Biology problems
- 1. Increasing the Alveolar ventilation rate will
Options- A. Increase the rate of carbon dioxide diffusion from the blood to the alveoli
- B. Decrease the partial pressure of oxygen in the alveoli
- C. Increase the partial pressure of carbon dioxide in the alveoli
- D. Have no effect on either partial pressure or diffusion rate of gases Also asked in: AIEEE, Analyst
Correct Answer: Increase the rate of carbon dioxide diffusion from the blood to the alveoli
Explanation:
Increasing the Alveolar ventilation rate will increase the rate of carbon dioxide diffusion from the blood to the alveoli.
- 2. The vitamin D deficiency disease in adults is known as
Options- A. Hypovitaminosis D
- B. Avitaminosis
- C. Scorbutus
- D. Petechiae Also asked in: AIEEE, Bank Exams, Analyst, Bank Clerk
Correct Answer: Hypovitaminosis D
Explanation:
Vitamin D also known as Sunshine vitamin is produced in the body when our skin is exposed to sunlight. Its deficiency leads to a disease in which bone tissue doesn't properly mineralize leading to soft bones. The vitamin D deficiency disease in adults is known as Hypovitaminosis D.
- 3. Which of the following is a characteristic of all angiosperms?
Options- A. double internal fertilization
- B. ovules that are not contained within ovaries
- C. complete reliance on wind as the pollinating agent
- D. free-living gametophytes Also asked in: AIEEE, Analyst
Correct Answer: double internal fertilization
Explanation:
The flowering plants, also known as angiosperms, Angiospermae or Magnoliophyta, are the most diverse group of land plants. These are also seed producing plants like gymnosperms. In Angiosperms seeds are in flowers.
- 4. Select the correct statement about active and passive immunity.
Options- A. A vaccination is an example of the introduction of passive immunity into the body
- B. Active and passive humoral immunity are both mechanisms of adaptive immunity that useantibodies
- C. Immunological memory is established by passive immunization
- D. The antibodies utilized in active immunity are acquired from another organism Also asked in: AIEEE, Analyst
Correct Answer: Active and passive humoral immunity are both mechanisms of adaptive immunity that useantibodies
- 5. Visceral pain usually starts in which of the following?
Options- A. Kidneys
- B. Abdomen
- C. Rectum
- D. Esophagus Also asked in: AIEEE, Bank Exams, Analyst, Bank Clerk
Correct Answer: Abdomen
Explanation:
Visceral pain is a poorly localized, dull, or diffuse pain. It usually arises from the abdominal organs.
- 6. Dynamic equilibrium receptors are found in the
Options- A. Vestibule
- B. Maculae
- C. Semicircular Canals
- D. Cupula Also asked in: AIEEE, Analyst
Correct Answer: Semicircular Canals
Explanation:
Dynamic equilibrium receptors are found in the Semicircular Canals. It monitors angular or rotational movements of the head when the body ismoving, such as a figure skater?s spinning, but maintaining balance.
- 7. Which blood group is called universal donor?
Options- A. AB-
- B. O-
- C. AB+
- D. O+ Also asked in: AIEEE, Bank Exams, Analyst, Bank Clerk, Bank PO
Correct Answer: O-
Explanation:
O- blood group is called universal donor. AB+ is called as universal acceptor.
- 8. A dissecting aortic aneurysm occurs when
Options- A. The inner layers of the aorta become separated
- B. The aorta ruptures, resulting in profound bleeding
- C. All layers of the aorta suddenly contract
- D. None of the above Also asked in: AIEEE, Bank Exams, CAT, Analyst, Bank Clerk, Bank PO
Correct Answer: The inner layers of the aorta become separated
Explanation:
A dissecting aortic aneurysm occurs when the inner layers of the aorta become separated.
- 9. Slow oxidative muscle fibers are best suited for
Options- A. Hitting football
- B. Heavy workout in the gym
- C. Running a marathon
- D. None of the above Also asked in: AIEEE, Bank Exams, Analyst, Bank Clerk, Bank PO
Correct Answer: Running a marathon
Explanation:
The three types of muscle fibers are slow oxidative (SO), fast oxidative (FO) and fast glycolytic (FG). Slow oxidative fibers use aerobic metabolism to produce low power contractions over long periods and are slow to fatigue.
