Explanation

Growth is physical and measurable (like height, weight), hence structural, and it stops at maturity.

Development is functional, involving cognitive, emotional, and social changes.

Development continues throughout life, even when physical growth stops.

Explanation

Let's simplify the expression:

tanθ + cotθ

= sinθ/cosθ + cosθ/sinθ

= (sin²θ + cos²θ) / (sinθcosθ)

Since sin²θ + cos²θ = 1:

= 1 / (sinθcosθ)

= 1/sinθ * 1/cosθ

= cosecθ * secθ

= secθcosecθ

Explanation

Given:

P(x) = x^2 - 4x + 3

One root is 1. Let's find the other root.

The sum of roots = -(-4) = 4 (from the coefficient of x)

One root is 1, so the other root would be:

4 - 1 = 3

Explanation

Given frequencies:

10–20 → 12

20–30 → 18

30–40 → 10

40–50 → 5

50–60 → 2

The minimum frequency is 2, which corresponds to class 50–60.

Explanation

"Who" is used as the subject of a sentence referring to a person.

The sentence is asking about the person performing the action (knocking).

Explanation

The correct sentence is: "This is the house she was referring to."

"The" is used here to refer to a specific house that is being discussed or identified.

Explanation

Compound adjective is formed when two or more words are combined to describe a noun, like "five-star" in this case.

It modifies the noun "hotel," describing the quality or rating of the services offered.

Explanation

The basic sentence structure in English is Subject-Verb-Object (SVO).

Example: She (S) eats (V) apples (O).

Explanation

An independent clause expresses a complete thought.

It can stand alone as a sentence.

It contains a subject and a predicate, making it grammatically complete.

Explanation

Socrates is famously known for the statement "Knowledge is virtue."

He believed that true knowledge leads to right action, and ignorance leads to wrongdoing.
