Answer:
Cell cycle control is an example of a homeostatic mechanism that maintains proper cell function and health. While progressing through the phases of the cell cycle, a large variety of intracellular molecules provide stop and go signals to regulate movement forward to the next phase.

In waves because sound echoes. Waves are the only form of energy that can echo.
Answer:
Spindle fibers move homologous chromosomes to opposite sides is called <u>anaphase I.</u>
Explanation:
Anaphase I is a stage of meiosis (which is a cell division). During this stage, homologous chromosomes, dragged by the achromatic spindle fibers, are separated towards each pole of the cell.
The achromatic spindle is a set of microtubules, this structure is shaped like two cones joined by their bases. It consists of protein fibers that radiate from each pole. The contraction of these fibers is responsible for the movement of chromatids during anaphase.
At the end of anaphase I, there's a set of chromosomes at each opposite pole of the cell, one of each pair of homologous chromosomes, so the number of chromosomes has been halved.
Explanation:
Sound travels in the form of a wave. Waves are characterized by three basic quantities. They are frequency, speed, and amplitude. Two of the main characteristics of sound are pitch and loudness, which in turn are determined by the frequency and amplitude of the wave, respectively.
