The water in the hand pump is hot in winter because water comes out from inside and absorbs heat from the surroundings; option [D]. When water travels through pipes underground, it absorbs heat from the relatively warmer Earth. As a result, when it is pumped out, it feels warmer compared to the colder atmospheric temperature. This phenomenon occurs due to the natural tendency of water to reach thermal equilibrium with its surroundings, where it absorbs heat from the warmer environment.
This process is not influenced by our body’s temperature or the temperature inside the Earth being higher than the atmosphere. Friction generated during pumping might slightly heat the water, but it’s not the primary reason for the water being hot. Instead, the predominant factor is the water’s absorption of heat from the surrounding environment.
Therefore, the correct option is [D]. Water absorbs heat from the surroundings, particularly the warmer Earth, as it travels through underground pipes, resulting in it feeling warmer when pumped out during winter.

Leg bone in the human body is [C] solid. The leg bones, including the femur, tibia, and fibula, are composed of dense cortical bone tissue, which is solid and compact. This solid structure provides strength, support, and protection to the lower limbs, allowing them to withstand the forces exerted during weight-bearing activities like walking, running, and jumping.
Unlike some bones, such as the long bones of birds, which can be hollow to reduce weight, human leg bones are solid to better withstand the mechanical stresses and strains encountered during locomotion. Additionally, the porous nature of bone tissue, known as trabecular or cancellous bone, is present within the interior of the bone to provide flexibility and absorb shock.
Overall, the solid composition of leg bones ensures their durability and functionality, enabling efficient movement and weight-bearing while minimizing the risk of fractures and injuries.

The smallest bone of the human body is [C] Stapes. Found in the middle ear, the stapes, also known as the stirrup bone, measures only a few millimeters in length. Despite its small size, it plays a crucial role in the transmission of sound vibrations from the outer ear to the inner ear.
Attached to the tympanic membrane (eardrum) on one end and the oval window of the cochlea on the other, the stapes acts as a bridge that transfers sound waves across the middle ear.
As sound waves travel through the ear canal and vibrate the eardrum, these vibrations are amplified and transmitted through the auditory ossicles, including the stapes, to the fluid-filled cochlea, where they are converted into electrical signals for processing by the auditory nerve.
The remarkable sensitivity and precise movement of the stapes contribute to the intricate process of hearing in the human body.

There are [A] 12 pairs of ribs in the human body. Ribs are long, curved bones that form the rib cage, a protective structure surrounding the chest cavity. The rib cage plays a crucial role in protecting vital organs such as the heart, lungs, and major blood vessels.
Of the 12 pairs of ribs, the first seven pairs are known as true ribs because they connect directly to the sternum (breastbone) via costal cartilage. The next three pairs are called false ribs, with the eighth, ninth, and tenth ribs attaching indirectly to the sternum or to the cartilage of the seventh rib. The last two pairs, the eleventh and twelfth ribs, are floating ribs because they do not attach to the sternum at all, only to the vertebrae.
The ribs provide structural support to the thoracic cavity and contribute to the mechanics of breathing by expanding and contracting with the movement of the diaphragm and intercostal muscles during respiration.

The approximate number of bones in newborn babies is [C] 300. Newborn infants have more bones than adults because many bones are not yet fully formed or fused together. Over time, some of these bones fuse, reducing the total count. At birth, the human skeleton includes various cartilaginous structures and bones in different stages of development, contributing to the higher count. As the baby grows, several bones, particularly those in the skull and pelvis, gradually fuse together to form larger, single bones. By adulthood, the total number of bones decreases to around 206 due to this fusion process. Understanding the differences in bone development between newborns and adults is essential in fields such as pediatrics, orthopedics, and anatomy, as it influences medical diagnosis, treatment approaches, and developmental milestones.
