Why would a scientist most likely chose to perform a simulation instead of a lab experiment or field observation? O The lab experiment might be dangerous or too difficult to do.
O Simulations rely on mathematical analysis and have one correct answer.
Field observations are less accurate than computer simulations.
Simulations are more accurate than lab work.

because they want 2 and yea

1. desertification

2. captive breeding

3. black rhinoceros

4. renewable resources

explanation:

mark brainliest!

that scientist would be robert hooke

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
