Question 3856

AKrait

BKing cobra

CChain viper

DSaw scaled viper

Show answer

B. King cobraExplanation: The King Cobra (Ophiophagus hannah) is the world’s longest venomous snake and the only snake species that builds a nest to lay its eggs. The female collects leaves, twigs, and debris to construct a mound-like nest, usually near dense vegetation or fallen logs. She lays about 20–40 eggs in the nest and guards them aggressively until they hatch, showing remarkable parental care — a rare behavior among reptiles. Once the eggs are about to hatch, the female leaves the nest to avoid eating her own offspring, as King Cobras are carnivorous and feed mainly on other snakes.

AVitamin A

BVitamin B

CVitamin C

DVitamin D

Show answer

B. Vitamin BExplanation: Cow’s milk is a nutritionally rich food containing proteins, fats, carbohydrates, minerals, and vitamins. It is particularly rich in B-group vitamins, especially Vitamin B₂ (Riboflavin) and Vitamin B₁₂ (Cobalamin). These vitamins play crucial roles in maintaining healthy skin, eyesight, and the nervous system, as well as aiding in the formation of red blood cells. Note: While milk provides moderate amounts of Vitamin A and D, the natural content of Vitamin D is low, and milk is often fortified with Vitamin D to enhance its nutritional value.

Question 3854

Aherbs are used to relieve pain

Bneedles are inserted into particular parts of the body to relieve pain

Csurgery is done to relieve pain

Dnone of these

Show answer

B. needles are inserted into particular parts of the body to relieve painExplanation: Acupuncture is an ancient form of traditional Chinese medicine that involves the insertion of very thin needles through the skin at specific points, called acupoints. It is based on the concept of balancing the flow of life energy (Qi or Chi) through pathways in the body known as meridians. When these energy flows are blocked or imbalanced, it can cause illness or pain. By stimulating specific acupoints, acupuncture is believed to restore the normal energy flow and help the body heal itself. It is commonly used to treat: Chronic pain (e.g., back, neck, and joint pain) Migraines and headaches Arthritis and muscle stiffness Stress and anxiety Scientific View: Modern research suggests that acupuncture may stimulate nerves, muscles, and connective tissue, boosting the body’s natural painkillers (endorphins).

Question 3853

SA-node of mammalian heart is known as :

AAutoregulator

BPace-maker

CTime controller

DBeat regulator

Show answer

B. Pace-makerExplanation: The Sinoatrial (SA) node is a specialized group of modified cardiac muscle fibers located in the right atrium of the heart, near the opening of the superior vena cava. It generates electrical impulses (action potentials) that initiate each heartbeat. Therefore, it is known as the natural pacemaker of the heart. The impulses from the SA node spread across the atria, causing them to contract, and are then transmitted to the Atrioventricular (AV) node, Bundle of His, and Purkinje fibers to coordinate ventricular contraction. Normal rate of SA node firing: ~70–75 impulses per minute (in a healthy adult at rest). In case of SA node failure: Artificial pacemakers are implanted to maintain normal rhythm.
