A cockroach of mass \( m \) is moving with a velocity \( v \) in the anticlockwise direction on the rim of a disc of radius \( R \). The moment of inertia of the disc about the axis is \( I \) and it is rotating in a clockwise direction with an angular velocity \( \omega \). If the cockroach stops moving, the angular velocity of the disc will be:

Three point masses \(m_1, m_2, m_3\) are located at the vertices of an equilateral triangle of side 'a'. The moment of inertia of the system about an axis along the altitude of the triangle passing through \(m_1\) is:

In a hydroelectric power station, the water is flowing at \(2 \, {ms}^{-1}\) in the river which is \(100 \, {m}\) wide and \(5 \, {m}\) deep. The maximum power output from the river is:

A body of mass \(2 \, {kg}\) is placed on a smooth horizontal surface. Two forces \(F_1 = 20 \, {N}\) and \(F_2 = 10\sqrt{3} \, {N}\) are acting on the body in the directions making angles of \(30^\circ\) and \(60^\circ\) to the surface. The reaction of the surface on the body is:

A block of mass \(m\) is placed in equilibrium on a moving horizontal plank. The maximum horizontal acceleration of the plank for \(\mu = 0.2\) is (Acceleration due to gravity = \(10 \, {ms}^{-2}\)).

Match the following:

Choose the correct statements among the following:
I. Bird flu is a fungal disease affecting poultry.
II. Propolis is bee glue used to seal the cracks in the honeycomb.
III. The world's livestock population in India and China together is more than 70%, but their contribution to world's farm produce is 25%.
IV. Inactivated whole agent vaccine acts against typhoid.
Which combination of statements is correct?

Match the following:

Consider the following statements about prokaryotic and eukaryotic cells:
Statement I: Some prokaryotes evolved into mitochondria and plastids in the bodies of ancestral eukaryotes.
Statement II: The endomembrane system of eukaryotes might have evolved by infolding of the plasma membrane.
Which of the following is correct?

Match the following:

Identify correct statements regarding the Human Genome Project:
Statements :
I. The method of DNA sequencing was developed by Jeffreys.
II. Identification of genes that express as RNA is referred to as Expressed Sequence Annotation.
III. About 1.4 million locations where single base DNA differences occur in humans.
IV. Y-chromosome has 231 genes.

Assertion: The male ants are developed by parthenogenesis from unfertilized eggs.
Reason: The sex of offspring depends on the type of sperm that fertilizes the ovum, which is not relevant since male ants develop through haploid parthenogenesis, which does not involve fertilization.

Identify the incorrect statements regarding blood groups:
Statements:
(1) The mother with Rh\(^{-}\) blood group develops passive immunity on administering IgM antibodies.
(2) Isoagglutinogens are sugar polymers bound to fatty acids on the RBC membrane.
(3) The alleles for Rh factor are located on three different loci on chromosome pair 9.
(4) The expression of ABO blood types in man is by three alleles of a single gene.

Trichomoniasis is caused by:

Human chorionic gonadotropic hormone resembles this hormone in its function:

Arrange the following in increasing order of their pK\(_b\) values.
