The correct answer is: b. it doesn’t often reflect reality.
While experimental research has several advantages, including: investigating the effect of one variable on another, and the ability to control and eliminate confounding variables, it also has one major disadvantage. This disadvantage is known as: <em>lack of ecological validity</em>.
Lack of ecological validity means that the findings of research study might not be generalizable to real-life settings, and might only apply to laboratory settings. To avoid the problem of ecological validity, and to increase the validity of an experimental research study, a study should be conducted in natural settings when possible.
Answer:
The correct answer is a. Pseudomonas aeruginosa would be colorless on EMB
Explanation:
Pseudomonas aeruginosa is a gram-positive bacteria that is rod shape. It shows a few nutritional requirements and can even adapt to those conditions in which the other bacteria can be adapt.
It is non-fermentative bacteria so it does not ferment lactose and other carbohydrates. As EMB agar contains lactose and some dye, therefore, the lactose fermenting bacteria ferment the lactose and show good growth and color change.
But as Pseudomonas aeruginosa is a non-fermentative bacteria it does not ferment lactose and does not show any color and forms a colorless colony. Therefore the correct answer is a.
Answer:
I believe it's c I could be wrong but I'm pretty sure
Out of the following given choices;
a) The amount of oxygen produced
b) The rate of ATP synthesis by ATP synthase in the chloroplast
c) The rate at which NADPH is produced
d) The rate at which the protons are transported into the thylakoid
The answer is; A
The photosystem captures energy from sunlight and uses it to split a water molecule. After splitting the water molecule (by taking an electron), the protein complex transports the electron to plastoquinone. The splitting of water molecules results in evolving of oxygen molecules. The hydrogen is what is used to reduce carbon dioxide to glucose.
A is correct
The slides would have the specimen on it as well
