Questions Related to zoology

Fill in the blank with correct option.
________ gave cognitive dissonance theory.

zoology neural control and coordination parts of the brain brain and its parts brain

  1. Festinger

  2. Binet

  3. Heider

  4. None of the above

Show answer
Correct Option: A

The limbic system is formed by

zoology neural control and coordination parts of the brain brain and its parts brain

  1. The hypothalamus ,epithalamus ,amygdala and hippocampus

  2. Hypothalamus ,amygdala and hippocampus

  3. Corpora quadrigemina and hippocampus

  4. Midbrain and hindbrain

Show answer
Correct Option: A
Explanation:

the limbic system is made up of the amygdala, hippocampus, thalamus, hypothalamus, basal ganglia, and cingulate gyrus.  All the components of the limbic system work together to regulate some of the brain's most important processes.

Anaesthetics reduce pain by blocking nerve conduction due to

zoology neural control and coordination parts of the brain brain and its parts brain

  1. Blocking neurotransmitter receptors

  2. Blocking N$a^+$ channels

  3. Blocking $K^+$ channels

  4. All the above

Show answer
Correct Option: B

Feeling of anger, pain and pleasure are experienced through

zoology neural control and coordination parts of the brain brain and its parts brain

  1. Frontal lobe

  2. Limbic system

  3. Parietal lobe

  4. Reticular system

Show answer
Correct Option: B

Which of the following brain structure is not considered to be part of limbic system?

zoology neural control and coordination parts of the brain brain and its parts brain

  1.  Amygdala

  2. Hippocampus

  3. Corpora quadrigemina

  4. Septal nuclei

Show answer
Correct Option: C
Explanation:
  • The limbic system is the portion of the brain that deals with three key functions: emotions, memories, and arousal (or stimulation).
  • The components of the limbic system include Amygdala, Hippocampus, Septal nuclei, thalamus, hypothalamus, basal ganglia.
  • The posterior surface of the adult midbrain is characterized by four elevations collectively called the corpora quadrigemina. It is not a part of the limbic system.
  • Hence the brain structure is not considered to be part of the limbic is Corpora quadrigemina.
  • So, the correct answer is 'Corpora quadrigemina'.

Somatic gene therapy causes ___________.

  1. Changes in sperm

  2. Changes in progeny

  3. Changes in body cell

  4. Changes in ovum

Show answer
Correct Option: A

SCID is caused by defective gene coding for enzyme ______________.

  1. Adenosine deaminase

  2. Adenosine transaminase

  3. Adenosine transferase

  4. Guanosine transaminaseGuanosine deaminase

Show answer
Correct Option: A
Explanation:

Adenosine deaminase deficiency SCID, commonly called ADA SCID, is a very rare genetic disorder. It is caused by a mutation in the gene that encodes a protein called adenosine deaminase (ADA). 

Which vector is used to replace defective gene in gene therapy?

  1. Cosmid

  2. Ri plasmid

  3. Ti plasmid

  4. Adenovirus

Show answer
Correct Option: D

  1. Both the Assertion and the Reason are true and the Reason is a correct explanation of the Assertion.

  2. Both the Assertion and Reason are true but the Reason is not a correct explanation of the Assertion.

  3. The Assertion is true but the Reason is false.

  4. Both the Assertion and Reason are false.

  5. The Assertion is false but Reason is true.

Show answer
Correct Option: B
Explanation:

An antiviral drug is used to treat genital herpes outbreaks stay symptom-free longer. These drugs can also reduce the severity and duration of symptoms when they do flare up. Drug therapy is not a cure, but it can make living with the condition easier. Because of lack of research about the Herpes virus action mechanism, there is no cure for Herpes but it is inhibited by acyclovir. It is one of the most common sexually transmitted infections. 

Which of these is used as vector for gene therapy in SCID and gene cloning in higher organisms?

  1. Retrovirus

  2. Enterovirus

  3. Arbovirus

  4. Rotavirus

  5. Parvovirus
