A student is interested in the behavior of fish. He has 4 fish bowls and 20 goldfish. He puts the same number of fish in every bowl and puts them under light. He changes the temperature of each fish bowl, and he observes the behavior of the fish. What can the student find out from doing just this experiment?
A.If the temperature of the fish bowl and the amount of light affect the behavior of the fish.
B.If the temperature of the fish bowl affects the behavior of the fish.
C.If the number of fish, the temperature, and the amount of light affect the behavior of
D.If the number of fish in the fish bowl affects the behavior of the fish.
Answer:
B
Explanation:
The student is changing the temperature of each bowl. He has the same number of fish in each bowl so he will not be able to see if the number of fish in each bowl affects their behaviour. The light is above every bowl so he will not be able to assess if that changes their behaviour either
A student wants to find out if the amount of bleach has an effect on stain removal.
He plans to use two white shirts, stain each of them with mustard, and then wash each of them using bleach. He can change the size of the stain on the shirt and the amount of bleach he adds to the water.
Which test should the student set up?
Answer:
The second option.
Explanation:
We're trying to test the amount of bleach that has an effect on the stain so that is the altered variable.
The 2nd option uses different amounts of bleach to clean the same amount of stain.
If you choose the other options, people can argue that the bigger stain would be harder to clean with one cup of bleach, whereas the small stain gets two cups or the other way around.
It's not an effective way to see if the amount of bleach has an effect on stain removal.

1. Bacteria can reproduce in as little as 20 minutes. Protists and fungi take hours or days to double in number or size. Why can bacteria reproduce at a much faster rate?
2. It takes 1-2 days from the time you catch a virus until you feel any symptoms. What is happening during that time?
3. How can asking a patient when his or her symptoms started help the doctor diagnose that person with a particular pathogen?
4. What challenges do you think doctors encounter when they try to diagnose patients with symptoms that are common to different pathogens?
5. Which pathogen do you think responds faster to treatments provided by doctors? Explain your reasoning.
Answer:
The 4th one is the correct answer
Explanation:
Answer: Down
Explanation:
Bacteria are prokaryotes while protists and fungi are eukaryotes.
Cells are largely classified into two; prokaryotic cells and eukaryotic cells.
Prokaryotic cells do not have a nucleus or organelles while a eukaryotic cell has a nucleus and organelles.
Because bacteria are prokaryotic cells, bacteria reproduces via a process called binary fission which occurs very rapidly.
Protists and fungi are eukaryotic cells and undergo a more complicated process of reproduction.
As a result of this, bacteria can reproduce in as little as 20 minutes while protists and fungi take hours or days to double in number or size.
