Answer:
A the temperature increases.
Explanation: When the same amount of water is heated or cooled, its density changes. When the water is heated, it expands, increasing in volume.
Answer:
well using logic c would be the correct answer seeing how a is going the opposite direction, b is going both directions and d is going on a stright line even though the disk is moving counter clockwise.
Explanation:
i kind of explained it up there ^
Answer:
The spindle fibre is necessary to separate the sister chromatids into opposite sides of the cell.
Please find detailed explanation below
Explanation:
Mitosis is the cell division that produces two daughter cells that are genetically identical to the parent cell. Mitosis occurs in stages viz: prophase, metaphase, anaphase and telophase. The replicated chromosome, aligns at the centre of the cell in the METAPHASE stage and separates into opposite poles in the ANAPHASE stage.
This alignment (at the equator) and separation into opposite pole is possible with the aid of a structure called SPINDLE FIBRES. Spindle is a structure formed from microtubules, which attach to the kinetochores (located in the centromere) of each replicated chromosome to separate them from one another. Hence, the purpose of the spindle fibre during mitotic division is to separate the GENETIC MATERIAL of a parent cell into two daughter cells.
