The correct answer is [D] Dermatology. Dermatology is the branch of medicine and science that focuses on the study, diagnosis, and treatment of diseases and conditions related to the skin, hair, nails, and mucous membranes. Dermatologists undergo extensive training to understand the structure, function, and disorders of the skin, including its physiology and anatomy. They examine the skin’s layers, appendages, and associated structures to diagnose various conditions such as acne, eczema, psoriasis, skin cancer, and more.
Dermatologists also investigate the biochemical processes underlying skin health and disease, collaborating with biochemists and researchers to develop new treatments and therapies. By integrating knowledge from physiology, anatomy, biochemistry, and clinical practice, dermatology plays a crucial role in maintaining skin health and treating dermatological disorders, ensuring the overall well-being of individuals.
As a result of complete oxidation of glucose, [C] 38 molecules of ATP are formed. This occurs through the process of cellular respiration, which includes glycolysis, the Krebs cycle (also known as the citric acid cycle), and oxidative phosphorylation.

As a result of complete oxidation of glucose, [C] 38 molecules of ATP are formed. This occurs through the process of cellular respiration, which includes glycolysis, the Krebs cycle (also known as the citric acid cycle), and oxidative phosphorylation. In glycolysis, glucose is converted into two molecules of pyruvate, generating a net of 2 ATP molecules. The pyruvate then enters the mitochondria, where it undergoes the Krebs cycle, producing ATP, NADH, and FADH₂. Finally, in oxidative phosphorylation, the high-energy electrons carried by NADH and FADH₂ are used to generate ATP through the electron transport chain. Overall, the complete oxidation of one molecule of glucose produces a total of 38 molecules of ATP, making it a highly efficient process for energy production in cells.
In humans, the amount of O₂ in the air exhaled during respiration is [B] 16%. During respiration, oxygen is taken in from the air during inhalation and used by the body's cells for metabolic processes. As a result, the concentration of oxygen in exhaled air is lower than inhaled air. Exhaled air typRead more
In humans, the amount of O₂ in the air exhaled during respiration is [B] 16%. During respiration, oxygen is taken in from the air during inhalation and used by the body’s cells for metabolic processes. As a result, the concentration of oxygen in exhaled air is lower than inhaled air. Exhaled air typically contains approximately 16% oxygen, compared to the roughly 21% oxygen content of ambient air. The difference reflects the uptake of oxygen by the body’s tissues for cellular respiration. In addition to oxygen, exhaled air contains higher concentrations of carbon dioxide and water vapor, which are byproducts of cellular metabolism. This exchange of gases occurs in the lungs during the process of respiration, facilitating the exchange of oxygen and carbon dioxide between the bloodstream and the external environment.

The process of respiration takes place in [A] Mitochondria. Mitochondria are specialized organelles found in eukaryotic cells responsible for cellular respiration. During respiration, mitochondria use oxygen to break down glucose molecules through a series of biochemical reactions, ultimately generating ATP (adenosine triphosphate), the cell’s primary energy source. This process occurs in the inner mitochondrial membrane and involves the electron transport chain and oxidative phosphorylation.
Unlike chloroplasts, which are involved in photosynthesis, and ribosomes, which are responsible for protein synthesis, mitochondria play a crucial role in aerobic respiration, enabling cells to produce energy efficiently. Lysosomes, on the other hand, are involved in intracellular digestion and the recycling of cellular waste, while ribosomes function in protein synthesis. However, it is within the mitochondria that the complex biochemical processes of respiration occur, highlighting their significance in cellular metabolism and energy production.
The control center of reflex actions is [C] In the vertebral cord. Reflex actions are rapid and involuntary responses to stimuli, such as withdrawing your hand from a hot surface. These responses are coordinated by neural circuits located within the spinal cord, bypassing higher brain centers like tRead more
The control center of reflex actions is [C] In the vertebral cord. Reflex actions are rapid and involuntary responses to stimuli, such as withdrawing your hand from a hot surface. These responses are coordinated by neural circuits located within the spinal cord, bypassing higher brain centers like the cerebrum. When a sensory neuron detects a stimulus, it sends a signal directly to motor neurons in the spinal cord, which then trigger the appropriate muscle response. This allows reflex actions to occur quickly, without needing input or processing from the brain. While the brain, including the cerebrum and cerebellum, plays a role in more complex voluntary movements and coordination, reflex actions are primarily controlled at the level of the vertebral cord, where specialized reflex arcs are responsible for their execution.
