MBBS QUESTION #10314

Question 7763

Linoleic acid and alpha-linolenic acid are termed 'essential' fatty acids because humans must obtain them from the diet, as human cells lack the enzymes needed to:

Elongate fatty acid carbon chains
Introduce double bonds beyond the delta-9 position — i.e., desaturate fatty acids at the omega-6 and omega-3 positions✔️
Beta-oxidize fatty acids for energy
Esterify fatty acids onto a glycerol backbone

Correct Answer Logic:

Human desaturase enzymes can introduce double bonds only up to the delta-9 position; the further desaturation needed to place double bonds at the omega-6 (linoleic acid) or omega-3 (alpha-linolenic acid) positions is absent in humans, making these fatty acids dietary-essential precursors for eicosanoid and membrane lipid synthesis.

Electronics Engineering QUESTION #11722

Question 7764

A VFD (Variable Frequency Drive) is set to operate a 3-phase induction motor at 30 Hz instead of 50 Hz. To maintain constant motor flux (V/Hz ratio), the output voltage should be set to:

$380\,\text{V}$
$228\,\text{V}$✔️
$190\,\text{V}$
$480\,\text{V}$

Correct Answer Logic:

The V/Hz ratio for constant flux: $\dfrac{V}{f} = \dfrac{380\,\text{V}}{50\,\text{Hz}} = 7.6\,\text{V/Hz}$. At 30 Hz: $V = 7.6 \times 30 = \mathbf{228\,\text{V}}$. This constant V/f control maintains constant air-gap flux, preserving motor torque capability below rated speed. Above rated frequency, voltage is held constant (field-weakening region).

Maths QUESTION #2825

Question 7767

Solve the simultaneous equations: $2x + 3y = 12$ and $x - y = 1$.

x=2 y=3
x=3 y=2✔️
x=4 y=1
x=1 y=4

Correct Answer Logic:

From $x - y = 1$: $x = y + 1$. Substitute into first equation: $2(y+1) + 3y = 12 \Rightarrow 2y + 2 + 3y = 12 \Rightarrow 5y = 10 \Rightarrow y = 2$. Then $x = 3$.
