The question was incomplete as the question part was missing. however, the correct question is as follow:
Which statement best explains why the researchers’ conclusion was not justified?
The experiment tested too many variables.
The control group was not treated the same as the experimental group.
The sample size of twenty-four petri dishes is not large enough.
The single type of bacteria is not adequate to make any conclusions.
Answer:
The correct answer is - The control group was not treated the same as the experimental group.
Explanation:
In this research, the researchers made two groups experimental group and control group, these groups are meant to get the same treatment except the variable to be measured so they can compare the result.
Here the experimented group was left open while the control group was left closed which lead to the fact the bacteria propagate through the air and not the hand
Thus, the correct answer is - The control group was not treated the same as the experimental group.
All plant and animal cells include the chemical compounds adenosine diphosphate and adenosine triphosphate, sometimes known as nucleotides. The equation can be written as ADP + P + energy = ATP.
<h3>
What is a chemical equation?</h3>
All plant and animal cells include the chemical compounds adenosine diphosphate and adenosine triphosphate, sometimes known as nucleotides.
A high-energy phosphate group is added to ADP to convert it to ATP for energy storage. The conversion occurs either in mitochondria, which are specialized energy-producing structures or in the cytoplasm, the fluid-filled space that lies between the cell membrane and the nucleus.
Adenosine diphosphate with inorganic phosphate plus energy results in adenosine triphosphate, which is the product of the conversion of ADP to ATP.
Therefore, All plant and animal cells include the chemical compounds adenosine diphosphate and adenosine triphosphate, sometimes known as nucleotides. The equation can be written as ADP + P + energy = ATP.

<u>Answer:</u>
<em>Biomagnifications largely affects the organisms at the highest trophic level.
</em>
<u>Explanation:</u>
The increase in concentration of toxic chemicals while moving up in a food chain is called biomagnification. What starts out as a small concentration at the lowest trophic level turns out to become a <em>higher concentration at higher trophic levels. </em>
Thus it is the organisms at the highest trophic level that are the most affected. This accumulation occurs because the organisms have not evolved enough to posess mechanisms that <em>facilitate detoxification of various substances. </em>
Such substances are called novel substances and DDT is an example. Removal of substances like metals is also difficult. Thus a harmful chemical component travels up various trophic levels increasing in <em>concentration at each trophic level.
</em>
When heating food in the microwave, it must reach a temperature of 165 degree Fahrenheit. This is necessary in order to reduce dangerous micro organisms in food to safe levels. Thermometers can be used to verify the final temperature.
<span>The correct answer is B. Human activity. That's why it is said that global warming si not natural because it's human created. This usually means that things like deforestation or usage of fossil fuels or freon or similar things brings climactic change, usually for the worse. Other mentioned aspects are all found in nature and are not something that we can affect. </span>
