Math Physics Chemistry Biology QUESTION #11396

Proton donor✔️
Electron donor
Proton acceptor
Electron acceptor

Correct Answer Logic:

In photosynthesis, $CO_2$ acts as a proton donor (hydrogen acceptor) in the Calvin cycle. $CO_2$ is fixed by RuBisCO and combined with hydrogen (from NADPH) to form glucose. In this reduction process, $CO_2$ receives protons (H⁺) and electrons from NADPH, being reduced to carbohydrate. So $CO_2$ is reduced — it accepts protons/electrons.

Question 2

Sarojini Naidu's poem The Queen's Rival is based on a __________ legend.

Greek
Indian
Persian✔️
Roman

Correct Answer Logic:

Sarojini Naidu's poem The Queen's Rival draws on a Persian legend. The poem is set in an Oriental/Persian context and reflects Naidu's frequent engagement with Eastern — particularly Persian and Indian — mythological and cultural traditions in her poetry. Her collection The Bird of Time (1912) and The Broken Wing (1917) similarly draw on Eastern legends and imagery.

Law QUESTION #9491

Question 4

A's suit against B was dismissed for default when A failed to appear on the date of hearing. A applies for restoration, which is also dismissed. A then files a fresh suit on the same cause of action claiming the earlier dismissal was not on merits. B raises the plea of res judicata. Is the second suit barred?

Yes; dismissal for default operates as res judicata
No; but A must pay the costs of the previous suit
Yes; two dismissals operate as constructive res judicata
No; an order of dismissal for default is expressly excluded from the definition of 'decree' under the CPC and does not operate as res judicata✔️

Correct Answer Logic:

Section 2(2) CPC expressly provides that a decree shall not include 'any order of dismissal for default.' Dismissal for default is not a decision on merits. Therefore, it does not operate as res judicata, and a fresh suit on the same cause of action is maintainable, subject to limitation.

Question 8

How much $95\%$ alcohol is needed to prepare $500\text{ ml}$ of $70\%$ alcohol?

$368.4\text{ ml}$✔️
$350\text{ ml}$
$420.5\text{ ml}$
$300.0\text{ ml}$

Correct Answer Logic:

Using $C_1V_1 = C_2V_2$: $95 \times V_1 = 70 \times 500 \implies V_1 = 35000 / 95 \approx 368.4\text{ ml}$.

Question 14

The estimated number of alveoli in the human lungs is approximately:

150 million
500 million✔️
600 million
1 billion

Correct Answer Logic:

The human lungs contain approximately 500 million alveoli (range: 200–600 million), providing a total gas exchange surface area of ~70–100 m² — roughly the size of a tennis court. Each alveolus is a tiny air sac (~200–300 μm diameter) surrounded by capillaries. This enormous surface area, combined with the very thin alveolar-capillary membrane (~0.5 μm), enables efficient O₂/CO₂ exchange between air and blood.

Question 16

Immunological destruction of body tissue by antibodies reacting with it as if it were foreign antigen is called:

Anaphylaxis
Autoimmune diseases✔️
Prophylaxis
Immunodeficiency disease

Correct Answer Logic:

Autoimmune diseases occur when the immune system fails to distinguish self from non-self, producing antibodies (autoantibodies) or T-cells that attack the body's own tissues. Examples include rheumatoid arthritis, lupus (SLE), Type 1 diabetes, and multiple sclerosis. Anaphylaxis is a severe hypersensitivity reaction to an external antigen; prophylaxis is disease prevention; immunodeficiency involves reduced immune function.

Question 17

Transgenic stem cells are typically grown in:

Vitro✔️
Vivo
Ovary
Blastocyst

Correct Answer Logic:

Transgenic stem cells are grown in vitro (Latin: 'in glass') — in laboratory culture dishes or flasks, outside the living organism. This controlled environment allows manipulation, selection, and characterisation of transgenic clones. After in vitro propagation, transgenic stem cells may be injected into blastocysts or used for other in vivo applications. In vivo means within a living organism; the blastocyst is a stage, not a culture environment.

Question 19

During aerobic respiration, how many net ATP molecules are produced from the complete oxidation of one molecule of glucose?

30
32✔️
36
38

Correct Answer Logic:

The complete oxidation of one glucose molecule yields approximately $30$-$32$ ATP. Glycolysis yields $2$ ATP (net), the Krebs cycle yields $2$ ATP (via GTP), and oxidative phosphorylation yields about $26$-$28$ ATP from NADH and FADH$_2$. Modern estimates suggest $30$-$32$ ATP due to proton leak and shuttle costs.
