  1. Trial and error

  4. Conditioning

  5. Imprinting

Show answer
Correct Option: B
Explanation:

The internal need that leads an individual or organism to act is known as motivation. A motive prompts and individual to act in a certain way, or at least develop an inclination for specific behavior. Motivations refers to the internal and external factors that stimulate the desire to do or learn.

Identify the correct term for the statement, 'mating between groups do not produce fertile offspring'.

biology habits and habitats of some important animals behavioural science ethology animal behaviour

  1. Geographical isolation

  2. Mechanical isolation

  3. Temporal isolation

  4. Hybrid sterility

  5. Behavioral isolation

Show answer
Correct Option: D
Explanation:

Presence of populations of a species in distant localities preventing the gene flow between them leads to geographical isolation. Incompatible differences in reproductive structures leading to prevention of cross fertilization refers to as mechanical isolation. Different periods of attainment of sexual maturity leads to temporal isolation. Incompatible premating behaviour leading to no attraction between groups for mating is termed as behavioural isolation. Abnormal distribution to the gametes of whole chromosomes, chromosome segments, or combinations of genes leading to infertile hybrid is one of the post zygotic isolation.

Therefore, the correct answer is option D.

  1. Territorial

  2. Learned

  3. Innate

  4. Stereotyped

  5. Conditioned

Show answer
Correct Option: A
Explanation:

Territorial behavior is the method by which an animal or a group of animals protects its territory from incursions by others of its species. It is not affected by the environmental changes.

Learned behaviors are acquired changes in the behaviors, during one's lifetime. 
Innate behaviors are inherited and performed correctly the first time an organism is exposed to a certain stimulus.
Stereotypic behavior is an abnormal behavior frequently seen in laboratory primates. It is considered an indication of poor psychological well-being 
All the above-mentioned behaviors except for territorial is affected by environmental changes.
So, the correct answer is option A.

Identify the unusual behavioural pattern of animals.

biology habits and habitats of some important animals behavioural science ethology animal behaviour

  1. Bluffing

  2. Instinct

  3. Mimicry

  4. All of the above

Show answer
Correct Option: A
Explanation:

Instinct and mimicry are the behaviours which are shown by the animals. Instinct is the ability to judge an event and give response accordingly. Mimicry is performed in order to protect them. Bluffing is an unusual behaviour which may be seen due to fear. This may be used as a form of communication for protection against the predator.

Thus, the correct answer is option A.
