Imprinting

Operant conditioning

Classical conditioning

Habituation

4. The main function of cerebellum is

Remembering

5. To induce labour _______ hormone is given:

Growth

Antidiuretic

Thyroid

Oxytocin

6. Hormone sometimes given by injection as an emergency treatment in cardiac arrest, anaphylactic shock and acute asthma attack is:

7. During the transmission of nerve impulse through a nerve fibre, the potential on the inner side of the plasma membrane has which type of electric charge?

First positive, then negative and continue to be negative

First negative, then positive and continue to be positive

First positive, then negative and again back to positive

First negative, then positive and again back to negative

8. The region where the impulse moves from one neurons to another is:

Synapse

Axon-Halloick

Soma

Node of Ranvier

9. Cytokinins are originally obtained from:

Coconut milk

Rice milk

Dare milk

Almond milk

10. Automatic, involuntary responses which occur either due to internal or external stimuli are:

Synapses

Resting Membrane Potential

Reflex Action

Action Potential

11. Pheromone is

Always protein

Used for animal communication

Messenger RNA

A product of endocrine gland

12. __________ is learning that occurs during a sensitive or critical period in early life irreversible for the length of the period.

Imprinting

Trial and error learning

Habituation

Operant conditioning

13. One of the naturally occurring cytokinin is:

Creatin

Zeatin

Kinetin

Reatin

14. Which statement is true for nerve conduction?

Rise in stimulus induces permeability to Na+ is long lived.

During resting stage axonal membrane is less permeable for K+ and more permeable for Na+.

During transmission of impulse, Na+ outfiux continuously.

Concentration gradient generated when active transportation of ions occurs by Na- K pump.

Chemoreceptors

Mechanoreceptors

Painreceptors

Thermoreceptors

18. You want to train your puppy to wait at the curb until you tell him to cross the road. Your friend advises you to give your dog a treat every time he does as you ask. Your friend is advising that you train the dog using

GABA

Acetylcholine

Norepinephrine

Dopamine
