Cannot be determined, I need more information.
Answer:
B. Randomly assigning students to the two different groups
Explanation:
The bias can be controlled by making use of the randomized block design where we divide the subject into subgroups also called blocks and randomly assign treatment conditions to each block.
In this case, the blocks or sub groups are learning math from a video game and learning it from traditional classroom activities.
So the best way to control the bias is by randomly assigning students to the different groups.
Answer:

Explanation:
I looked it up so it may be wrong
Volume of cube = Length x width x height
= 1 x 1 x 1
= 1 cm cubed.
If this cube is dropped into 28.0 ML of water the new volume reading onthe graduated cylinder = 1 + 28
= 29 mL
A. a large amount of energy released into its surrounding
During the respiration, glucose molecules are converted to other molecules in a series of steps. They finally end up as as carbon-dioxide and water.
The overall reaction is
<span>C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + 2805 kJ
</span>
The reaction is exothermic reaction because <span>C=O and O-H bonds in the products are so much more stable than the bonds in the reactants.

Bond energy is the average needed to break a bond.
Some bond energies are:
C-C = 347 kJ/mol
C-H = 413kJ/mol;
C-O = 358 kJ/mol;
O-H = 467 kJ/mol;
O=O = 495 kJ/mol;
<span>C=O = 799 kJ/mol</span>
