Consider the following:
Statement-I: Both BeSO$_4$ and MgSO$_4$ are readily soluble in water.
Statement-II: Among the nitrates of alkaline earth metals, only Be(NO$_3$)$_2$ on strong heating gives its oxide, NO$_2$, and O$_2$.
The correct answer is
When a wire is connected in the left gap of a metre bridge, the balancing point is at \( 40 \) cm from the left end of the bridge wire. If the wire in the left gap is stretched so that its length is doubled and again connected in the same gap, then the balancing point from the left end of the bridge wire is:
The solution of the differential equation \( x^2 (y + 1) \frac{dy}{dx} + y^2 (x + 1) = 0 \), when \( y(1) = 2 \), is
A bag contains 4 red and 6 blue balls. Two balls are drawn one after the other without replacement. What is the probability that the second ball drawn is red, given that the first ball drawn was blue?
If \( a \pm bi \) and \( b \pm ai \) are roots of \( x^4 - 10x^3 + 50x^2 - 130x + 169 = 0 \), then find the value of \( \frac{a}{b} + \frac{b}{a} \).

A rectangular slab consists of two cubes of copper and brass of equal sides having thermal conductivities in the ratio \(4 : 1\). If the free face of brass is at \(0^\circ \text{C}\) and that of copper is at \(100^\circ \text{C}\), then the temperature of their interface is
If A(1,0), B(0,-2), C(2,-1) are three fixed points, then the equation of the locus of a point P such that area of \( \triangle \text{PAB} \) is equal to area of \( \triangle \text{PAC} \) is

A circle touches the line \(2x + y - 10 = 0\) at (3, 4) and passes through the point (1, -2). Then a point that lies on the circle is
If \( \alpha, \beta, \gamma \) are the roots of the equation \( x^3 + ax^2 + bx + c = 0 \), then \( (\alpha + \beta - 2\gamma)(\beta + \gamma - 2\alpha)(\gamma + \alpha - 2\beta) = \)

Choose the correct statements among the following

I. Joseph Priestley (1770): Showed that plants have the ability to take CO2 from the atmosphere and release O2.
II. Jan Ingenhousz (1779): Release of CO2 by plants was possible only at night and only by the non-green parts of plants.
III. Julius Von Sachs (1884): Green parts in plants produce glucose which is stored as starch.
IV. C. Van Niel (1931): Photosynthesis is essentially a light dependent reaction in which hydrogen from an oxidizable compound reduces CO2 to form carbohydrates.
