A carbon footprint is a measure of the amount of carbon human activities, like using energy, release into the atmosphere. Which activity would help decrease the greatest carbon-releasing activity in US homes? limiting time in hot showers wearing layers of clothing turning off lights when leaving a room unplugging electronics when not in use
Answer: unplugging electronics when not in use
Explanation:
Carbon footprint is the measure of the amount of carbon liberated into the atmosphere due to human oriented activities like burning of fossil fuels, deforestation, liberation of toxic gases including carbon monoxide and carbon dioxide into the atmosphere by the factors and automobile vehicles. To stop the carbon releasing activity in US homes one must unplug the electronic not in use because electronics consume a lot of electrical energy every day this electrical energy comes from thermal power plants which typically use coal to harness energy the combustion of the coal liberates carbon dioxide and carbon monoxide in the environment so creating pollution and increases the carbon footprint. Little will be the usage of electricity little will be the burning of coal and it will decrease the carbon footprint.

1- how can prokaryotes be used by humans/professionals?
2- how can eukaryotes be used by humans/professionals?
3- how can digestive system be used by professionals?
Answer: 1 Fermentation processes, such as brewing, baking, and cheese and butter manufacturing. Chemical manufacturing, such as the production of ethanol, acetone, organic acids, enzymes, and perfumes. Pharmaceuticals, such as the manufacture of antibiotics, vaccines, and steroids. Energy, in the form of biogas (methane)
2 Despite the fact that we have gobs of prokaryotic cells living inside and on us, humans are still categorically eukaryotic organisms. This means that all human cells—including those found in the brain, the heart, the muscles, and so on—are also eukaryotic.
