The uterus is the hollow, thick-walled muscular organ where implantation of the fertilised egg and foetal development occur. It is positioned in the pelvic cavity anterior to the rectum and posterior to the urinary bladder. The uterine (Fallopian) tubes open into its superior angles. The cervix is the lower, narrow portion of the uterus; the vagina is the birth canal; the endometrium is the inner lining of the uterus.

Question 7084

The age of Hazrat Usman (RA) at the time of his martyrdom was:

80✔️
78
76
74

Correct Answer Logic:

CISA QUESTION #1782

Question 7085

What is the most significant concern when deploying computer-assisted audit tools (CAATs)?

The technical capability of the software vendor
Potential costs, complexity of implementation, and security of the output✔️
The inability of automated tools to account for human behavioral factors
Documentary evidence being more reliable than automated results

Correct Answer Logic:

While CAATs can process data faster and more accurately than manual review, the primary concerns center on cost of acquisition and training, the complexity of proper deployment, and ensuring that the output is adequately secured and protected from unauthorized access or tampering.

Question 7088

The Soderberg criterion for fatigue is more conservative than the modified Goodman criterion because it uses which strength in place of $S_{ut}$?

Endurance limit $S_e$
Proof strength $S_p$
Yield strength $S_y$✔️
Fracture strength $S_f$

Correct Answer Logic:

The Soderberg criterion: $\frac{\sigma_a}{S_e}+\frac{\sigma_m}{S_y}=\frac{1}{n}$. It substitutes yield strength $S_y$ for ultimate strength $S_{ut}$. Since $S_y < S_{ut}$, the Soderberg line falls inside the Goodman line, making it more conservative.

Chemistry QUESTION #5566

Question 7090

$[3Ca_3(PO_4)_2 \cdot CaF_2]$✔️
$[3\{Ca(OH)_2\} \cdot CaF_2]$
$[CaF_2]$
$[3(CaF_2) \cdot Ca(OH)_2]$

Correct Answer Logic:

Fluoride ions replace the hydroxide ions in hydroxyapatite: $3Ca_3(PO_4)_2 \cdot Ca(OH)_2 + 2F^- \to 3Ca_3(PO_4)_2 \cdot CaF_2 + 2OH^-$. The product, fluoroapatite $[3Ca_3(PO_4)_2 \cdot CaF_2]$, is harder and more resistant to acid attack than hydroxyapatite, thus protecting teeth from decay.

Question 7091

Diacetyl, the primary butter flavor compound, is produced by which metabolic pathway?

Lactose fermentation via glycolysis directly
Citrate fermentation by $Leuconostoc\;mesenteroides$ and $Lactococcus\;lactis$ subsp. $lactis$ biovar $diacetylactis$: citrate $\rightarrow$ pyruvate $\rightarrow$ $\alpha$-acetolactate $\rightarrow$ diacetyl✔️
Proteolysis of casein releasing sulfur compounds
Lipolysis releasing short-chain fatty acids

Correct Answer Logic:

Diacetyl (2,3-butanedione) is the key aroma compound in cultured butter and sour cream. It is produced from citrate (present in milk at $\approx 8\;\text{mM}$) via: citrate $\rightarrow$ pyruvate $\rightarrow$ $\alpha$-acetolactate $\rightarrow$ diacetyl.

Mathematics QUESTION #11206

Question 7092

Which of the following is NOT true for an Abelian group $G$?

$[a,b] = e\;\forall\,a,b\in G$
$G$ is a simple group of order 60✔️
$G' = \{e\}$
$Z(G) = G$

Correct Answer Logic:

For an abelian group: (A) commutator $[a,b]=aba^{-1}b^{-1}=e$ ✓ (true for abelian); (C) $G' = \{e\}$ (derived subgroup is trivial) ✓; (D) $Z(G)=G$ (every element commutes) ✓. Statement (B) '$G$ is a simple group of order 60' is NOT necessarily true — the simple group of order 60 is $A_5$, which is non-abelian. An abelian simple group has prime order, not order 60.

Question 7093

One light year is equal to:

9 x 10^12 m
6 x 10^12 m
9.5 x 10^13 m✔️
None

Correct Answer Logic:

One light year is the distance light travels in one year = 9.461 x 10^15 m ≈ 9.5 x 10^15 m. The closest answer is 9.5 x 10^13 m (option C as given in paper).

Question 7096

Kyanite is a polymorph of which mineral group (sharing the formula $\text{Al}_2\text{SiO}_5$)?

Sillimanite✔️
Cerussite
Siderite
None of these

Correct Answer Logic:

Kyanite, sillimanite, and andalusite are three polymorphs of $\text{Al}_2\text{SiO}_5$ — same chemical formula, different crystal structures.

Kyanite: triclinic, high pressure, low–medium temperature
Andalusite: orthorhombic, low pressure, low–medium temperature
Sillimanite: orthorhombic, high temperature

Their stability fields on P–T diagrams define metamorphic grade and are critical geothermobarometers.

Physics QUESTION #1040

Question 7097

A container with $V_1=2\ \text{L},\ n_1=5\ \text{mol},\ p_1=1\ \text{atm}$ and $V_2=3\ \text{L},\ n_2=4\ \text{mol},\ p_2=2\ \text{atm}$ is separated by a thermal insulator. When partition is removed, equilibrium pressure is:

1.4 atm
1.8 atm
1.3 atm
1.6 atm✔️

Correct Answer Logic:

Since the partition is a thermal insulator, after mixing the total internal energy is conserved. For ideal gas: $U \propto nT$. From ideal gas law: $T_1=\frac{p_1V_1}{n_1R}=\frac{1\times2}{5R}=\frac{2}{5R}$ and $T_2=\frac{2\times3}{4R}=\frac{6}{4R}$. Final $T_f = \frac{n_1T_1+n_2T_2}{n_1+n_2}=\frac{5\cdot\frac{2}{5R}+4\cdot\frac{6}{4R}}{9}=\frac{\frac{2}{R}+\frac{6}{R}}{9}=\frac{8}{9R}$. Final $p=\frac{(n_1+n_2)RT_f}{V_1+V_2}=\frac{9R\cdot\frac{8}{9R}}{5}=\frac{8}{5}=1.6\ \text{atm}$.

Electrical Engineering QUESTION #2136

Question 7100

According to Tellegen's Theorem, for any network with $b$ branches and $n$ nodes, the algebraic sum of power delivered to all branches at any instant is:

Always positive
Dependent on the type of elements
Zero✔️
Equal to the total energy stored

Correct Answer Logic:

Tellegen's Theorem is based on KCL and KVL; it states that $\sum_{k=1}^{b} v_k i_k = 0$, meaning the sum of power delivered to all branches in a network is zero.
