I believe the answer is C - A company opens a new factory and employs more workers.
Can not be determined
BMR is known as Basal Metabolic Rate which requires information about person's height, weight, age and gender to determine the number of calories burned by a person in a day.
But here only number of calories i.e. 1300 is given which is not enough to find out Alex's Total Energy Expenditure (TEE) as there is no detail about his height, weight and age is given.
Average BMR in the USA:
For Women it is 1493 calories.
For Men it is 1662 calories.
BMR is different from BMI (Body Mass Index) because to find out body mass index only the data related to height and weight is required.

Answer:
The correct answer will be-
1. independent variable- the type of fertilizer
2. dependent variable- height of the plants
3. control group- The quadrant without any fertilizer treatment
4. Importance of control group- acts as reference to the experimental group as is performed without the key component in natural conditions.
Explanation:
A scientific experiment contains three types of variable and is divided into two types of group of samples.
The variables studied in the experiment are;
1. Independent variable: parameter which changes or is induced to change as per the demand of the experiment like the type of fertilizer in the experiment.
2. Dependent variable: parameter which depends on the independent variable and has to be studied in the experiment like the height or growth of the plant.
3. Control group: the group of samples left untreated in which the key component like fertilizer is not provided. So, the quadrant without any fertilizer treatment will be considered the control group.
