Answer:

C. Release of Heat Energy

Reason:

-A chemical is any substance that has a definite composition

-A chemical reaction is the process by which one or more substances change to produce one or more different 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.

Which is not correct about type 1 diabetes? which is not correct about type 1 diabetes? the immune system destroys the insulin-p

olganol [36]

Choice (B) is the only incorrect statement about Type 1 diabetes. Insulin is not produced in the pancreas by a person with this disease, because the cells that do this type of work have been attacked and destroyed by one's own system. This requires daily insulin injections and constant maintenance, beginning in childhood.
