which statement about adaptations is correct as it pertains to the scientific theory of evolution?
a
adaptations, which are beneficial genetic traits, are critical to the survival of a species by providing alternative ways to adjust to a changing environment and prevent extinction.

b
adaptations, processes in which a single surviving organism chooses to change its traits, allows a species to redevelop variability and to increase in numbers.

c
adaptations, processes in which an organism physically changes its environment, provide a way for a species to decrease its numbers to prevent competition.

d
adaptations, which are learned behaviors, allow organisms to learn how to survive in any environment and predict environmental changes in order to prevent extinction of the species.

scientists collect data regarding earth's surface temperature over the last 900,000 years using direct and indirect methods. if they construct a graph of this data, which statement best describes the graph?
a
the graph would start low, and then curve upward significantly to show a rapid rise in average temperatures.

b
the graph would have a fairly straight line with a sharp curve upward to show recent rising temperatures.

c
the graph would show stable temperatures followed by a sharp curve down as temperatures cooled.

d
the graph would have both highs and lows to show the periods of warm and cool temperatures.
