Answer: machinery and equipment developed from the application of scientific knowledge.
Carbon dioxide is a colorless and non-flammable gas at normal temperature and pressure. Although much less abundant than nitrogen and oxygen in Earth's atmosphere, carbon dioxide is an important constituent of our planet's air. A molecule of carbon dioxide (CO2) is made up of one carbon atom and two oxygen atoms. Carbon dioxide is an acidic colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas.
Answer:
Lipids
If i were to guess, without any answer choices, I would say that we get out energy from carbohydrates, and we store energy in lipids, so Lipids (being long chains) might have the most energy.
