Which is true about scientific theories? (2 points)

They are proposed by scientists who wish to investigate a new topic.

They are the result of a single experiment.

They are only based on the most recent evidence.

They are the results of many experiments over a long period of time.

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.
