The cell is the basic structural and functional unit of life.

The cell is the basic unit of life.

The boiling point of pure water at sea level is 100°C.

The boiling point of water at sea level is 100°C.

Neutrons have no charge; they are neutral particles found in the nucleus of an atom.

A proton has a positive charge of +1.

Regular physical activity increases basal metabolic rate (BMR) and total daily energy expenditure (TDEE) due to increased muscle mass and metabolic activity.

The jelly-like substance inside the cell is called cytoplasm.

Nervous tissue is characterized by its ability to transmit impulses.

Mass = Volume × Density = 50 mL × 1 g/mL = 50g.

The mass of an electron is much smaller than that of a proton.

The third energy level can hold a maximum of 18 electrons.

Percentage of salt = (5g / (5g + 95g)) * 100 = 5%.

The atomic nucleus is primarily composed of protons and neutrons.

ATP (Adenosine triphosphate) is the primary energy source that muscles use for contraction during motion.

The phosphagen system is the primary energy system used during high-intensity, short-duration activities, providing immediate energy through stored ATP and creatine phosphate.

Epithelial tissue primarily functions to protect and cover surfaces.

Ribosomes are responsible for protein synthesis in the cell.

The cerebellum is primarily responsible for coordinating voluntary movements and maintaining balance.

The cochlea converts sound waves into electrical signals that can be interpreted by the brain.

The primary function of the kidneys is to filter blood and remove waste products.

The vestibular system is responsible for maintaining balance and spatial orientation by detecting changes in head position.

Cellular respiration is the primary mechanism by which the body converts food energy into ATP, the usable form of energy for cells.

The auditory ossicles amplify sound waves and transmit them from the eardrum to the inner ear.

Muscle contraction primarily relies on ATP, which provides the energy needed for muscle fibers to contract.

The process of a solid changing directly into a gas is called sublimation.

Insulin decreases blood sugar levels by facilitating the uptake of glucose into cells.

Proprioceptors are sensory receptors that provide information about body position and movement, crucial for coordination.

An atom is the smallest unit of an element that retains its chemical properties.

Solids have a definite shape and volume due to closely packed particles.
