RUHS B.Sc Nursing Questions from 2025

The questions asked in RUHS BSc 2025 are mentioned here, subject-wise:

Physics

Question 1: The barrier potential in a P-N junction is maximum in:
(A) The forward bias condition
(B) The reverse bias condition
(C) zero-bias condition
(D) When the diode is used as rectifier

Answer: reverse bias condition - The correct answer is option B

Explanation: Reverse bias widens the depletion region, increasing the barrier potential.

Question 2: The resistance of a wire is 5Ω at 50°C and 6Ω at 100°C. Its resistance at 0°C will be:
(A) 1Ω
(B) 2Ω
(C) 3Ω
(D) 4Ω

Answer: 3Ω - The correct answer is option C

Explanation: $R_T = R_0(1 + \alpha T)$. Solve for $R_0$ using the given resistances.

Question 3: If resonance frequency is $f$ and capacitance increases $4$ times, the new resonance frequency is:
(A) $4f$
(B) $2f$
(C) $f/2$
(D) $f$

Answer: $f/2$ — The correct answer is option C.

Explanation: $f = \dfrac{1}{2\pi\sqrt{LC}}$. If $C$ becomes $4C$, then $f_{\text{new}} = f/2$.

Chemistry

Ques:1
Which of the following vitamins is water-soluble?

Options:
A. Vitamin A
B. Vitamin D
C. Vitamin K
D. Vitamin C

Correct Answer:
D. Vitamin C

Explanation:
Vitamins are categorised into two types based on their solubility: fat-soluble and water-soluble.

• Fat-soluble vitamins include A, D, E, and K, which are stored in the body’s fatty tissues and liver.

• Water-soluble vitamins, such as Vitamin C and B-complex vitamins, dissolve in water and are not stored in the body, meaning they need to be consumed more regularly.

Vitamin C (ascorbic acid) is a classic water-soluble vitamin, essential for tissue repair, the enzymatic production of certain neurotransmitters, and immune function.

Ques:2
Which acid is present in vinegar?

Options:
A. Formic acid
B. Lactic acid
C. Citric acid
D. Acetic acid

Correct Answer:
D. Acetic acid

Explanation:
Vinegar is a sour-tasting liquid primarily composed of acetic acid (CH₃COOH) and water. It is produced through the fermentation of ethanol by acetic acid bacteria. While the concentration of acetic acid in vinegar typically ranges from 4% to 8%, this is what gives vinegar its distinctive pungent smell and sour taste.

• Formic acid is found in ant stings.

• Lactic acid is produced in muscles during intense activity and is present in sour milk products.

• Citric acid is found in citrus fruits like lemons and oranges.

Biology

Ques:1 Histone proteins are rich in:

(A) Aspartic acid and glutamic acid
(B) Alanine and isoleucine
(C) Proline and valine
(D) Lysine and arginine

Correct Option:
(D) Lysine and arginine

Explanation:
Histone proteins are positively charged due to a high content of basic amino acids like lysine and arginine. This positive charge allows histones to bind tightly to the negatively charged phosphate backbone of DNA, facilitating DNA packaging in the nucleus into structures called nucleosomes. This interaction is essential for chromatin structure and gene regulation.

Ques: 2 The DNA sequence that provides the binding site for RNA polymerase is called:

(A) Promoter site
(B) Operator site
(C) Terminator site
(D) Structural site

Correct Option:
(A) Promoter site

Explanation:

The promoter site is a specific DNA sequence where RNA polymerase binds to initiate transcription. It is located upstream of the coding region of a gene and contains specific motifs like the TATA box in eukaryotes. This region ensures that RNA polymerase starts transcription at the correct location. Other sites, like the operator, regulate transcription (especially in prokaryotes), the terminator signals transcription to stop, and the structural site refers to the actual coding region of the gene.

Ques: 3 Which cell is responsible for androgen secretion?

(A) Cervoli cells
(B) Interstitial cells
(C) Leydig cells
(D) Sperm

Correct Option:

(C) Leydig cells

Explanation:

Leydig cells, also known as interstitial cells, are located in the spaces between the seminiferous tubules of the testes. These cells are responsible for the production and secretion of androgens, primarily testosterone. This process is regulated by luteinizing hormone (LH) from the anterior pituitary gland. The testosterone secreted by Leydig cells plays a vital role in the development of male secondary sexual characteristics and the maintenance of spermatogenesis.

Ques: 4 Embryological support for evolution was proposed by:

(A) Alfred Wallace
(B) Ernst Haeckel
(C) Charles Darwin
(D) Ugo de Vries

Correct Option:

(B) Ernst Haeckel

Explanation:

Ernst Haeckel proposed the idea that embryological development in different species shows similarities that reflect their evolutionary ancestry. He formulated the “biogenetic law,” often summarised as "ontogeny recapitulates phylogeny," which suggested that the development of an organism (ontogeny) retraces the evolutionary history (phylogeny) of its species. While the strict interpretation of this idea has been discredited, comparative embryology remains an important line of evidence for common descent.
