marble with same force on all four surfaces?
A. Data collection
B. Dependent variable
C. Independent variable
D. Experimental constant
D -- Photosynthesis occurs in many prokaryotes and eukaryotes, where areas oxidative respiration
occurs in only aerobic prokaryotes and eukaryotes
** Explanation: Photosynthesis occurs in bacteria, certain protists, and plants. Oxidative respiration

digestive organ -

observed data. This strategy allows for experimental testing -
"Dark matter" is a form of energy proposed to explain the repulsive forces between
matter in the universe. It has never been observed directly. Which of the following is the best
rationale for many scientists' contention that it exists?
A. It serves as a working hypothesis to explain real observations in the universe
B. A basic scientific principle is to consider everything possible until proven otherwise
C. Since light energy exists in the universe, dark energy must also exist
D. Light energy from distant stars is very faint because it is absorbed by dark energy
