The correct option is B.
The area described in the question given above is desert. Most plants in the desert either have small leaves or no leave at all, in order to regulate the amount of water that is lost to the atmosphere via evaporation of water from the leaves. Most deserts are found within the latitude 30 degree north and latitude 30 degree south. Some deserts can also be found around mountain. The temperate range in desert is quite wide. During the day, the temperature may be as high as 50 degree Celsius and the temperature may drop below zero degree Celsius in the night. Thus, it is always very cold at night compares to during the day.
There are many different factors, but some are: the amount of natural resources (food, water, etc.), amount of predator/prey, and availability of shelter.

Answer:
That is administered and controlled
Step-by-step explanation:
A variable is the condition or a product that may vary without the influence of any investigator. Such variables can be found abundantly in our daily lives, ranging from air to sunlight. Controlling such variables ensures the limitation of their influence on the outcome of an experiment. In connection to this experiment, the variables that are controlled are the mineral content in the water, the amount of bacteria food, the amount of light and the the constant temperature of 20 degrees C.
If not administered or these variables controlled, the experiment would not clearly explain the impact of caffeine on the heart beat of the water fleas as other variables may have influenced it. Thus variables are controlled to study the singular impact of any agent or effect.

Melting of glaciers and ice sheets will cause coastlines to shrink and increase flooding.
