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.

Fill in the table below by writing the complementary strand of DNA that would be formed by each template strand

BlackZzzverrR [31]

Answer:

DNA strand = complementary strand

GCAAG = CGTTC

TTACG = AATGC

GATAC = CTATG

CGGAT = GCCTA

DNA strand = mRNA strand

CGATT = GCUAA

GCTTA = CGAAU

GCATC = CGUAG

TTCAT = AAGUA

Explanation: A complementary strand is not the same in base composition and sequence with the template strand. In DNA, anywhere adenine is found in the template strand, thymine is found in the complementary strand and anywhere cytosine is found in the template strand, guanine is found in the complementary strand. But in RNA, anywhere adenine occurs in the DNA template strand, uracil occurs in the mRNA strand, wherever thymine occurs in the DNA template strand, adenine occurs in the mRNA strand and wherever guanine occurs in the DNA template strand, cytosine occurs in the mRNA strand.

Summarily, in DNA adenine pairs with thymine while cytosine pairs with guanine while in mRNA, adenine pairs with uracil, while cytosine pairs with guanine.

Compare and contrast hurricanes, tornadoes, and blizzards

horsena [70]

Answer:

Compare:

They are all natural disasters that cause a lot of damage.

Contrast:

Hurricanes are storms that cause high waves and can get into citys and towns and cause a lot of water damage.

Tornadoes are tunnels of wind that cause wind damage.

Blizzards are storms with strong winds and snow that can cause water, and wind damage!

Hope this helped :)
