1 / 15

What can be inferred if facial hair develops in boys aged 13?

Less intake of iodine in the diet

Over-secretion of growth hormone

Abnormal secretion of insulin

Timely secretion of testosterone

2 / 15

Receptors → Spinal cord → Sensory neuron → Motor neuron → Muscle

Receptors → Motor neuron → Spinal cord → Sensory neuron → Muscle

3 / 15

What can be inferred if swollen necks are observed in people living in the hills?

Timely secretion of testosterone

Less intake of iodine in the diet

Abnormal secretion of insulin

Over-secretion of growth hormone

4 / 15

Which of the following statements about the transmission of nerve impulses is incorrect?

Nerve impulse travels from the dendritic end towards the axonal end.

At the dendritic end electrical impulses bring about the release of some chemicals which generate an electrical impulse at the axonal end of another neuron.

The chemicals released from the axonal end of one neuron cross the synapse and generate a similar electrical impulse in a  dendrite of another neuron.

A neuron transmits electrical impulses not only to another neuron but also to muscle and gland cells.

5 / 15

Which plant hormone promotes cell enlargement and cell differentiation and promotes fruit growth?

Abscisic acid

Gibberellins

Cytokinin

Auxins

6 / 15

A deficiency of iodine will cause this disease in the body:

Goitre

Marasmus

Night Blindness

Beri Beri

7 / 15

The electrical impulse travels in a neuron from

Dendrite → cell body → axon → axonal end

Cell body → dendrite → axon → axonal end

Dendrite → axon → axonal end → cell body

Axonal end → axon → cell body → dendrite

8 / 15

Person X suffers from a condition that affects the normal functioning of the pituitary gland.

Which of the following is most likely a direct effect of person X’s condition?

Inability to regulate blood sugar

Insufficient growth of the body

Irregular heartbeat

Insufficiency of iodine
