Explanation

If $\sin A=\sin B$, then:

A=B+360∘n or A=180∘−B+360∘n, where n ∈ Z

Let’s solve:

Case 1:

60∘+X=60∘⇒X=0∘

Case 2:

$$60^circ + X = 180^circ - 60^circ = 120^circ Rightarrow X = 60^circ$$

Possible values of X:

$$X = 0^circ quad text{or} quad X = 60^circ$$

Explanation

 CH₃COONH₄ – Salt of weak acid (acetic acid) and weak base (ammonia) → Can be slightly acidic, neutral, or basic depending on their relative strength, but usually basic if acetate dominates

Explanation

Use the Gibbs free energy equation:

$$\Delta G=\Delta H-T\Delta S$$

For a process to be spontaneous, $Delta G < 0$

• If $Delta H < 0$ (exothermic)

• And $Delta S > 0$ (entropy increases)

• Then:

  $$\Delta G=\text{negative}-T\times \text{positive}=\text{always negative}$$

 So, no matter the temperature, $Delta G$ will be negative ⇒ spontaneous at all temperatures

Explanation

Rudolf Virchow, in 1855, stated "Omnis cellula e cellular,"

Meaning "Every cell originates from another existing cell", reinforcing the cell theory.

Explanation

The element that is NOT a major bioelement but a trace element in living organisms is D) Zinc (Zn). 

Explanation

The Rydberg constant (R) is a physical constant used in atomic spectroscopy.

Its approximate value is 1.097×10^5 m-1  

Explanation

Circinate vernation, a term in botany, describes the arrangement of young leaves in a coiled or spiralled manner, characteristic of fern fronds. This coiled structure, often resembling a crozier or fiddlehead, protects the tender growing tip of the leaf as it matures. 

Explanation

The Kinetic Molecular Theory (KMT) is associated with James Clerk Maxwell. 

Explanation

Ribosomes bound to the surface of the endoplasmic reticulum give it a "rough" appearance, hence the term rough ER.

Explanation

 Paper chromatography works on the principle of adsorption and partition,

Where compounds are separated based on their movement through paper (stationary phase) with the help of a solvent (mobile phase).
