Testis and ovary function as a primary sex organ as well as endocrine gland

Ovaries are located in thoracic cavity of females

Ovary produces ovum, 2 groups of steroid hormones (estrogen and progesterone)

Ovary is composed of ovarian follicles and stromal tissue

The fibrous cords attached to the flaps of the bicuspid and tricuspid valves are chordae tendinae.

The opening of inferior vena cava is guarded by Eustachian valve.

The right atrio-ventricular opening is guarded by the mitral valve.

Impulses received from carotid sinuses decreases heart rate whereas impulses received from vena cava increases heart rate.

A person of 'O' blood group has anti 'A and anti 'B' antibodies in his blood plasma.

A person of 'B' blood group can't donate blood to a person of 'A blood group.

Blood group is designated on the basis of the presence of antibodies in the blood plasma.

A preson of AB blood group is universal recipient.

Glycolysis operates as long as it is supplied with NAD that can pick up hydrogen atoms

Glycolysis occurs in cytosol

Enzymes of TCA cycle are present in mitochondrial matrix

Oxidative phosphorylation takes place in outer mitochondrial membrane

All the elements present in a sample of earth's crust are also present in a sample of living tissue

Relative abundance of carbon and hydrogen with respect to other elements is higher in any living organisms than in earth's crust

Living organisms have more nitrogen and oxygen per unit mass than in animate object (e.g. earth crust)

Living organisms have more Ca, Mg, Na in them than in animate object

All

Only III and IV

Only IV

None of the above

The competitive inhibitor does not affect the rate of breakdown of the enzyme-substrate complex

The presence of the competitive inhibitor decreases the Km of the enzyme for the substrate

A competitive inhibitor reacts reversibly with the enzyme to form an enzyme-inhibitor complex

In competitive inhibition, the inhibitor molecule is not chemically changed by the enzyme

Viroids lack a protein coat

Viruses are obligate parasites

Infective constituent in viruses is the protein coat

Prions consist of abnormally folded proteins
