PLEASE HURRY TIMED Cells are open systems that exchange matter and energy with their surroundings. Which of the following best explains why plant cells require sunlight to make organic compounds, according to Gibbs’s theory of free energy? a) The energy input required for making organic compounds equals the usable energy output of respiration.

b) The energy required from sunlight to start photosynthesis is less than the energy needed from another energy source.

c) The energy required to make organic compounds is always greater than the potential energy stored in these compounds.

d) The energy that a plant absorbs from sunlight is spontaneously transformed into chemical energy because the outputs are more stable.

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.
