Traveling Buses: show question from ActivBoard. Answer only part B.
B.Tell approximately how far each bus traveled in 4 hours
What is must use the word approximate and then be close to the actual speed.
200
An abiotic resource is...
What is a resource that is not living.
200
Name one disadvantage to asexual reproduction.
What is offspring is identical to the parent.

When solutions of sodium chloride and calcium carbonate are combined, a chemical reaction occurs. Show question but only answer part C.
C. What is the name of the compound missing from the products in the chemical reaction?
Explain your reasoning for your answer.
What is sodium carbonate. Explanation must be explained well and show the process of elimination must be used.
300
You have 2 substances: Vinegar and Baking soda. You mix the two…
Show full question but only answer part B.
B. The mass of the solution after the reaction did not equal the mass of the baking soda and vinegar before the reaction. Describe one reason why the mass of the solution after the reaction was different from the mass of the baking soda and vinegar after the reaction
What is answer must include, the law of conservation of mass says that matter cannot be created or destroyed so in a chemical equation both sides of the equation must be equal. In this case both sides will not equal because some of the mass was released through bubbling.
300
Traveling Buses: Show question from ActivBoard only answer part C.
C.Predict the future of each bus.
What is must have these in the answer to get credit... If both buses continue at this constant speed then Bus A will reach its destination first because it is going faster. We know this because the diagonal line is steeper.

What does biotic mean?
What is living or was once living.
300
Name one advantage of sexual reproduction.
What is genetic variation. This words must be used to get credit. Genetic variation describes naturally occurring genetic differences among individuals of the same species. This variation permits flexibility and survival of a population in the face of changing environmental circumstances. Consequently, genetic variation is often considered an advantage, as it is a form of preparation for the unexpected.
