MBBS QUESTION #10286

Question 3642

A patient with polyuria and polydipsia fails to concentrate urine during a water deprivation test but responds appropriately (urine osmolality rises) after administration of exogenous desmopressin (an ADH analogue). This pattern is most consistent with:

Central (neurogenic) diabetes insipidus✔️
Nephrogenic diabetes insipidus
Primary polydipsia
Uncontrolled diabetes mellitus

Correct Answer Logic:

Central diabetes insipidus results from inadequate hypothalamic-pituitary ADH secretion; because the renal collecting duct receptors are intact, administering exogenous ADH (desmopressin) restores urine concentrating ability — in contrast to nephrogenic DI, where renal resistance to ADH means desmopressin produces little or no response.

Mathematics QUESTION #4109

Question 3644

Let $\mathbb{Q}^+$ be the set of positive rational numbers with operation $a * b = \frac{ab}{2}$. What is the identity element $e$ such that $a * e = a$ for all $a \in \mathbb{Q}^+$?

$e = 0$
$e = 1$
$e = 2$✔️
$e = \frac{1}{2}$

Correct Answer Logic:

For identity: $a * e = \frac{ae}{2} = a$, so $ae = 2a$, thus $e = 2$.

MBBS QUESTION #10230

Question 3646

During the rising (depolarization) phase of a neuronal action potential, the rapid change in membrane potential is primarily due to:

Opening of voltage-gated Na+ channels and rapid Na+ influx✔️
Opening of voltage-gated K+ channels and K+ efflux
Inactivation of the Na+/K+-ATPase pump
Ca2+ influx through voltage-gated calcium channels

Correct Answer Logic:

Depolarization beyond threshold opens voltage-gated Na+ channels, producing a rapid, regenerative Na+ influx that drives the membrane potential toward the Na+ equilibrium potential — the hallmark rising phase of the action potential, later terminated by Na+ channel inactivation and delayed K+ channel opening (repolarization).

$y = 0.9 - 9.4x$
$y = 9.4 + 0.9x$
$y = 9.4 - 0.9x$✔️

Correct Answer Logic:

A negative linear trend requires a negative slope. Option 4 has a negative slope ($-0.9$) and a reasonable intercept.

Question 3657

The evolution of ecologically related species is sometimes co-ordinated such that each species exerts a strong selective influence on others. This is:

Coexistence
Coevolution✔️
Mutualism
None of these

Correct Answer Logic:

Coevolution is the process by which two or more species reciprocally affect each other's evolution through natural selection. Classic examples include plant-pollinator relationships, predator-prey arms races, and host-parasite interactions. Mutualism is a type of symbiosis (both benefit) that can result from coevolution, but coevolution is the broader evolutionary process.

Economics QUESTION #1692

Question 3658

In the IS-LM model of macroeconomic equilibrium, the LM curve traces out all combinations of income and interest rates at which:

The goods and services market is in equilibrium
The government budget is balanced
The money market (financial market) is in equilibrium✔️
None of these

Correct Answer Logic:

The LM curve (L = Liquidity preference, M = Money supply) represents all combinations of real income (Y) and interest rate (r) at which the money market is in equilibrium — where money demand equals money supply ($L(Y, r) = M/P$). As income rises, money demand increases, requiring a higher interest rate to maintain equilibrium. The IS curve represents equilibrium in the goods market.
