  4. Imitation

Show answer
Correct Option: A
Explanation:

  1. A person's fear of anything comes under the behavior of instinct.
  2. Conditioning is the particular or predictive response towards particular stimuli.
  3. Imprinting is a type of behavior that is genetically present and is considered to be the response to a particular stimuli.
  4. Imitation is a behavior in which an organism tries to copy others.
So, the correct option is 'Instinct'.

  1. Praise

  2. Smoking

  3. Spanking

  4. Both B and C

Show answer
Correct Option: A
Explanation:

Positive reinforcement for a conditioned behaviour can be provided by adding an appetitive stimulus at the end of correct behaviour. It can be in the form of a praise.

So, the correct option is 'Praise'.

Learning is associated with

  1. Conditioning

  2. Imitation

  3. Instinct

  4. Both A and B

Show answer
Correct Option: D
Explanation:
  • Conditioning is a behavioral process whereby a response becomes more frequent or more predictable in a given environment as a result of reinforcement, with reinforcement typically being a stimulus or reward for the desired response.
  • Imitation is an advanced behavior whereby an individual observes and replicates another's behavior. 
  • Both Imitation and conditioning are part of the learning process in organisms. Hence, option D is correct.

Which of the following organism was used as an experimental model for the investigation of conditioning behaviour?

  1. Ducklings

  2. Dog

  3. Dolphin

  4. Bee

Show answer
Correct Option: B
Explanation:

Dogs were used as an experimental model for the investigation of conditioning behavior and the experiments were done by Russian physiologist Ivan Pavlov in which he showed that the dogs could be conditioned unconsciously with neutral, unrelated event with feeding.

So, the correct option is 'Dog'.

Imitation is

  1. Involuntary response

  2. Voluntary response

  3. Stimulus

  4. None of the above

Show answer
Correct Option: B
Explanation:

A) An involuntary response is not under conscious control. It generally constitutes the reflexes.

B) A voluntary response is controlled by our consciousness.
Imitation is controlled by our consciousness as when we imitate; we observe, learn and then reciprocate. 
C) Stimulus is the input to one's body, it can be either external or internal.
So, the correct option is 'Voluntary response'.

  1. Imitation

  2. Conditioning

  3. Instinct

  4. None of the above

Show answer
Correct Option: D
Explanation:

A) Imitation is a behavior in which an organism observes, learns and reciprocates other organisms.

B) Conditioning is a behavior which can be predicted with the altering of the consequences due to the previous observation of the organism.
C) Instinct is a behavior in response to any provided stimulus.
D) Ants follow marching due to the scent left behind by followed ants. This scent is due to a hormone called pheromone.
So, the correct option is 'None of the above'.

Human behaviour is more complex because 

biology animal behaviour ethology coordination in human beings- chemical control endocrine system in humans

  1. They can not control their behaviour and aware of themselves.

  2. They can control their behaviour and aware of themselves.

  3. They have well developed nervous system.

  4. None of the above.

Show answer
Correct Option: B
Explanation:
There are various biochemical reactions which take place in response to the stimulus which is received. The type of response given by the humans as a part of the behavior is based on these biochemical reactions. There are the different type of biochemical reactions occurring in the different organs which together contribute to the response. The humans can control the behavior. They are aware of themselves and know what is the response given at the stimulus. This makes the behavior complex because there are many aspects which are associated with the behavior. 
Thus, the correct answer is option B. 

Organisms reproducing throughout the year are called ______ breeders e.g., _____, and those who show recurring sexual activity are called _______ breeders e.g., _________.

biology animal behaviour ethology coordination in human beings- chemical control endocrine system in humans

  1. Continuous, sparrow, seasonal, hen

  2. Seasonal, lizard, continuous, hen

  3. Continuous, man, seasonal, tiger

  4. Seasonal, hen, continuous, tiger

Show answer
Correct Option: C
Explanation:
Sexuality in Animals Just like plants, animals also exhibit variation in attaining sexual maturity. Some animals remain reproductively active throughout their reproductive phase; such animals are called continuous breeders, e.g., human. On the other hand, there are some animals, which become reproductively active only during favourable seasons in their reproductive phase; such animals are called seasonal breeders, e.g., dog, birds, frog, lizard, tiger, etc.
So, the correct answer is 'Continuous, man, seasonal, tiger'.

Which one of the following is not true of singing in male birds?

biology animal behaviour ethology coordination in human beings- chemical control endocrine system in humans

It is seen in birds, mammals. A niche of an organism is a functional role it plays into an ecosystem. Territory is a sociographical area that is defended by group of animals of a particular species from other animals of different species for purposes like mating, nesting, roosting, feeding. 

Thus, the correct answer is 'Lek.'
