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:
a pure substance because it cant be divided/ separated into parts
The answer is jellyfish :)
I believe the correct answer among the choices listed above is option B. A gland secretes enzymes through a duct onto the surface of a body part is a salivary gland. It is under the classification of exocrine glands. Hope this answers the question.
B
<u>Temperature</u> is NOT a density-dependent factor affecting population growth
Explanation:
Density-dependent factors mean variables that are affected by the density of the population. The opposite of density-depend is density-independent factors. These are those variables that affect the density of the population but are not affected by the density of the population.
In this case, temperatures are not affected by the density of the population. However, temperatures affect the density of the population. Most individuals can only survive within an optimal temperature range.
The rest of the choices are density-dependent variables
