Answer:
Constant variables
Explanation:
Elaina's investigation lacked the critical ingredient of constant variables which are important components of every scientific investigation. In every research, there are 3 important variables, namely:
1. Dependent variables: the actual variable to be measured during the course of investigations and whose values are dependent on another variable (independent variable) supplied by the investigators.
2. Independent variable: one of the variables that are supplied by investigators whose values are often manipulated to see the kind of changes it will cause to the dependent variable.
3. Constant variables: other variables that are neither independent nor dependent but constant for all the various experimental groups in investigations.

Glucose gets into the cells through a process called facilitated diffusion. This is a transport mechanism in which carrier proteins shuttle molecules across the cell membrane without using the cell's energy supplies and so it is called passive transport. The carrier proteins bind to glucose, which causes them to change shape and translocate the glucose from outside of the cell membrane and into the cell.
(a) glucose is important because it is the primary source of energy for the cell.
(b) Glucose is 6 - carbon monomer of starch. It is a sugar.
(c) Glucose is broken down to pyruvate through the process of glycolysis.
