A scientific claim is developed by answering questions raised through suitable hypotheses that allow making predictions, which can be tested by experimental procedures.
<h3>What is a scientific claim?</h3>
A scientific claim is a body of knowledge obtained by answering the equation formulated through the observation of the real world.
These observations are capable of raising plausible explanations or hypotheses that can be tested (confirmed or rejected) by using the scientific method.
An inquiry activity may be, for example, the observation of the movement of a cylinder in aqueous solution.
In conclusion, a scientific claim is developed by answering questions raised through suitable hypotheses that allow making predictions, which can be tested by experimental procedures.

Answer:
The correct answer would be the harmless bacteria had been transformed.
Griffith used two different strains of the bacteria <em>Streptococcus pneumoniae - </em>type-III-S or smooth strain and type II-R or rough strain.
Smooth strain had protective covering around itself (protect itself from hosts's immune system) and was able to kill the mice.
Rough strain did not have any protective covering around itself and thus could be easily removed by the immune system Hence, it was not able to kill the mice.
In addition, heat killed smooth strain was also not able to kill the mice. However, when remains of it was added with rough strain then the blend was able to kill the mice.
Lastly, he was able to isolate living bacteria of both the strains.
He concluded that non-lethal type II-R strain was transformed into lethal type II-S strain by "transforming principle" (which we know today as DNA) that was supposed to be the part of dead III-S strain bacteria.
Spirogyra<span> is a genus of filamentous charophyte green algae of the order Zygnematales, named for the helical or spiral arrangement of the chloroplasts that is diagnostic of the genus.

<h2>Cellular respiration </h2>
Explanation:
- Cellular respiration is defined as a ATP generating process in which organic molecule is oxidized and inorganic molecule is final electron acceptor
- Pain experienced in leg muscles is the result of formation of lactic acid in muscle cells
- Under low oxygen, NADH cannot be reoxidized to NAD+ but NAD+ is required as an electron acceptor to continue glycolysis
- In lactic acid fermentation pyruvate is the final electron acceptor and converted in lactate
- Reaction catalyzed by lactate dehydrogenase
- The pain in her chest is caused from the lack of oxygen she received while running so her chest starts to heavily breathe so that the lungs can receive as much oxygen possible
Answer:
Explanation:
- Fertilizer during runoff
- Heat, and radiative chemicals
- Yards and runoff
- Heating the water if run by steam by pumping the waste into rivers
- The clean water act focuses on navigation and water as in fishing, and swimming water while the safe drinking water act dictates how water comes to our cups from their original sources.
- You can get information by any sites locally about disposing chemical waste or any government website ending in .gov
- Home waters including sewage have to be filtered through heavy chemical processes using extra waters and factories. our clean water volume is plummeting.
