Answer:thus, there are various methods to measure photosynthesis:
Uptake of CO2 by plants: Since CO2 is needed for photosynthesis, measuring how much of it is taken up by the plants gives us information on how much of photosynthesis is happening.
Release of O2: The amount of O2 produced during photosynthesis can be measured.
Explanation:
1 the atmosphere because gas is everywhere.
The nurse should obtain the specimen from the catheter.
One of the tests from urinalysis that frequently got contaminated is about infection. The area near the orificium of uretra is near the skin, so there will be microbes around it that can contaminate the sample. The contaminated sample will give a false positive and the result will show the urine are infected.
Taking the specimen from catheter will prevent that contamination, thus giving a better sample.
The correct answer is C. Here's why:
Choice A is illogical. A single experiment does not confirm a theory as true. Multiple successful trials are needed for one to even consider a hypothesis to be accepted as a theory.
Choice B is wrong. If a scientist finds a new way to test a hypothesis, experimental methods do change. Note that when there are additional ways to test a hypothesis, a scientist should test it with additional methods.
Choice D is incorrect. If someone finds a way to test a new hypothesis, it would not be made into law since there is more information regarding the theory. This means that it would remain a theory until one can prove that it can't be tested using different methods.
An ecological niche is an organism's specific habitat in an ecosystem.
It is where it lives and feeds, etc.
