An experiment is a type of research method used for scientific investigation to check how a natural phenomenon works and how a particular variable affected by causing or manipulating one variable.
The affected variable called the dependent variable and the variable that is changed is called the independent variable. Other than independent variables other variables should be controlled so there would be no influence on the result other than independent varibles.

In a science lab report, you would usually include a discussion of any errors in the experimental data.
Answer:
Please find the diagram attached and explanation below.
Explanation:
Mitosis is a type of cell division that forms two genetically identical cells. It involves four stages viz; prophase, metaphase, anaphase, and telophase.
Considering a diploid (2n) cell with four (4) number of chromosomes.
Prophase- four duplicated chromosomes condense and pair up.
Metaphase- four chromosomes line up at the cell plate or equator in order to get separated.
Anaphase- the sister chromatids are pulled apart by the spindle microtubules
Telophase: the chromosomes recoil and organelles form at opposite poles of the cell.
At the end of cytokinesis, which is division of the cytoplasm, four chromatids are present in each daughter cell. The chromatids becomes individual chromosomes that retain the diploid (2n) chromosome number of four.
Other hawks, eagles, owls can prey on them. The Goshawk is well known for removing any competitors from it's territory, even larger species. Large owls sometimes take hawks that are roosting at night or even when they are incubating eggs. Any type of cat, or dog, or marten, indeed any carnivorous mammal.
