An astronomer wants to visualize the relative distances between planets in our solar system. a biologist wants to examine the branching of blood vessels within the body. a chemist wants to see the angles between bonds in a molecule. a geologist wants to view the layers of the earth from core to crust.

what is the best method that all of these different scientists could use to perform their investigations?

a. perform a field study
b. create a controlled laboratory experiment
c. build a model
d. all of these

C. build a model

Explanation:

Build a model is the correct method so as to perform the investigation as the model can be used to simulate the astronomical, biological, chemical and geological natural processes occurring in nature. The model can give an idea about the cause of a natural phenomena. It can be used to mention the distance between the two separate bodies, morphological features of body of living organisms, the angles between the bonds of the molecules, it can also be used to describe the layers of the earth from core to crust.

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.

gans

explanation:

vestigial organs (like your appendix) are organs that no longer serve a purpose.
