Answer:

B. The foam has tiny air pockets that slow the transfer of thermal

energy away from the water in the pipe

Explanation:

Air cannot conduct heat well and can be used as a good insulator. Poor heat conduction of the insulator. When it is cold outside, the temperature gradient will adapt to the environment. The temperature of the water in the pipe is relatively high. It loses heat to the environment. The foam layer prevents this form of heat exchange due to surrounding air pockets.

Answer:

B. The foam has tiny air pockets that slow the transfer of thermal

energy away from the water in the pipe

Explanation:

Air is a poor conductor thermal energy and can be used as good insulator. Insulators are poor conductors of heat.

When it is freezing outside, the temperature gradient will tend to adjust to the ambient one. The water in the pipe being at a higher temperature will tend to lose heat energy to the surrounding.

The layer of foam will prevent this form of heat exchange from happening because of the air pocket that is present around.

Answer:

- Dependent variable: number of cells that are in one of the phases of mitosis

Explanation:

In an experiment, the independent variable is the variable that is not changed by the other variables that are being measured during the experiment (in this case, the independent variable is represented by the distances from the root cap). On the other hand, the dependent variable is the variable that is being measured/tested during the experimental procedure and, therefore, is 'dependent' on the independent variable. In consequence, in an experiment, the dependent variable is expected to change as a result of the manipulation of the independent variable.
