Answer:
Observation: Fertiliser produced tall pea plants
Hypothesis: Pea plants grown in the soil with the addition of fertiliser will grow taller than pea plants without fertiliser
Independent variable: Fertiliser
Dependent variable: Growth of plant
Control group: 5 pea plants in the pot without fertiliser
Experimental group: 5 pea plants in the pot with fertiliser added
Qualitative or Quantative data: Qualitative
Explanation:
Observation is using your senses to describe what you see.
A hypothesis is a prediction.
The independent variable is what you change in an experiment.
The dependent variable is what changes as a result of the independent variable. The dependent variable is what is measured in an experiment.
The experimental group is the group of subjects in an experiment which are exposed to the independent variable.
The control group is the group of subjects in an experiment which are not exposed to the independent variable.
Qualitative data is data that can be described but not measured. Quantitative data is data that can be measured.
Answer;
Mitosis
DNA replication occurs right before mitosis
Explanation;
-DNA replication
is process of making new cells
where a DNA molecule is used as a primer to form new DNA strands. The process is catalyzed by DNA polymerase enzyme to form new strands of DNA that have one new strand and another one from the original DNA.
-Mitosis is a type of cell division that occurs in the body cells which involves a cell dividing into two daughter cells that have the same number of chromosomes as the parent cells.
