Biology problems
- 1. The Mode of nutrition in which particulate food is devoured is
Options- A. holozoic
- B. holophytic
- C. saprophytic
- D. Parasitic Discuss
Correct Answer: holozoic
Explanation:
The feeding mechanism is of several types. If it is entirely plant-like (photosynthesis),it is called holophytic. It is entirely (holo) animal-like (zoic), that is devouring already existing food, it is called holozoic.
- 2. Infection of salivary glands by a virus leads to
Options- A. tetanus
- B. mumps
- C. pyorrhoea
- D. ulcers Discuss
Correct Answer: mumps
Explanation:
Mumps: This is a swelling caused by inflammation of parotid glands placed in front of our ear region. The Inflammation is caused by a virus.
- 3. The insects do not have blood pigments because
Options- A. there is no blood
- B. tissues have pigments
- C. blood does not have a respiratory function
- D. pigments are elsewhere Discuss
Correct Answer: blood does not have a respiratory function
Explanation:
The blood of some invertebrate animals like the earthworm is red due to haemoglobin pigment, but the pigment is dissolved in the plasma. In vertebrates the same pigment is found in the red corpuscles and not in the plasma.
- 4. Activation of the receptors by stimuli is called
Options- A. Adaptation
- B. Perception
- C. Habituation
- D. Sensation Also asked in: AIEEE, Bank Exams, Analyst, Bank Clerk
Correct Answer: Sensation
Explanation:
Sensation is the activation of the receptors by stimuli.
- 5. Type 1 diabetes is more common than type 2 ?
Options- A. TRUE
- B. FALSE Also asked in: AIEEE, Bank Exams, CAT, Analyst, Bank Clerk, Bank PO
- If you have type 1 diabetes your body does not release insulin.
- If you have type 2 diabetes your body does not use insulin properly.
Correct Answer: FALSE
Explanation:
Type 2 diabetes is the most common form of diabetes.
- 6. What carries Blood back to the Heart?
Options- A. Veins
- B. Arteries
- C. Both A & B
- D. None Also asked in: Bank Exams, AIEEE, Bank PO, Bank Clerk, Analyst
Correct Answer: Veins
Explanation:
Veins carries Blood back from the body parts to the Heart.
We know that The circulatory system of our body is a loop. The Heart is the pump, the arteries and their smaller branches (arterioles) carry oxygen rich blood all through your body and the veins and their smaller branches (venules) carry oxygen depleted blood and waste products back.
- 7. Which of the following does not occur during Mitosis?
Options- A. spindle formation
- B. condensation of the chromosomes
- C. breakdown of the nuclear membrane
- D. replication of the DNA Also asked in: AIEEE, Analyst
Correct Answer: replication of the DNA
Explanation:
Replication of the DNA does not occur during Mitosis.
- 8. Unlike Mitosis, Meiosis results in the formation of
Options- A. 2N daughter cells
- B. Haploid cells
- C. body cells
- D. Diploid cells Also asked in: AIEEE, Bank Exams, Analyst, Bank Clerk, Bank PO
Correct Answer: Haploid cells
Explanation:
Unlike Mitosis, Meiosis results in the formation of 4 Genetically different cells.
Meiosis results in the formation of 4 Haploid daughter cells from one Diploid parent cell.
- 9. How many Nephrons are in each kidney?
Options- A. 10,000
- B. 1,00,000
- C. 1,000,000
- D. 1000 Also asked in: AIEEE, Bank Exams, CAT, Analyst, Bank Clerk
Correct Answer: 1,000,000
Explanation:
There are about 1,000,000 nephrons in each human kidney.
Nephron, functional unit of the kidney, the structure that actually produces urine in the process of removing waste and excess substances from the blood.
- 10. Which event occurs during interphase?
Options- A. Centrioles appear
- B. Spindle fibers begin to form
- C. The cell grows
- D. Centromeres divide Also asked in: AIEEE, Bank Exams, Analyst, Bank Clerk, Bank PO
Correct Answer: The cell grows
Explanation:
The cell carries out the metabolic processes and it grows during interphase.
The cell cycle has three phases that must occur before mitosis, or cell division happens. These three phases are collectively known as interphase. They are G1, S, and G2.
