Answer:
The need for DNA replication
DNA replication is the process by which a cell makes an identical copy of its DNA. This process is performed at the beginning of every cell division so that when the cell divides, each daughter cell will inherit an identical copy of the DNA.
Requirements for DNA replication
Original DNA template - DNA is a double helix made of two complementary strands. Each strand can be used as a template to create a new DNA molecule.
Free DNA nucleotides – needed to form the new strands.
DNA polymerase – an enzyme that adds new nucleotides to a growing strand of DNA.
Primers – A primer is a short strand of nucleotides that will bind to the 3’ end of the template DNA strand allowing DNA polymerase to add free DNA nucleotides.

White blood cells (D) aid in the immune system to fight infections.
The stages of mitosis are:
1. Prophase
2. Metaphase
3. Anaphase
4. Telophase<span>
Prophase
This is when the </span><span>centrioles separate and move to opposing sides of the cell.
Metaphase
This is when the chromosomes line up in the center of the cell and become connected.
Anaphase
This is when the</span><span> "sister" chromatids separate into individual chromosomes and are pulled apart.
Telophase
This is the last phase of mitosis, when chromosomes gather at opposite ends of the cell and new nuclear membranes form.
The answer is metaphase, because that is when the chromatids line up in the center of the cell.

Answer:
a. Manipulated variable: TEMPERATURE
b. Responding variable: CRICKET CHIRP
c. Controlled variable: Same species of cricket
d. Hypothesis: IF the temperature is increased, THEN crickets will chirp more
Explanation:
Independent variable, also called the manipulated variable, is the variable that is changed or manipulated in an experiment. In this case, the independent variable is the TEMPERATURE.
Dependent or responding variable is the variable that responds to changes made to the independent variable. The dependent variable in this case is CHIRP OF THE CRICKETS.
Controlled variable is the variable that must be kept unchanged for all groups throughout the experiment. The controlled variable in this case is SAME SPECIES CRICKET USED.
Hypothesis is a testable explanation (via experimentation) to an observed problem or a given question. In this investigation involving Melissa, an hypothesis is: IF the temperature is increased, THEN crickets will chirp more.
