The magnification of a standard ocular lens on a light microscope is typically 10X. The ocular lens, also known as the eyepiece, is the lens closest to the observer's eye. It magnifies the image produced by the objective lens, which is the lens closer to the specimen being observed. Together, the ocular lens and the objective lens determine the total magnification of the microscope. The standard ocular lens provides a magnification of 10X, meaning it magnifies the image by a factor of 10 compared to the naked eye.

Passive transport refers to the movement of molecules across a biological membrane without the expenditure of cellular energy. This process occurs down the concentration gradient, meaning molecules move from areas of higher concentration to areas of lower concentration until equilibrium is reached. It includes simple diffusion, where small, non-polar molecules like oxygen and carbon dioxide can pass directly through the lipid bilayer of the membrane, as well as facilitated diffusion, where larger or polar molecules move across the membrane with the help of transport proteins, such as channel proteins or carrier proteins. Overall, passive transport is essential for maintaining the balance of molecules within cells and between different cellular compartments.

Water is the major component of blood plasma, making up approximately 90-92% of its composition by volume. Blood plasma is the liquid portion of blood, composed mostly of water along with dissolved solutes, such as ions, nutrients, gases, hormones, and waste products. Water in blood plasma serves as the solvent for carrying nutrients, hormones, and other molecules throughout the body, facilitates gas exchange in the lungs and tissues, helps regulate body temperature, and maintains blood volume and pressure. The remaining components of blood plasma, including ions (such as sodium, potassium, and calcium), proteins (such as albumin, globulins, and fibrinogen), and other solutes, contribute to various physiological functions in the body.

Glycolysis is the first step in the process of cellular respiration, which is the metabolic pathway by which cells generate ATP (adenosine triphosphate), the energy currency of the cell. Glycolysis occurs in the cytoplasm and involves the breakdown of glucose, a six-carbon sugar, into two molecules of pyruvate, a three-carbon compound. During glycolysis, glucose is oxidized and ATP is produced through substrate-level phosphorylation. Glycolysis is anaerobic, meaning it does not require oxygen, and is common to both aerobic and anaerobic respiration pathways.
