It helps in building immunity against poliomyelitis.

Explanation

Dinoflagellates do have cellulose plates, but not impregnated with calcium — that’s a feature of some other protists, not typical dinoflagellates.

They are mostly unicellular and can form blooms (like red tides).

Explanation

1,2-Butadiene contains cumulene structure with adjacent double bonds (C=C=C), leading to sp-hybridization at the central carbon.

The terminal carbon atoms are sp²-hybridized, while the central carbon is sp-hybridized.

Explanation

Hormones are chemical messengers that travel through the bloodstream to target organs and tissues.

This is a key function of the circulatory system, helping regulate various bodily functions.

Explanation

An Intelligence Test measures a person’s overall mental capacity and cognitive abilities.

It assesses reasoning, problem-solving, and understanding skills.

Explanation

The X-axis and Y-axis intersect at the point (0, 0), known as the origin.

It is the central reference point in the coordinate plane.

Explanation

Restoring force 𝐹 = −𝑘𝑥 depends on displacement 𝑥.

At the mid position, x = 0, so restoring force is minimum (zero).

Explanation

Step 1: Convert binary numbers to decimal for easier calculation

(101)2 = 1 × 2^2 + 0 × 2^1 + 1 × 2^0 = 4 + 0 + 1 = 5

(110)2 = 1 × 2^2 + 1 × 2^1 + 0 × 2^0 = 4 + 2 + 0 = 6

Step 2: Add the decimal values

5 + 6 = 11

Step 3: Convert the sum back to binary

11 = 8 + 2 + 1 = 2^3 + 2^1 + 2^0 = (1011)2

Explanation

LCM of two prime numbers is their product, since they have no common factors other than 1.

So, LCM(a, b) = a × b when both a and b are prime.

Explanation

The Great Bath of Mohenjo-Daro dates back to around 2600 BCE, making it about 4300 years old.

It is one of the earliest known public water tanks in the world.
