Q1. Which of the following is not a part of coxal bone?
Answer : Option A
Explaination / Solution:
The coxal bone (hip bone, pelvic bone) is a large, flattened, irregularly shaped bone, constricted in the center and expanded above and below.
It consists of three parts, the ilium, ischium, and pubis, which are distinct from each other in the young subject, but are fused in the adult.
Q2. Human protein α-1-antitrypsin is used to treat
Answer : Option D
Explaination / Solution:
Transgenic organisms produce useful biological products. Augmentation therapy is the use of alpha-1 antitrypsin protein (AAT) from the blood plasma of healthy human donors to augment (increase) the alpha-1 levels circulating in the blood and lungs of Alphas diagnosed with emphysema.
Human protein α-1-antitrypsin is used to treat emphysema is also obtained from transgenic animal.
Q3. Oxidation number of −1/2 is assigned to oxygen atom in
Answer : Option B
Explaination / Solution:
In the superoxide ion, O2−, the oxygen has an oxidation number of −1/2. The stability of metal superoxides depends on the size and the electropositive character of the metal. The larger the metal and the more electropositive it is, the greater the stability of its superoxide.
Q4. The period between entry of pathogen into the body and appearance of first symptom is called
Answer : Option A
Explaination / Solution:
The period between entry of pathogen into the body and appearance of first symptom is called incubation period. It varies from a few days up to 7 years as in case of AIDS.
Q5. When will the domestic income be greater than the national income?
Answer : Option B
Explaination / Solution:
No Explaination.
Q6. The dielectric constant K of an insulator can be
Answer : Option D
Explaination / Solution:
Dielectric constant of air is 1. All dielectrics generally have a value of the dielectric constant greater than 1.where is the force between two charged particles in a medium of dielectric constant K and F is the force between the two charges when placed in air.The force between two charges is greatest in air or vacuum and it decreases when any medium is placed between the charges. K cannot have negative, fractional or zero values.
Q7. Intermolecular forces of thermoplastic polymers are
Answer : Option B
Explaination / Solution:
Intermolecular forces are intermediate between elastomers and fibres.
Q8. Which of the following is an amphoteric oxide?
Answer : Option A
Explaination / Solution:
Higher oxidation state oxides are acidic while lower oxidation state oxides are basic. Intermediate oxidation state oxides are amphroteric.
Q9. Which of the following statements regarding ordinal utility is true?
Answer : Option A
Explaination / Solution:
No Explaination.
Q10. Angular momentum of a body is defined as the product of
Answer : Option A
Explaination / Solution:
if r is perpendicular to p (in case of circular motion)
L = mvr
