Answer:They can tell by what type of fossils there are
Explanation:Identification of the minerals in a rock is the first thing you do. You can do it in some highly granular rocks with nothing more than a magnifying hand lens. This is called hand specimen examination. This a qualitative analysis.
The sun gives off _solar___energy, which enters the atmosphere. Plants absorb some of the energy and perform photosynthesis to convert it into_chemical__energy in the form of sugars. Plants and the animals that eat them then turn that energy into a different form of _chemical___
energy, in the form of ATP. When plants and animals use the energy, it becomes _heat_ energy.
The energy producing process for life starts with the use of solar energy by plants in photosynthesis. Green plants takes up solar energy from the sun and uses it to manufacture sugar and oxygen gas in the presence of carbon dioxide and water. The sugar stores chemical energy.
When the food produced by plant is eaten, during cellular respiration, the ATP formed from break down of the food is used to liberate heat energy. The bond between the second phosphate element is broken down and heat energy is released from the stored chemical energy.
This gives off carbon dioxide and water as the by product.

Answer:
the answer for this is B.
Answer:
The height to which to tomato plants grow
Explanation:
In an experiment, the dependent variable is the variable that the experimenter measures. It is the variable that responds to changes made to the independent/manipulable variable.
According to this question, students investigate how soil pH affects the height of tomato plants. The different pH each plant receives is the independent variable while the HEIGHT OF THE PLANTS that responds to the soil pH or that is measured by the students is the DEPENDENT VARIABLE.
Dependent would be amount of colds.
Controlled would be amount of vitamin C taken.
Independent could be the fact that vitamin C will be taken daily.
