In the transverse section of a dicot stem, the xylem is located more interiorly (towards the center) than the phloem, which is found on the outer side of the vascular bundles. Dicot stems have vascular bundles arranged in a ring around the periphery of the stem. Within each vascular bundle, the xylem is located towards the center (interior) of the bundle, and the phloem is located towards the outside (exterior).

Kwashiorkor is a severe form of malnutrition caused primarily by a deficiency of protein in the diet. It typically occurs in children who have been weaned from breast milk to a diet that is high in carbohydrates (such as maize, rice, or cassava) but lacks sufficient protein to support growth and repair. The hallmark symptom is oedema (swelling due to fluid retention), which often results in a distended or "pot-belly" appearance.

Sundews (Drosera) and bladderworts (Utricularia) are carnivorous plants that supplement their nutrition by trapping and digesting insects/small organisms, getting essential nutrients like nitrogen from prey, while still being autotrophic (photosynthesizing) for energy, making their nutrition partially heterotrophic/carnivorous to overcome nutrient-poor soil.

During a water bath, which is usually 4–10 minutes, the solution of the mixture and Benedict's solution should progress in the colors of blue (with no reducing sugar present), orange, yellow, green, red, and then brick red precipitate or brown (with high reducing sugar present). A color change would signify the presence of a reducing sugar.

The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.

The systemic circulation is the part of the vascular system that carries blood from the left ventricle to organs and tissues of the body. Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide.

The normal function of sebaceous glands is to produce and secrete sebum, a group of complex oils including triglycerides and fatty acid breakdown products, wax esters, squalene, cholesterol esters and cholesterol. Sebum lubricates the skin to protect against friction and makes it more impervious to moisture.

Each urinary tubule begins in the CORTEX as a cup-like structure known as the Bowman's capsule.

nastic movements are non-directional responses to stimuli (e.g. temperature, humidity, light irradiance) that occur more rapidly than tropisms and are usually associated with plants.

In biochemistry, chemosynthesis is the biological conversion of one or more carbon molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic (e.g. hydrogen gas, hydrogen sulfide) or methane as a source of energy, rather than sunlight, as in photosynthesis.

- The stomach is very acidic, with a pH of 3.5 or below, so it can break down food.

Ameoba and paramecium are examples of Protozoa. An Ameoba gets rid of excess water that enters its cell by using a Contractile Vacoule.
