Answer:
Cytokinesis
Explanation:
The cleavage furrow is a 'pinching' or invagination in the cell membrane that occurs before the cell cytoplasm splits in two to form two daughter cells.
This occurs towards the end of mitosis, during telophase. This means that cytokinesis will not be able to proceed properly. Cytokinesis is when the cytoplasm divides to form two new cells. Without the cleavage furrow, the cell is not divided in two, and the new daughter cells cannot form. Therefore, cytokinesis cannot proceed properly.
Various species of the flowering plant of the genus <em>Chrysanthemum </em>have 18, 36, 54, 72, and 90 chromosomes. The variation is likely due to polyploidy.
<h3>What is polyploidy?</h3>
Polyploidy can be defined as the number of complete sets of chromosomes in a given cell of an organism.
A diploid organism contains two complete sets of homo-logous chromosomes in its somatic cells.
Many organisms used polyploidy as an evolutionary strategy for adaptation to challenging environmental conditions.

Answer:
Scientists believe that fitness is not only the ability to have physical fitness but it also refers to the adaptations that make an organism survive in its environment.
According to biological studies, biologists believe that the ability of an organism to survive in a particular area and to pass on its characteristics to its offspring is fitness.
The health scientists define fitness as the ability of an individual to be physically fit and to move without pain.
The scientists which study psychology believe that fitness is the well functioning of a person;s body as well as his/her mind.
