Answer:
The constants: 14 hours of light per day; food one time per day 5 oz; wheel for exercise; cage size
The independent variable: the temperature
The dependent variables: length and weight
Data to be collected: weight of mice; length of mice
A flaw in the experiment: the sample size is to small to be random; it doesn't specify a control group
Explanation:
The constants are the controlled variables. The scientist controls these items because a variable that remains unchanged prevents it from having any effect on the outcome.
The independent variable is the condition manipulated by the scientist to see its effects.
The dependent variables are the ones being measured or tested for in an experiment.
Randomization means every subject gets an equal chance at being in the control group. There are to few subjects. A control group would consist of elements that present exactly the same characteristics of the experimental group, except for the variable applied to the latter.

The challenges/limitations in rainwater harvesting in urban areas include the following:
<h3>What is Rainwater harvesting?</h3>
This involves the collection and storage of rain water from roof tops etc. The water is then used for agricultural activities.
The remedial measures for the challenges mentioned above include the following:
- Unpredictable Rainfall- Weather forecasts and efficient storage
- Regular Maintenance- Use of standard materials and efficient drainage system
