List of practice Questions

Consider the following: Statement I: CCl₄ does not undergo hydrolysis. But SiCl₄ undergoes hydrolysis.
Statement II: Thermal and chemical stability of GeX₄ is more than GeX₂.

A body of mass $5~\text{kg}$ starts from the origin with an initial velocity $\vec{v}_0 = (30\hat{i} + 40\hat{j})~\text{m/s}$.
If a constant force $\vec{F} = -(i + 5j)~\text{N}$ acts on the body, then the time in which the y-component of its velocity becomes zero is

If a gas of volume $400~\text{cc$ at an initial pressure $P$ is suddenly compressed to $100~\text{cc}$, then its final pressure is (The ratio of specific heats $\gamma = 1.5$)}

If the distance travelled by a freely falling body in the last but one second of its motion is 5 m, then the last second is:

Three plants, Mustard, Calotropis, and Guava, are collected. There are 30 nodes in Mustard, 30 nodes in Calotropis, 25 nodes in Guava are present. Find the number of leaves put together in all three plants?

Loss of chlorophyll leading to yellowing in leaves is called:

Choose the incorrect statements:

I. Electrons from NADH produced in the mitochondrial matrix are oxidized by complex II
II. Ubiquinones oxidised to ubiquinol by receiving reducing equivalents from complex I
III. Ubiquinol oxidized to ubiquinone by transfer of electrons to complex III

In which crosses both phenotypic and genotypic F$_2$ ratios are 1:2:1?

I) Red $\times$ White snapdragon (incomplete dominance)
II) Tall $\times$ Dwarf garden pea
III) Dotted $\times$ Spotted seed coat lentil
IV) Homozygous $\times$ Heterozygous

Assertion (A): Genetic maps are extensively used as a starting point in the Human genome sequencing project.
Reason (R): Frequency of recombination between gene pairs on the same chromosome as the measure of distance between genes and mapped their position is called gene mapping.
