Answer:
C. Independent variable
Explanation:
The independent variable in an experiment is the variable that the experimenter manipulates or changes in order to effect a measurable response in the dependent variable.
According to this question, an experiment is conducted to determine what concentration of disinfectant is most effective in killing bacteria. The independent variable is the CONCENTRATION OF DISINFECTANT because it is the variable being changed or manipulated.
Answer:
True
Explanation:
ATP – or Adenosine Triphosphate – is the primary energy carrier in all living organisms on earth. Microorganisms capture and store energy metabolized from food and light sources in the form of ATP.
When the cell requires energy, ATP is broken down through hydrolysis. The high energy bond is broken and a phosphoryl group is removed. The energy released from this process is used to drive various cellular processes. ATP is constantly formed and broken down as it participates in biological reactions and it is central to the health and growth of all life. Without it, cells could not transfer energy from one location to another, making it impossible for organisms to grow and reproduce.
ATP is a nucleotide that consists of three main structures: the nitrogenous base, adenine; the sugar, ribose; and a chain of three phosphate groups bound to ribose.
