Answer:

C. Release of Heat Energy

Reason:

-A <u>chemical</u> is any substance that has a definite composition

-A <u>chemical reaction</u> is the process by which one or more substances change to produce one or more <u>different</u> substances

-Matter is anything that has mass and volume

-Solids have fixed volume and shape

-Liquids have fixed volume, but not a fixed shape

-Gasses have neither fixed volume or shape

Evidences of Chemical Change:

1. Evolution of bubbles (gas) without a heat source

2. Formation of a precipitation (solids floating in a liquid)

3. Transfer of energy (it gets hot or cold)

4. Color change

In the part of the question, "They noticed that bubbles form, the test tube got hot, and the magnesium disappeared", it states nowhere about color change or change in odor.

Question 1:
Basically, producers are things like plants the are the first source of food. Primary consumers are the first to eat the producers (like small fish, insects, etc) Secondary consumers (foxes, larger fish, etc) consume the primary consumers, and tertiary consumers (sharks, humans, whales, etc.) consume the secondary consumers. Decomposers (fungi, bacteria, etc) like the name suggests decompose rests of food and organisms and send the nutrients back into the earth.

Questions 2&3:
An autotroph is an organism that produces its own food (like plants do through photosynthesis) and a heterotroph is an organism that cannot produce its own food and has to seek out other sources of food.

Question 4:
Grass, Dragonfly, Trout, human

Question 5:
Bean plant, rabbit, fox, bacteria

Questions 6&7:
They are a little harder to explain in text form but hopefully my explanations can help you figure out the answer yourself.

Hope this helped!

Physical trauma, acute disease, chronic disease, infectious disease and emotional trauma are the ways from which health should be affected by happening of natural disasters such as earthquake and cyclones. We are able to predict the weather with the help of satellites that monitors the movement of clouds on the earth atmosphere. Advancement of technology is the main reason which enable us to predict the weather conditions as well as the coming of cyclones in a specific region.
