9. Which of the following human body systems work together for support, protection, and movement? A. the respiratory system and cardiovascular system B. the skeletal system and muscular system C. the skeletal system and integumentary system D. the integumentary system and digestive system

Answers

The Human body system that work together for support, protection and movement is ; ( B ) The skeletal system and muscular system

The skeletal system provides support for every other system present in the human body and it also gives the organism its shape as well. while the muscular system protects the vital internal organs from external shocks.

Both Skeletal and muscular system provide movement, support and protection for the Human body because without any of these the human body cannot make movements or support itself efficiently.

Hence we can conclude that The Human body system that work together for support, protection and movement is The skeletal system and muscular system.

Two substances were mixed and there was a color change and small flames. What can you infer happened?A physical property was observed
A chemical change occurred
A change in state from solid to liquid
Matter was destroyed

Answers

A chemical change occurred

Explanation:

There are two types of changes, physical changes and chemical changes:

A chemical change occurs when the nature of a substance changes, and new substances are formed. This occurs when the bonds between molecules in the reactants break, and they re-form into new substance. A change in the colors of the substance involved is, for example, a sign that a chemical change occurred
A physical change occurs when there is a change in state of a substance, but no new substances are formed. For instance, a physical change is the melting of ice, or the boiling of water, or the condensation of water..

In this problem, two substances are mixed and there is a color change and small flames. The color change indicates the formation of new substances, so a chemical change has occurred. Moreover, the presence of small flames indicates that a chemical reaction has occurred (burning of oxygen), so a new substance has formed, so this is another indication of a chemical change.
