You have formulated a hypothesis: "Blueberries contain more vitamin C than raspberries." To test your hypothesis you measure vitamin C levels in 20 blueberries and 20 raspberries from bushes that were grown in the same area under the same environmental conditions (temperature, rain, sunlight). What is the dependent variable in this experiment?

(A) The type of soil, temperature, amount of rain and sunlight in the area
(B) Vitamin C levels
(C) Blueberries
(D) Raspberries

The correct answer is B) Vitamin C levels.

The dependent variable in this experiment is Vitamin C levels.

When we are talking about research, a dependant variable is the one that is being tested in the research. The scientific approach, in this case, is the amount of vitamin C in raspberries and blueberries. What researchers try to measure is the dependant variable that is vitamin C in each of those fruits.  

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
