Your class is growing radish plants in class and collecting data on the dry mass data of the plants and soil at the beginning and end of an 8 week observation period. Which of the following best describes the pattern observed in the radish plant data over time. A: The soil lost a lot of mass, while the radish plant gained a lot of mass.
B: The soil stayed about the same, while the radish plant lost mass.
C: The soil mass stayed about the same, while the radish plant gained mass.

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called

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.'
