Answer:

The correct answer is movement; structure.

The muscular system helps with <u>movement</u> and the skeletal system helps with <u>structure</u>.

The muscular system and the function of the muscles allow the movement of our body and it is the one that works in tune with other systems of our body to guarantee normal general functioning..The skeletal system is the set of organs that support, shape, structure and protect the body. The skeleton is a dynamic structure, specifically the axial skeleton, it is to serve as a support or as a scaffold that supports the organs and structures of the body. This is how bones together with muscles work as a team to allow the mobility of the human body.

Which statement is best supported by the data in the graph?  A graph entitled Number of people living with H I V, number of people newly infected with H I V and number of AIDS deaths worldwide from 1990 to 2008 in millions is shown. Year is on the horizontal axis and number of people is on the vertical axis. The number of people living with H I V steadily increases over the years. The number of people newly infected increased from 1990 to 1996 and then began to decrease. The number of deaths due to AIDS increased from 1990 to 2002, and then began to level off and decrease.

A. Since 2000, there has been an increase in the number of people living with HIV, but a decrease in the number of people newly infected with HIV.

B. Since 1990, both the number of new HIV infections and the number of deaths due to AIDS has consistently increased

C. The life span of a person living with HIV has become shorter.

D. Twice as many people were living with HIV in 2008 than in 2000.

 Answer:

A. Since 2000, there has been an increase in the number of people living with HIV, but a decrease in the number of people newly infected with HIV.

Explanation:

According to the data shown in the graph, since 2000, the people living with HIV has been increased, but a decrease in the number of people newly infected with HIV.

The reason behind this can be early screening of the infection since 2000 and awareness among people decreasing the infection rate as well.

Hence, the correct option is A.
