Explanation

A dressing is primarily used to:

• Control bleeding by applying pressure.
• Cover the wound to prevent contamination and infection.

Options B (Close airway) and C (Stop body fluid flow) are incorrect

Explanation

In a renal transplant, regulating protein intake is crucial to minimize strain on the transplanted kidney.

Excessive protein consumption can lead to complications such as proteinuria and kidney damage.

Explanation

Metalloids are known to have electronic band structures that are similar to semimetals or semiconductors.

Metalloids are known to form amphoteric or weakly acidic oxides.

These elements have the ability to form metallic alloys.

Explanation

A transformer operates on the principles of “electromagnetic induction”, in the form of Mutual Induction.

Mutual induction is the process by which a coil of wire magnetically induces a voltage into another coil located in close proximity to it.

Explanation

three  classes of Levers

• Class One Lever
• Class Two Lever
• Class Three
• The force placed between the load and the fulcrum is called Class Three Lever
• ***

• The fulcrum placed between the force and load is called Class One Lever
• ***

Explanation

3 % of Earth's water is fresh.

2.5% of the earth's freshwater is unavailable:

locked up in glaciers,

polar ice caps,

atmosphere,

and soil;

lies too far under the earth's surface to be extracted at an affordable cost.

0.5% of the earth's water is available in freshwater.

Explanation

The 6th period of the modern periodic table contains 32 elements.

This period is known as the "extended" period and includes elements from the Lanthanide series. 

It is the longest period of the periodic table

Explanation

The telencephalon is the part of the developing brain that eventually forms the cerebral hemispheres.

The term "cerebral hemispheres" is synonymous with the telencephalon. 

Explanation

If a codon consisted of only two nucleotides, there would be 16 possible codons. 

Since there are four possible nucleotides (A, C, G, and T), each position in a two-nucleotide codon could be filled by any of these nucleotides.

Therefore, to calculate the total number of possible codons,

We multiply the number of possibilities for the first position by the number of possibilities for the second position:

4 nucleotides * 4 nucleotides = 16 possible codons. 

Explanation

At room temperature, H₂ (hydrogen) has the lowest density among Ne (neon), N₂ (nitrogen), and CO (carbon monoxide). 

Density is directly proportional to molar mass, meaning the gas with the lowest molar mass will have the lowest density.

Hydrogen has the lowest molar mass among the listed gases, making it the least dense.
