To summarize: The nerve pathways involved in equilibrium. Concept introduction: The awareness and monitoring of the head position refer to equilibrium. The brain receives the sensory inputs sent by the sensory receptors. The sensory input from vestibular apparatus, visual sensory input, and the proprioceptor sensory input integrates with each other to balance the equilibrium. During static equilibrium, the utricle and saccule detect the stationary position of the head. For example, when one person is standing straight, the utricle and saccule inform the brain that the head is at an upright position. The utricle and saccule detect the linear acceleration of the head. In contrast, the semicircular ducts are responsible for detection of angular acceleration of the head.

Answer 1

Question

Definition Definition Rate of change of angular velocity. Angular acceleration indicates how fast the angular velocity changes over time. It is a vector quantity and has both magnitude and direction. Magnitude is represented by the length of the vector and direction is represented by the right-hand thumb rule. An angular acceleration vector will be always perpendicular to the plane of rotation. Angular acceleration is generally denoted by the Greek letter α and its SI unit is rad/s 2 .

After you feel comfortable with your counting method and identifying cells in the various stages of mitosis, use the four images below of whitefish blastula to count the cells in each stage until you reach 100 total cells, recording your data below in Data Table 1. (You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage. (Divide total of stage by overall total of 100 and then multiply by 100 to obtain percentage.) Data Table 1Stage Totals PercentInterphase Mitosis: Prophase Metaphase Anaphase Telophase Cytokinesis Totals 100 100% To find the length of time whitefish blastula cells spend in each stage, multiply the percent (recorded as a decimal, in other words take the percent number and divide by 100) by 24 hours. (Example: If percent is 20%, then Time in Hours = .2 * 24 = 4.8) Record your data in Data…
