All numbers except 12 are odd multiples of 3. 12 is even.

Plastic is a polymer, while the others are metals.

The Crust is the outermost layer of the Earth, lying above the mantle.

First, evaluate A AND B which is 1 AND 1 = 1. Then NOT 1 = 0.

In this reaction, MnO4⁻ is reduced to Mn²⁺, thus it acts as the oxidizing agent.

The greenhouse effect is primarily caused by a combination of deforestation, industrial emissions, and agricultural practices that increase greenhouse gases in the atmosphere.

The biceps brachii is the primary muscle responsible for flexing the elbow joint.

The deltoid muscle is the primary muscle responsible for the abduction of the arm at the shoulder joint.

The minimum value of f(x) is -4 when x=0, so the range is [-4, ∞).

The function f(x) = x^2 is non-negative for all real x, hence the range is all non-negative real numbers.

The minimum value of |x - 1| is 0 when x = 1, so the range is [0, ∞).

Using the power of a power property, (a^m)^n = a^(m*n), we get (2^3)^2 = 2^(3*2) = 2^6.

Methane (CH4) is the simplest alkane, consisting of one carbon atom.

Ethylene (C2H4) is the simplest alkene, containing a double bond between two carbon atoms.

Acetylene (C2H2) is the simplest alkyne.

Methanoic acid (HCOOH) is the simplest carboxylic acid, containing only one carbon atom.

Dimethyl ether (CH3-O-CH3) is the simplest ether, consisting of two methyl groups bonded to an oxygen atom.

Acetone (propan-2-one) is the simplest ketone, with the formula (CH3)2CO.

The multiples of 7 are 7, 14, 21, 28, 35, 42, 49, 56, ... The smallest multiple greater than 50 is 56.

The smallest positive integer is 1.

Lakshadweep is the smallest Union Territory of India by area.

x + 2 > 1 => x > -1.

x + 2 > 7 => x > 5.

x + 5 > 2 => x > -3.

3x + 2 > 11 => 3x > 9 => x > 3.

3x + 2 ≥ 11 => 3x ≥ 9 => x ≥ 3.

x + 2 > 7 => x > 5.

Formic acid (HCOOH) is stronger than acetic acid (CH3COOH) due to the presence of a hydrogen atom directly attached to the carbonyl carbon, which stabilizes the conjugate base.

Formic acid (HCOOH) is the strongest carboxylic acid among the given options due to the presence of a hydrogen atom directly attached to the carbonyl carbon, which increases its acidity.

The truth table for an AND gate is: 00 -> 0, 01 -> 0, 10 -> 0, 11 -> 1.
