(of a river or road) follow a winding course
No it do not but it uses gravity and falls fast So. The surface do not affect how fast objects fall. Hope this helps:)
There is only 1 negative choice here, so you can solve by common sense.
C. They reproduce slower than unicellular organisms.
This is true because, for example, think of humans. We take 9 months to reproduce uses multiple stages of meiosis. Unicellular organisms on the other hand, such as bacteria, are asexual and use binary fission to reproduce, which happens very quickly, but creates less diversity.
An example would be Climate change
Answer:
D. Time and pressure changes dead plant material to peat.
Explanation:
There are four steps in the production of coal: peat, lignite, bituminous and anthracite.
Peat: in this stage dead plants are oxidized to water and carbon dioxide and buried under sediments. The partial decomposition of plant matter due to the absence of oxygen is called peat. There is no factor of time and pressure that changes dead plant material to peat.
Lignite: Peat is subjected to heat, pressure, and time to form lignite.
Bituminous: More pressure in lignite removes all the traces of plant matter and form “soft coal”, bituminous coal.
Anthracite: It is the last stage, in which hard coal forms with the combined pressure and high temperature.
Hence, the correct answer is "D. Time and pressure changes dead plant material to peat."
