prepositional phrase and does not affect the verb agreement.

Explanation

The parents asked them to pray to ALLAH for his recovery.

In indirect speech, "said" changes to "asked" when making a request.

The verb "to pray" remains in its base form, ensuring correct grammar.

Explanation

A stadiometer is specifically designed to measure a person's height accurately.

It typically consists of a vertical ruler with a movable headpiece for precise measurement.

Explanation

The pulse can be felt at arterial sites where blood is pumped through arteries, such as the wrist (radial artery) or neck (carotid artery).

Arterial sites provide a direct measurement of the heartbeat through the artery's rhythm.

Explanation

In a series circuit, the same current flows through all resistors because there is only one path for the current.

The total resistance is the sum of individual resistances, but the current remains unchanged throughout the circuit.
