A controlled experiment is when the experimenter can change one variable in the experiment and completely change the results.
Redi experiment involved a closed jar with rotting meat on the inside. He waited for a few days and found no new forms of life in the jar.
He then did the same experiment, but this time he took the lid off the jar. After those few days he found there were maggots in the rotting meat from flies.
This is a great example of a controlled experiment, because he only had to change one variable to completely change the results. In this case that variable was just removing the lid from the jar.
Redi was trying to prove spontaneous generation with his experiment. Although, it failed.
Spontaneous generation: When life forms from non-livings.
Redi disproved spontaneous generation, but proved biogenesis.
Biogenesis: When life comes from other living beings.
He proved biogenesis because the flies had reproduced when the jar was opened.
Hey there mate!
Based on my information to this, I believe sense (it would be a closed system), this would most likely be considered to be (equal to) the total energy after.
But, if it was not a (closed system), it would not be unrelated because the energetic system would not be that greatly increased.
So, it really depends whether the system closes up, or whether it would be free of energy.
So, in this case, your correct option to this answer would be (option A).
<span>In a closed system, the total energy prior to an energy transformation is unrelated to the total energy after.
I hope this helps you!</span>
The answer is <span> b. a process of change through time.
Evolution is a process of change through time. It does not result in progress. Natural selection, one of the mechanisms of evolution, can result in progress and </span>cause some organisms to develop characteristics they need. But generally speaking, natural selection is not the only mechanism of evolution. Other evolutionary mechanisms, such as genetic drift, mutations, migration, can in some cases have a harmful outcome.
Cellular respiration is the process of releasing energy from the food that one had taken. The reactants of the cellular respiration were both oxygen and glucose. The main product of this process would be ATP (adenosine phosphate) but could also be H2O and CO2.
Answer:
Because flu viruses evolve so quickly, last year's vaccine may not protect you from this year's viruses. New flu vaccines are released every year to keep up with rapidly adapting flu viruses.
