Answer:

The correct answer will be option-how nature would act without manipulation.

Explanation:

A scientific experiment is designed in a way that it can be categorized into two groups:  

1.  experimental samples-in which the variable to be studied is present and other variables can be manipulated.

2. Control group: samples in which the variable to be tested is not present and thus contains only independent variables. The control group provides the data which shows how nature acts when no manipulation is done to the variable which acts as a reference group to the experimental group.

Therefore, the selected option is the correct answer.

telo118 [61]

Answer:

there asking  

How the climatic zones of the planet influence rhythmic and seasonal changes

Explanation:

The Earth is tilted 23.5 degrees on its axis, which affects the distribution of the sun’s energy across the surface of the planet. As the Earth orbits the sun every 365 ¼ days, the axis is always pointing in the same direction into space, with the North Pole toward Polaris, the North Star. Around June 22, the northern hemisphere is angled towards the sun, and receives the most direct radiation and the most energy. This is the start of astronomical summer in the northern hemisphere and winter in the southern hemisphere.
