Hydrogen: It is the simplest structure which form bond with oxygen and form the water, which is the most crucial component for the most living organisms on earth.

Nitrogen: It is composing 80% of the air and earth. It is very important element in plant life, because nitrogen is readily absorbed and used by plant.

Which statement describes Redi's experiment, which helped disprove spontaneous generation?
Lelu [443]

Answer:

He examined covered and uncovered meat to determine that maggots came from eggs.

Explanation:

Prior to Redi's experiment and other supporting experiments, it was formerly believed that life could emanate from non-living things, for example, the generation of maggots from rotting meat.

In 1668, a scientist called Francesco Redi disproved the idea of spontaneous generation. He did this when he experimented that the maggots from meats are only as a result of eggs laid by flies when they perched on the meat.

He placed the meat in two jars; an uncovered jar and another in a covered jar with a cloth, after several days, the uncovered jar had maggots on the meat, while the covered jar had no maggot on the meat, but on the cloth. With this experiment, he was able to demonstrate that the maggot arose from the eggs of the flies, not the meat itself which is nonliving and hence, disproved the idea of spontaneous generation.

How does the precision of measurements affect the precision of scientific calculations?
juin [17]
<span>The precision of scientific calculations is limited by the measurement that's the least precise out of all the measurements used in the calculation. When considering significant figures, the last answer should have the least significant figures out of all the measurements that entered into account and were able to be done with the most significant figures that could be directly measured. So, as more precise we are in measurements, more precise can be the final answer to a scientific calculation.</span>
