Gerald performed an experiment to determine if photosynthesis was affected by the amount of light that a plant received. the data from his experiment are shown in the table below.

amount of light number of plants average volume of oxygen
produced (ml)
(hours)
1 4 0.50
6 4 2.00
10 4 5.00

which format should he use to present his data?

bar graph

chart

line graph

pie graph

Line graph

Explanation:

The most appropriate is a line graph because the experiment aims to show the changes of the plant over time. A line graph can express or show changes in values an in turn, it can show how one variable affects the other.

Attached is a rough example of a line graph of your data.

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
