The study of microorganisms is called microbiology
Answer:
No.
Explanation:
No, hand-crank flashlight would not be a good energy system for the rescue workers because the light turns on by applying muscle force on the hand-crank flashlight and after that, the device convert muscle force into electric energy and the light turns on and we know that the rescue worker have a tough job which requires both hands so this hand-crank flashlight is not useful to him.
Answer:
Planting trees, CARBON CYCLE, and cooking with gas do not add Carbon dioxide to the atmosphere.
Explanation:
The atmosphere naturally breathes or decomposes carbon dioxide rocks, whereas forest fire takes place and volcanoes erupt.
The atmosphere is naturally decomposed. Human activities like fossil fuel and forest burning, and cement production, also add carbon dioxide to the atmosphere.
Answer:
The growth rate.
Explanation:
To determine the density of a rabbit population, one would need to know the number of rabbits and the growth rate of rabbit's population because both factors allow us to determined the population of rabbit in a specific region. If we know the existing population of rabbits in a particular area as well as the growth rate at which the rabbit population increases so we can find out the density of rabbit population in a specific time period.
Accuracy describes how well a measuring instrument determines the variable it is measuring. How close the value is to real value. The level of accuracy of measuring tool determines the detail to which it can measure. In order to be accurate in their work scientists need first select a measuring instrument that allows an appropriate measure of accuracy and then to calibrate it. Calibrating an instrument involves measuring already known quantities to check how accurately it is. In the laboratory accuracy of a test is determined when possible comparing results from the test in question with results geenrated from an established reference method.
