Answer:
C. experimental
Explanation:
Experimental variables are the variables that are changed during the experiments to observe the effects of these changes. An experiment usually has one or more experimental variables. An experimental variable that is changed to know its impact on some other variable is called the independent variable.
In the given experiment, goldfishes were exposed to various temperature conditions to observe the effect of temperature on respiration. Therefore, both temperature and respiration rate are the experimental variables here.
Answer:Nucleotids
Explanation:
Many plants have waxy coatings on some surfaces. This coating reduces water loss because it is not water-permeable. This waxy coating is which type of organic molecule? a biomolecule that is a large, complex set of chains composed of alternating subunits called nucleotids has what function in the cell?
The answer is B.
These elements are among the most important elements in life. Most of these elements are also non-metals. Elements life sulfur and nitrogen combine with carbohydrates to form among acids rings like cysteine. Carbohydrates combine with phosphorus to form molecules such as the DNA backbone chain.
Cell division is simpler in prokaryotes than eukaryotes because prokaryotic cells themselves are simpler. Prokaryotic cells have a single circular chromosome, no nucleus, and few other organelles. Eukaryotic cells, in contrast, have multiple chromosomes contained within a nucleus, and many other organelles.
