Answer:
Plants produce oxygen gas and glucose molecule during the process of photosynthesis by absorbing radiation of the sun.
Explanation:
Photosynthesis is a process in which glucose and oxygen are produced by the combination of carbondioxide and water in the presence of sunlight. Carbondioxode is taken in the leaves through stomata and water is absorbed by the plant from the soil. When these two substances combine in the presence of sunlight produces glucose and oxygen.

Answer:
Dependent variable: Number of bug bites
Independent variable: Sprayed arm
Control group: Arm not sprayed.
Experimental group: Sprayed arm
Explanation:
If you know the definitions for the independent variable, dependent variable, control and experimental group in a problem than it would be less complicated to figure out what they are in any given example. So, here are the definitions:
Independent variable: the factor that you change
Dependent variable: the factor that is measured
Control group: the factor that is kept the same
Experimental group: the group in an experiment that receives the variable being tested
