Answer:
by developing more efficient methods of mining coal
Explanation:
Coal is a combustible black or brownish black sedimentary rock. Coal is produced by the dead plant matter. It is a fossil fuel that is used for generating electricity in the thermal power plants, used as cooking fuel, and fuel in automobiles. The burning of the coal results in the liberation of carbon dioxide, sulphur dioxide and carbon monoxide gases in the environment. These gases are responsible for causing the air pollution.
Developing more efficient methods of mining coal is not a conservation tactic related to coal consumption because the more the efficient mining will promote the excavation of the coal, which will further contribute to its extensive consumption and air pollution.
line A is the answer because enzymes act as catalyst for chemicals reactions which means that they help speed up the production of products from a chemical reaction
Answer:
The correct answer would be C. The tortoises provided evidence that different species have adaptations suited to their particular environments.
Darwin observed that how different environment on different island lead to the development of different species as a result of adaptations and natural selection.
For example, tortoise inhabiting well-watered islands which used to have short and cropped vegetation had developed a dome-shaped shell.
In contrast, the tortoise inhabiting the arid islands had developed saddle-shaped shells. It is because they needed to stretch their necks in order to reach branches of cactus and other vegetation available in the area.
Consequently, they developed long necks and high peak to the front edges of their shells. It made it possible for them to stretch their heads vertically.
Answer: a tiny muscle connected to each hair follicle and the skin. When it contracts it causes the hair to stand erect, and a "goosebump" forms on the skin.
