Explanation

Monosaccharides are the building blocks of disaccharides (such as sucrose, lactose, and maltose) and polysaccharides (such as cellulose and starch).

A glycosidic bond is a covalent bond that connects two monosaccharides to form a disaccharide or polysaccharide. 

Explanation

The triple point of water is the unique temperature and pressure at which water coexists in all three phases — solid, liquid, and gas — in equilibrium.

Temperature: 273.16 Kelvin

This is used as a fundamental fixed point in defining the Kelvin temperature scale.

Explanation

A strong oxidizing agent has a greater Reduction potential. 

An oxidizing agent readily accepts electrons, which corresponds to a high reduction potential.

A higher reduction potential indicates a greater tendency for a substance to be reduced (gain electrons) and thus act as an oxidizing agent. 

Explanation

I buried him two days ago.

The phrase “two days ago” clearly indicates a specific time in the past, so we must use the simple past tense.

"Buried" is the simple past form of the verb "bury."

Explanation

This refers to the loss of water through the cuticle, the waxy layer on the surface of leaves. 

Sources consistently state that approximately 5-7% of total transpiration occurs via the cuticle. 

Explanation

The average translational kinetic energy of a molecule in an ideal gas is given by the formula:

E=3/2​kT

Where:

• $k = 1.38 times 10^{-23} , text{J/K}$ (Boltzmann constant)

• T=27∘C=300K (since 27°C + 273 = 300 K)

Now calculate:

E=3​/2×1.38×10^−23×300
E=3/2​×4.14×10^−21

6.21×10^−21 J

Explanation

The pair that is not isomorphous is Na₂CO₃, CaCO₃. 

While both compounds have similar chemical formulas.

The difference in ionic radii between sodium and calcium leads to different crystal structures, making them not isomorphous.

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

I have never known him for a long time.

میں اسے ایک عرصے سے کبھی نہیں جانتا تھا۔

"Have never known" is the correct present perfect tense.

It indicating that up until now, the speaker has never known the person.

Explanation

 I was reading a novel when they came to see me.

This is a case of a past continuous action interrupted by a simple past action:

"I was reading a novel" → Past continuous (ongoing action)

"They came to see me" → Simple past (interrupting event)

This is a common structure in English: Past Continuous + when + Simple Past
