Melting is the process where the atoms of a rigid solid Crystal lattice held by strong bonds, are broken down which increases the degree of locomotion of these atoms which characterises the liquid state.

The energy that breaks these bonds is heat energy ( latent heat of fusion ), hence temperature increases

Draw the phases of mitosis of a cell that contains four chromosomes as its diploid or 2n number

anastassius [24]

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.
