False
( T OR F ) ALL LIVING THINGS ARE COMPOSED OF CHEMICALS
TRUE
( T OR F ) A LONG-TERM RELATIONSHIP IN WHICH BOTH PARTICIPATING SPEICES BENEFIT IS KNOWN AS PARASITISIM.

b. using water and carbon dioxide to produce energy-rich compounds
c. consuming autotrophs
d. consuming simple chemicals from the environment ans using them to assmeble complex chemicals and structures needed by organism
D
Whick example of scientific methodology is incorrect?
a. observation- a # of people in Zaire dying of a disease outbreak
b. measurement - a record of the # of people w/ symptoms of the diesease an the number of people who had died from the disease.
c. analysis of data- comparision of the effects of mixing monkey cells with virus- containing blood in test tubes and the effects of mixing of liquid from these test tubes with fresh monkey cells
d. Inference making - identfication of the Ebola virus as the cuase of the disease by taking electron micrographs of substances found in blood of persons affected with the disease
D
(t/f) frefer to the illustration above. both species have DNA in their cells.
