Answer:
The null hypothesis is incorrect.
Explanation:
The null hypothesis is incorrect because the average number of bacteria did not remain the same at the source and at the outlet. We know that bacteria reproduce in a very less time and they use reproduction methods such as binary and multiple fission so with the passage of time, the population of bacteria increases and did not remain the same at the source and at the outlet.
Answer;
Prophase
Explanation;
-Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell divides once to form two identical cells.The major purpose of mitosis is for growth and to replace worn out cells.
-Mitosis is divided into five phases: Interpase, prophase, metaphase, anaphase and telophase.
-During prophase; the chromosomes condense into X-shaped structures that can be easily seen under a microscope. Each chromosome is composed of two sister chromatids, containing identical genetic information. The chromosomes pair up so that both copies of chromosome 1 are together, both copies of chromosome 2 are together, and so on.
-At the end of prophase the membrane around the nucleus in the cell dissolves away releasing the chromosomes.
