Correct Answer: modified forelimbs

Solution : The correct option is modified forelimbs.

The wings of birds are modified forelimbs. This modification is a result of evolution, where over time, the forelimbs of certain dinosaurs, the ancestors of birds, evolved into wings to facilitate flight. This evolutionary process is an

Correct Answer: $\frac{4+\sqrt{2}}{2}$

Solution : Given: $\frac{1}{\operatorname{cosec} \theta+1}+\frac{1}{\operatorname{cosec} \theta-1}=2 \sec \theta$
⇒ $\frac{\operatorname{cosec} \theta - 1 + \operatorname{cosec} \theta + 1}{\operatorname{cosec}^2 \theta - 1} = 2 \sec \theta$
⇒ $\frac{2 \operatorname{cosec} \theta}{\operatorname{cosec}^2 \theta - 1} = 2 \sec \theta$
⇒ $\operatorname{cosec} \theta = \sec \theta (\operatorname{cosec}^2 \theta - 1)$
We

Correct Answer: NTSAP

Solution : Given:
ROBOT is written as BOTOR and BRING is written as INGRB.

Shuffle the position of the letters of the words ROBOT and BRING to get the required codes.

So, ROBOT is written as BOTOR.

So, BRING is written as INGRB.
Similarly, follow the same

Correct Answer: 2

Solution : According to the dice rule, if two or three positions of the same dice are given with two common faces but in different orientations, then out of those two common faces the faces that are not common are opposite to each other.
While considering Figures

Correct Answer: $20\sqrt3$ units

Solution :
$\triangle ABC$ is right-angled at B.
$\sin\theta$ = $\frac{\text{Perpendicular}}{\text{Hypotenuse}}$
⇒ $\sin 60°$ = $\frac{AB}{AC}$
⇒ $\frac{\sqrt{3}}{2} = \frac{30}{AC}$
⇒ AC = $\frac{60}{\sqrt{3}}$
$\therefore$ AC = $20\sqrt{3}$ units
Hence, the correct answer is $20\sqrt{3}$ units.

Correct Answer: U

Solution : Given:
(I) P is sitting third to the right of U. S is sitting second to the right of P.

(II) R is an immediate neighbour of both T and U. Q is sitting to the immediate left of S.

So, U is the immediate

Correct Answer: Resolving power

Solution : The correct option is resolving power.

The ability of an optical system, such as a telescope or microscope, to recognise two objects far off as distinct and separate objects is referred to as resolving power. It assesses the system's capacity to deliver precise, in-depth
