The correct statements are-
Erosion occurs even when the mountains are forming. Erosion is the movement of sediments from the broken rocks through the agents like gravity, wind, water and others. It is a constant process occurring even while the mountains are forming. It is affected by gravity.
When new mountains or plateaus form, the cycle starts over. Weathering is the breakdown of rocks by the weathering agents. These sediments move due to the process of erosion. A new sediment may be dropped nearby or in a new place by the process of deposition. Weathering, erosion and deposition occur together as a cycle and have almost leveled the land surface.
Weathering, erosion and deposition have almost leveled earth’s surface. These three processes occur as a cycle and have almost leveled the land surface.
Answer:
The correct answer is e it depends primarily on positive feedback.
Explanation:
The term homeostasis deals with maintenance a constant or steady physiological state in our body.Homeostasis helps to maintain the level of all bio-active compounds such as hormones,vitamins,metabolites,antibodies,minerals within their normal cellular range.
it is because disturbance or hamperence of normal cellular level of bio-active compounds cause various physiological abnormalities in our body for example increase blood glucose level results in diabetes.
The term homeostasis depends on both positive feedback(to stimulate the production of bio-active compounds) and negative feedback(to inhibit the formation of bioactive compounds) according to our body"s need.
Answer:
The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. Changes that allow an organism to better adapt to its environment will help it survive and have more offspring.
Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from a wide variety of scientific disciplines, including paleontology, geology, genetics and developmental biology.
