Answer:
astronomical unit (AU) and light years
Explanation:
The complete question is as follows:
If a researcher only wanted to examine the relationship between exercise and grade point average, _________ would be used to test the variables.
A. correlation analysis
B. regression
C. hypothesis
D. central tendency measures
Answer:
The correct answer would be - A. correlation analysis.
Explanation:
To find the relationship between two variables the correlation analysis is the statistical method is used. It is used to find the what and how the one variable is related to the other variable in this method.
It is used to evaluate the relationship between any two quantitative variables.To examine the relationship between exercise and grade point average,b this method would be best as it also shows how strong is the relationship of variables.
Petri dishes should always be stored inverted.
In biology, petri dishes are frequently used to produce microorganisms like bacteria, yeast, and mold. The organisms that grow on solid or semisolid surfaces are best suited for it. To reduce the chance of contamination from airborne spore particles landing on them and to avoid the buildup of water condensation that could disrupt or impair a culture, they are often covered and stored inverted.
Aside from that, incubating the media in the normal position could result in the media drying out, which would interfere with the ideal conditions for microbial growth and increase microbial count mistakes. Since the labels are put underneath the plates rather than on the lids, placing plates upside down also makes them easier to handle and recognize.

<span>1)Cellular respiration depends on oxygen as a substrate. </span>
<span>2)Photosythesis utilizes 2 electron transport chains (not just 1). </span>
<span>3)In Photo. , energy is provided by photons and not catabolic processes as in cell. resp. </span>
<span>4)Photosynthesis involves the production of NADPH (CR involves NADH and FADH2) </span>
<span>5)Photosynthesis involves CO2 and H20 as substrates (splitting h20 provides the electrons for the process).</span>
It's definitely not A. since the toxins would kill butterflies. B. doesn't seem relevant. C. doesn't make sense because the toxins in the pollen are to protect the corn not to make new strains. So, the answer would be D. The carbon dioxide level would increase in the area. Hope this helps!
