b. placer mining
c. subsurface mining
d. none of the above
Answer;
-Surface mining
Explanation;
-Mining involves the extraction of valuable minerals or other geological materials from the earth, commonly from an orebody, lode, vein, seam, reef or placer deposit. Despite having a large range of advantages economically, mining impacts the environment negatively because minerals are contained within the Earth. Earth must be removed in order to extract the minerals. When the minerals are close to the surface, the earth is removed, causing destruction to the shape of the land and the flora and fauna living in that area.
-Among different types of mining, surface mining is one of the method that greatly impacts the environment. It destroys all plant life in the area the mine occupies. Plants living in the area where the surface mine is to be located are removed. After the surface mine is no longer productive, plants may eventually return to the area, but typically some human efforts at reclamation are required to restore the environment to some level of productivity.

Explanation:
plants in the desert experience a large amount of transpiration
b.
plants in the rainforest release a large amount of water to the atmosphere
c.
plants in the rainforest experience a small amount of transpiration
d.
the fewer plants an area has, the smaller the amount of transpiration there is
Answer:
The correct answer is option b. "plants in the rainforest release a large amount of water to the atmosphere".
Explanation:
It is considered that rainforests are partly self-watering because plants itself promote precipitation by releasing a large amount of water to the atmosphere. This process known as transpiration helps to create a thick cloud, which helps to create an atmosphere humid and warm. Plants' transpiration is one reason why rainforests have more precipitation than deserts.

Answer:
Helicase enzyme melts the DNA double helix and forms single stranded DNA strands.
Explanation:
Helicases are ATP dependent enzymes that bind to the DNA at the origin of replication. Helicases move along the DNA and use the energy of ATP to breakdown the hydrogen bonds between complementary base pairs that otherwise hold the two DNA strands together.
Breaking of hydrogen bonds releases two DNA strands from each other. These single-stranded DNA molecules then serve as the template for DNA replication.
Answer:
Gypsum and limestone.
Explanation:
Mining of valuable stones such as gypsum and limestone occur in my location. These valuable stones are used in the formation of beautiful tiles and in painting materials. Due to extraction of these valuable stones, erosion of the land occur as well as air pollution increases by the use of machines for extracting these minerals so it caused adverse affect on the environment so this mining has to be limited in order to both save the environment and get benefits from these minerals
Answer:
(Answers may vary.)I live in Utah. Copper is mined in my state. Bingham Canyon Mine is the copper mine in Utah. Copper mining has played a vital role in the economic and social development of my state.Copper is used for variety of purposes. Most electrical appliances use copper. Moreover, water pipes, weather stripping, and wires use copper. Copper is used for making automobiles, ships, airplanes, and various other materials that we use on a daily basis.Copper in Utah is mined in open pit mines. They are severely impacting the environment. The hazardous pollutants, such as lead and arsenic, emitted during the mining process are affecting the fish and wildlife habitats in the nearby areas. Apart from impacting wildlife, the mines are polluting the groundwater in our state.Copper mining in Utah has positively affected economic development in the state. However, it has negatively affected wildlife and groundwater.
