Which of the following is NOT an assumption that scientists make when doing experiments?

Question

a. There is no reasonable alternative to their hypothesis.
b. Another person would record the same results.
c. Only natural causes are involved.
d. The same thing would happen at other places and times.
e. All of the above are assumed.

5. What happens in a controlled experiment?

a. Everything is allowed to vary between treatments.
b. The treatments differ in only one way.
c. All the experimental subjects are the same.
d. Only one experimental treatment is used.

9. Which level of a food web requires most photosynthesis to sustain a given amount of biomass (living matter)?

a. the primary producers, for example plants
b. the herbivores, eg. caterpillars
c. the carnivores, eg. mountain lions

Answer 1

A-should always be open to new theories to match your results.
B-evrything but what your testing is controlled.
A-plants use photosynthesis in thier cells.

Answer 2

A - The assumption of an alternative is intrinsic to the experimental process

B - That is the point of a control. If two or more variables are permitted it is impossible to ascertain which variable caused a different result.

C - Plants grow. Herbivores eat more than one plant. Carnivores eat more than one herbivore. The energy density increases at each level.

Answer 3

How about instead of someone doing your homework for you, you actually read your textbook (which I assume is covered in dust due to lack of usage) which should have the answers.

Answer 4

C, D, and A. I think. I'm not gonna down you for needin' help. I used to do our chemistry and my bf used to do the geometry; which I did eventually learn! Good luck.

Hope I'm right. But you should still study and do your own homework, I could be wrong lol.

Answer 6

do your own home work!
