Answer:

Wind, solar, geothermal, biomass, and hydropower also have environmental impacts, some of which are significant. Fossil fuels do substantially more harm than renewable energy sources by most measures. By understanding the potential environmental issues associated with each renewable energy source, we can takes steps to effectively avoid or minimize these impacts. Biomass power plants generate electricity from biomass that can be sustainably produced and utilized in the United States for energy and fuel, focusing on agricultural residues, waste materials, and forest biomass. In other regions enhanced geothermal systems (or hot dry rock geothermal), which involve drilling into the earth's surface to reach deeper geothermal resources, can allow broader access to geothermal energy.

Future of hydroelectric power in the United States will likely involve increased capacity at current dams and new run-of-the-river projects. Large-scale hydroelectric dams continue to be built in many parts of the world (including China and Brazil) There are environmental impacts at both types of plants. While actual impacts of large-scale operations have not been observed, a range of potential impacts can be projected.

Answer:

All energy sources have some impact on our environment. Fossil fuels—coal, oil, and natural gas—do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions.

What are glaciers? A glacier is a huge mass of ice that moves slowly over land.
tigry1 [53]

Answer:

What do they look like?

Glaciers look like solid blocks of ice.

What climate do they exist in?

Regions that have high snowfall in winter and cool temperatures in summer.

Where can you find them?

Most of the world's glacial ice is found in Antarctica and Greenland, but glaciers are found on nearly every continent, even Africa.

What do you think we can learn from glaciers?

Glaciers preserve bits of atmosphere from thousands of years ago in these tiny air bubbles, or, deeper within the core, trapped within the ice itself. This is one way scientists know that there have been several Ice Ages. Scientists are also finding that glaciers reveal clues about global warming.

(The last question is unclear to me, so I'm going to take a guess as to what you meant)

Why is sea ice so important?

Arctic sea ice keeps the polar regions cool and helps moderate global climate.

I hope this helps!! :3

what cellular mechanisms allow human body cells to maintain these concentrations ?
sweet [91]
Answer:


Active transport: movement against a gradient To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the proper concentrations of ions and molecules in living cells.

What function do chloroplasts perform
Scilla [17]

Answer:

Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant. Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis.
