Question 123

Which of the following is the dominant generation in the life cycle of Pteridophytes?

Sporophyte✔️
Gametophyte
Seedling
Embryo

Correct Answer Logic:

In pteridophytes (ferns and allies), the sporophyte generation (diploid, 2n) is the dominant, independent, and conspicuous phase — the familiar leafy fern plant. The gametophyte (haploid, n) is a small, inconspicuous, short-lived prothallus. This contrasts with bryophytes where the gametophyte is dominant, and represents an evolutionary advancement.

Physics QUESTION #1028

Question 124

Three identical heat conducting rods in series: outer rods have conductivity \(2K\), middle rod has conductivity \(K\). Left end at \(3T\), right end at \(T\). The ratio \(T_1/T_2\) (left junction to right junction temperature) is:

\(\dfrac{5}{3}\)✔️
\(\dfrac{5}{4}\)
\(\dfrac{3}{2}\)
\(\dfrac{4}{3}\)

Correct Answer Logic:

In steady state, heat flow rate \(Q\) is same through all rods. Let each rod have length \(L\) and area \(A\). \(\frac{2KA(3T-T_1)}{L} = \frac{KA(T_1-T_2)}{L} = \frac{2KA(T_2-T)}{L}\). From 1st and 3rd: \(2(3T-T_1)=2(T_2-T)\Rightarrow 3T-T_1=T_2-T\Rightarrow T_1+T_2=4T\). From 1st and 2nd: \(2(3T-T_1)=T_1-T_2\Rightarrow 6T-2T_1=T_1-T_2\Rightarrow 3T_1-T_2=6T\). Solving: \(T_1=\frac{5T}{2}, T_2=\frac{3T}{2}\). Ratio \(=\frac{5/2}{3/2}=\frac{5}{3}\).

\(\dfrac{1}{6}\)

Correct Answer Logic:

Numbers greater than 4: {5, 6} → 2 outcomes out of 6. Probability \(= \dfrac{2}{6} = \dfrac{1}{3}\).

Statistics QUESTION #1994

Question 133

If sampling is done with replacement from a population with mean \(\mu = 4\) and variance \(\sigma^2 = \frac{20}{9}\), then by Chebyshev's theorem, the probability that the sample mean \(\bar{X}\) (for \(n = 36\)) lies between 3.26 and 4.74 is AT LEAST:

\(0.75\)✔️
\(0.95\)
\(0.50\)
\(0.68\)

Correct Answer Logic:

Here \(\sigma_{\bar{X}}^2 = \sigma^2/n = (20/9)/36 = 20/324\), so \(\sigma_{\bar{X}} = \sqrt{20}/18\). The interval \((3.26, 4.74)\) is \(\mu \pm 0.74\). Then \(k = 0.74/\sigma_{\bar{X}}\). Chebyshev gives \(P(|\bar{X}-\mu|\leq k\sigma_{\bar{X}}) \geq 1 - 1/k^2\). With \(k^2 = 4\), the lower bound is \(1 - 1/4 = 0.75\).
