Answer : 4. "Insect"
Explanation :

Fragrant flowers attract pollinators like bees, butterflies, and birds with their pleasant scent. These pollinators visit the flowers to feed on nectar or collect pollen. During their visits, they unintentionally transfer pollen from one flower to another, facilitating pollination. This process enables the plant to reproduce and produce seeds. Different plants rely on specific pollinators, ensuring their reproductive success and genetic diversity within the ecosystem.

Answer : 3. "Iron"
Explanation :

Iron is the metal found in blood. It is an essential mineral that plays a key role in transporting oxygen from the lungs to the rest of the body and carrying carbon dioxide back to the lungs to be exhaled. Iron is a crucial component of hemoglobin, a protein in red blood cells that binds to oxygen and gives blood its red color. Without sufficient iron, the body cannot produce enough healthy red blood cells, leading to iron-deficiency anemia, a common nutritional disorder.

Answer : 2. "Heart"
Explanation :

A pacemaker is a medical device used to regulate the heartbeat in individuals with abnormal heart rhythms (arrhythmias). It is often implanted in the chest to help control the heart's rhythm and treat conditions like bradycardia (slow heart rate) or other rhythm disorders. Pacemakers are typically prescribed by cardiologists, specialized doctors who diagnose and treat heart-related conditions. The decision to implant a pacemaker is made by a healthcare provider based on the patient's specific medical condition and needs.

Answer : 2. "colon"
Explanation :

In humans, the tailbone, also known as the coccyx, is a small triangular bone located at the base of the spine. It is made up of three to five fused (joined together) vertebrae and is the remnant of a tail that our evolutionary ancestors used for balance and communication. The coccyx is not attached to the colon; rather, it is a part of the vertebral column and provides support for the pelvic organs.
