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.

What is it called when two hormones cancel each other out or have opposite effects?
mina [271]

antagonism

When two hormones cancel each other out or have opposite effects it is called antagonism.

<h3>What is an example of antagonism?</h3>
  • Traditional examples of antagonistic hormones include insulin and glucagon.
  • In contrast to glucagon, which stimulates glycogenolysis, or the conversion of glycogen to glucose, insulin stimulates glycogenesis, or the conversion of glucose to glycogen.

<h3>What does the term "antagonistic hormones" mean?</h3>
  • Antagonistic hormones are those that work to bring body circumstances back from extremes to within acceptable bounds.
  • An illustration of how the endocrine system maintains homeostasis through the action of antagonistic hormones is the regulation of blood glucose concentration (by negative feedback).

<h3>How do antagonists to hormones function?</h3>
  • Infertility, endometriosis, and uterine fibroids are just a few of the diseases that gonadotropin releasing hormone (GnRH) antagonists are used to treat in women.
  • GnRH is a hormone released by the hypothalamus that is the target of GnRH antagonists, which stop it from functioning.
