A scientist wants to test the effect of water temperature on the success of developing frog embryos. The scientist monitors developing embryos in different water temperatures and counts the number of embryos that mature into tadpoles.

Why should the scientist keep all variables except water temperature constant?

to ensure at least some embryos develop into tadpoles

to protect the developing embryos

to test multiple variables at once

to ensure that the results only reflect changing temperature

The scientist should eep all variables except water temperature constant because to ensure that the results only reflect changing temperature. Thus, the correct option is D.

What is Embryo?

An embryo may be defined as an unborn or unhatched offspring in the process of development. It is also characterized as the early stage of the development of multicellular organisms.

Here, scientists should keep all the variables except water temperature constant because they are analyzing the effect of only water temperature on the growth and maturation of a frog's embryo into mature tadpoles.

Therefore, it is well described above.
