Answer:
1. primary cause of human-created carbon emissions = burning fossil fuels
2. destroys natural carbon sinks leading to more carbon dioxide in the air = deforestation
3. emits methane from decomposing matter = waste disposal in landfills
Explanation:
1. "Fossil fuels" are <em>nonrenewable resources</em> that are considered essential for the operation of many factories and industries. <em>Burning them accounts for most of the carbon emissions on Earth</em>, and this leads to<em> "global warming."</em>
2. "Forests" are considered "carbon sinks" because they have a role of <u><em>absorbing the carbon dioxide in the atmosphere</em></u>. Cutting down the trees (deforestation) makes forests barren. It then leads to more carbon dioxide in the air.
3.<em> Waste disposals in landfills contribute to the amount of methane that is released into the atmosphere.</em> Methane is considered a <em><u>potent greenhouse gas</u></em> that affects people's health.
Answer:
The correct answer is photosphere.
Explanation:
Visible light comes from the layer known as the photosphere.
The Sun's photosphere is the layer that emits visible light. The Sun's atmosphere has seven layers: The core, or the Sun's interior. The radiative zone. The convective zone. The photosphere or the visible surface. The Chromosphere. And the corona, the outermost layer.
Cells depend on the body environment to live and function. Homeostasis<span> keeps the body environment under control which keeps the conditions right for the cells to live and function. Not having the right body conditions can result in certain processes and proteins won't function properly.</span>
