Biology Zoology Botany QUESTION #1352

The portion of the digestive tract of a pigeon that produces 'pigeon's milk' used in feeding young is the:

Proventriculus
Gizzard
Crop✔️
None of these

Correct Answer Logic:

The crop is the enlarged pouch in the oesophagus of pigeons and doves. During the breeding season, the crop lining of both parents proliferates under the influence of prolactin to produce 'pigeon milk' — a protein- and fat-rich secretion regurgitated to feed nestlings. The proventriculus is the glandular stomach and the gizzard is the muscular grinding stomach.

Chemistry QUESTION #7502

Question 190

Match the compounds in Item I with their correct detection reagents in Item II:

Item I (Compound)	Item II (Reagent)
(A) Lysine	(P) 1-naphthol
(B) Furfural	(Q) Ninhydrin
(C) Benzyl alcohol	(R) KMnO$_4$
(D) Styrene	(S) Ceric ammonium nitrate

(A)→(Q); (B)→(P); (C)→(S); (D)→(R)✔️
(A)→(Q); (B)→(P); (C)→(R); (D)→(S)
(A)→(R); (B)→(P); (C)→(Q); (D)→(S)
(A)→(Q); (B)→(R); (C)→(S); (D)→(P)

Correct Answer Logic:

Matching logic:

Lysine is an amino acid — detected by ninhydrin (Q), which gives a purple colour with primary amines/amino acids.
Furfural is an aldehyde from furan — detected by 1-naphthol (P) via the Tollens-type or colour reaction specific to furfural.
Benzyl alcohol (PhCH$_2$OH) is a primary alcohol — detected by ceric ammonium nitrate (S), which gives a red colour with alcohols.
Styrene (Ph–CH=CH$_2$) has a C=C bond — oxidized by KMnO$_4$ (R), which gets decolourized.

Correct match: (A)→(Q), (B)→(P), (C)→(S), (D)→(R)

Civil / Architecture QUESTION #2346

Question 195

For a normally consolidated clay layer of thickness $H$, compression index $C_c$, initial void ratio $e_0$, initial effective overburden stress $\sigma'_0$, and stress increase $\Delta\sigma'$, the primary consolidation settlement $S_c$ is:

$S_c = \dfrac{C_s H}{1 + e_0} \log\!\left(\dfrac{\sigma'_0 + \Delta\sigma'}{\sigma'_0}\right)$
$S_c = \dfrac{C_c H}{1 + e_0} \ln\!\left(\dfrac{\sigma'_0 + \Delta\sigma'}{\sigma'_0}\right)$
$S_c = \dfrac{C_c H}{1 + e_0} \log\!\left(\dfrac{\sigma'_0 + \Delta\sigma'}{\sigma'_0}\right)$✔️
$S_c = m_v \cdot H \cdot \Delta\sigma'$

Correct Answer Logic:

For normally consolidated clay: $S_c = \dfrac{C_c H}{1 + e_0} \log_{10}\!\left(\dfrac{\sigma'_0 + \Delta\sigma'}{\sigma'_0}\right)$. The compression index $C_c$ applies for stresses exceeding the preconsolidation pressure. For over-consolidated clay (within the preconsolidation range), the recompression index $C_s \approx C_c/5$ to $C_c/10$ is used instead (Option A).

Boilers Mechanical Engineering QUESTION #2413

Question 200

For a floating or submerged body, stability requires that the metacentric height $GM$ satisfies:

$GM < 0$ (overturning moment)
$GM > 0$ (righting moment — metacenter M above center of gravity G)✔️
$GM = 0$ (neutral stability only)
$GM$ must equal the center of buoyancy height

Correct Answer Logic:

Stability: metacentric height $GM=KB+BM-KG>0$ for stable equilibrium. When $GM>0$, any heel generates a righting moment restoring the body to upright.
