Isolating a single bacterium species is the first step in identifying the bacteria possibly responsible for a disease process.
Explanation:
Answer:
B) Styrofoam is a good insulator.
Explanation:
When talking about thermal energy, or a heat, insulator is a material that doesn't allow heat to pass through easily. On the other hand, a conductor is completely the opposite, it allows, quite successfully, transfer of the heat.
So, regarding ice cream, from these definitions above, we can conclude that insulators will prolong melting time, while, in the conductors, ice cream will melt rather fast.
Looking at the table, we see that Styrofoam had the longest melting time, which makes it quite successful insulator.
Answer:
In the experiment conducted by Alisha to test the effect of different materials on the melting rate of ice, the dependent variable is the mass of the ice, and the independent variable is the type of cover material.
Explanation:
During an investigation or experiment, the dependent variable is the one whose changes will be studied, while the independent variable is able to influence the changes of the dependent variable.
In the case where it is wanted to <u>measure how different cover materials affect the rate of ice melting</u>, the dependent variable is the mass of ice and the independent variable is the coverage material, capable of affecting the time it takes for the ice to melt.
