Answer:
What Are the 3 Reasons Why Cells Divide?
•Repair of damaged tissue.•Growth of an organism.•Replace old and dying cells.What are the chromosome number in diploid and haploid cells?
•Humans have 46 chromosomes in each diploid cell. Among those, there are two séx-determining chromosomes, and 22 pairs of autosomal, or non-séx, chromosomes. The total number of chromosomes in diploid cells is described as 2n, which is twice the number of chromosomes in a haploid cell (n).What are the phases of mitosis?
•Mitosis is understood to involve five phases, based on the physical state of the chromosomes and spindle. These phases are prophase, prometaphase, metaphase, anaphase, and telophase.What are the phases of the cell cycle?
The cell cycle is composed of interphase (G₁, S, and G₂ phases), followed by the mitotic phase (mitosis and cytokinesis), and G₀ phase.Explanation:

Almost 225 soccer fields can fit in one square mile . Approximately how many could you have to yourself if you lived in a region containing 25 people per square mile ? Or 100 people per square mile ?
(a) The size of the soccer field you can have to yourself if you leave in a region containing 25 people per square mile is 9 fields.
(b) (a) The size of the soccer field you can have to yourself if you leave in a region containing 100 people per square mile is 2.25 fields.
Size of soccer field to yourself
The size of the soccer field you can have to yourself if you leave in the given regions is calculated as follows;
For 25 people per square mileSize per person = (225 field/mi²) / (25 persons/mi²)
Size per person = 9 field per person
For 100 people per square mileSize per person = (225)/100
