  3. Instinct

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
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.

  2. Dog

  3. Dolphin

  4. Bee

B Correct answer
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'.

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

  3. They have well developed nervous system.

  4. None of the above.
Reveal answer Fill a bubble to check yourself
B Correct answer
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.

Reveal answer Fill a bubble to check yourself
C Correct answer
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.
