Answer:
D. oxygen and high-energy sugars
Explanation:
Photosnthesis is essentially the opposite of cellular respiration, meaning that if cell respiration is oxygen and glucose in, carbon dioxide out, then photosynthesis is cabron dioxide in and oxygen and glucose out.
Theories are often the best explanations of natural phenomena we currently have. Yet, what one has to realize is that science is ever changing. That is why (B) is the correct answer, as new examinations, experiments, and discoveries could change some of these well-accepted theories. There is no way to "harm science" with viable observations and discoveries so (A) is incorrect. Answer (D) is also wrong since there is no assurance that a theory will never change in the future as they are merely accepted hypotheses. Answer (C) is not the best answer since theories are usually well supported and wouldn't be veritable if every examination proved flaws.
Hope this helped! :)
The ability of an organism to survive and reproduce in its environment is called adaptation. Fitness is a result of adaptation.
Answer:
Experimental set up in the lab.are under the control of the scientist,therefore they can manoeuvre the the surrounding conditions to suit the experimental set up for best results. In addition the lab.environment does not involve the complex interactions or reaction between the set up and the lab. environments, compare to the natural environment.
Natural experimental set up gives accurate results from the interaction of the organisms(e.g animals) under investigation in the natural environments,thus the results obtained are natural interaction of the organisms based on the environmental factors the organism are exposed to.However, the number of organisms are usually large,and therefore great effort is needed to determine the actual cause and effects of the factors affecting the organisms under investigations in this natural environments.
