The answer is B. Natural Selection
At higher concentrations, it catalyzes the collisions. think of it like a glow-stick. the smaller ones aren't a bright because less chemicals are inside the tube, but large glow-sticks are brighter, and has more chemicals contained in the tube. the correct answer is 3, the catalyst answer. <span>At higher concentrations, product molecules are able to catalyze the reaction.
hope this helped. good luck!

Answer:
<em>Which arrow or arrows represent a release of carbon dioxide? What process is occurring at the arrow(s) you selected?</em>
- From factory emissions to carbon dioxide in atmosphere (<u>C</u>)
- The process occuring can be called as <em>Combustion</em>. In this process, organic matter is burned in the presence of oxygen (oxidizer). It releases energy and carbon dioxide because carbon in organic matter is oxidized to form CO2.
<em>Which arrow or arrows indicate a process that cycles carbon from living or nonliving organisms? Describe the process or processes you selected.</em>
- from dead organisms to fossils and fossil fuels (E)
- The process explained in the question can be stated as <em>Fossilisation</em>. In this process, dead remains of plants and animals are transformed to fossils under pressure. The organic matter is preserved according to the shape of organism.
<em>Which arrow or arrows represent reactions that demonstrate conservation of mass and energy? Explain your answer.</em>
- from factory emissions to carbon dioxide in atmosphere (C) & from carbon dioxide in atmosphere to photosynthesis (B)
- Two reactions represent the converstion of mass and energy. The burning of fossil fuel (mass) releases energy and carbon dioxide, which is again used by plants to store energy in the process of photosynthesis. This is shown in C and B part of the figure.
The statement about physical activity and weight loss and maintenance that is most accurate is, option A. Regular physical activity helps control the percentage of body fat in children and adolescents. Regular physical activity should be maintained by all age groups, but each varies on the optimal amount of activity they need.
Both processes rely on each other to function
