Carlos reviewed the data on water use in the united states. carlos wanted to conserve water so he and his father fixed all the leaks in the house and garage. carlos hypothesized that if they fixed their leaks, they would not use as much water as before. what must carlos do to make this a real experiment?
a) determine his manipulated variable.
b) draw a conclusion from the data in the bar graph.
c) collect and analyze data before and after the leaks are fixed.
d) make a prediction about the amount of water used before fixing the leaks.

The correct option is C) Collect and analyze data before and after the leaks are fixed.

Explanation:

The hypothesis that Carlos has generated is that if the leaks in the house are fixed, then the water consumption would be reduced. To check the validity of this hypothesis Carlos must design an experiment in which the dependent variable should be water consumption and the independent variable should be the leaks in the house.

To deduce the results, Carlos must check the usage of water for a fixed period before fixing the leaks and then check the usage of water after fixing the leaks for the same period.

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.
