The excretory system is a collection of organs tasked with removing excess nitrogen and other toxins from the body. Several parts of the body such as sweat glands (excretion of sweat), liver (detoxifies and breaks down chemicals, poisons and other toxins that enter the body), lungs (disposal of carbon dioxide through exhalation) and kidneys (excretion of waste through urinary system) are involved in this process. The spleen is the organ that is responsible for both the storage and purification of red blood cells.

Photosynthesis in plants converts radiant energy from the sun into chemical energy in the form of glucose (sugar) using electrons and protons from water. Plants take in water, carbon dioxide, and sunlight and turn them into glucose and oxygen. Water (6H₂O) + Carbon Dioxide (6CO₂) + Sunlight (Radiant Energy) = Glucose (C₆H₁₂O₆) + Oxygen (6O₂).

Bonsai is the Japanese art of growing dwarf trees. By contrast with other plant cultivation practices, bonsai is not intended for production of food or for medicine. Instead, bonsai practice focuses on longterm cultivation and shaping of one or more small trees growing in a container. Bonsai uses cultivation techniques like pruning, root reduction, potting, defoliation, and grafting to produce small trees that mimic the shape and style of mature, full-size trees.

Bacillus Calmette–Guérin (BCG) vaccine is a vaccine primarily used against tuberculosis. The vaccine was originally developed from Mycobacterium bovis which is commonly found in cows. It is on the World Health Organization’s List of Essential Medicines, the most effective and safe medicines needed in a health system,

Along with duck-billed platypus, the four species are among the five species of monotremes, the only mammals that lay eggs instead of giving birth. Echidna, also known as the Spiny Anteater, is a primitive oviparous (egg-laying) mammal that lives in Australia and New Guinea. Echidnas lay a single egg in a pouch on the female’s belly.
