Answers
Answer:
❤️soil : ❤️ Soil is composed of both biotic—living and once-living things, like plants and insects—and abiotic materials—nonliving factors, like minerals, water, and air. Soil contains air, water, and minerals as well as plant and animal matter, both living and dead. These soil components fall into two categories.
❤️air : ❤️ Composition of air
Composition of airNitrogen — 78 percent. Oxygen — 21 percent. Argon — 0.93 percent. Carbon dioxide — 0.04 percent.
❤️brass ❤️: The composition of brass, generally 66% copper and 34% zinc, makes it a favorable substitute for copper based jewelry as it exhibits greater resistance to corrosion.
❤️milk ❤️ : In general, the gross composition of cow's milk in the U.S. is 87.7% water, 4.9% lactose (carbohydrate), 3.4% fat, 3.3% protein, and 0.7% minerals (referred to as ash). Milk composition varies depending on the species (cow, goat, sheep), breed (Holstein, Jersey), the animal's feed, and the stage of lactation.
