A student wants to compare the amounts of CO2 given off by yeast provided with different amounts of sugar. The student places a balloon over each container to catch the released CO2. Which observation is a qualitative observation the student can make? O A. A description of the shape of each balloon B. A measurement of the approximate size of each balloon C. A measurement of the circumference of each balloon D. A visual count of individual CO2 molecules in each balloon PREVIOUS

The answer is letter (A): A description of the shape of each balloon

Explanation:

Qualitative observations are descriptions and not measurements or countings. For example, the shape of the balloon is a quality unlike the measurements of circunference, size or amount of molecules.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
