Answer:
When calcium concentration increases during depolarization, it shifts the conformation of troponin and tropomyosin, and actin is able to associate with myosin. As calcium is taken up again by the sarcoplasmic reticulum the muscle cell relaxes.
In telophase, the cell is nearly done dividing, and it starts to re-establish its normal structures as cytokinesis (division of the cell contents) takes place. The mitotic spindle is broken down into its building blocks. Two new nuclei form, one for each set of chromosomes.

The large Intestine is the organ that absorbs excess water from undigested food prior to its release from the body as a solid food.
Answer:
TRUE
Explanation:
Phasic receptors are sensory receptors that are fast acting in detecting changes in the strength of a particular stimulus or signal to the brain. They are fast adapting receptor cells that detect changes in the strength of a stimulus. Because of this fast adapting ability, they cannot be used by the CNS in constant signalling of stimulus. A different receptor called Tonic receptors are used by the brain for constant signalling because they are slow reacting cells are they continue to transmit signals to the CNS along as the stimulus remains and not to changes in the pressure or strength of the stimulus. Phasic receptors are so important in predicting the changes in the body fora given time and this helps to quantify how body can react to increase or release of a stimulus. because when stimulus is added it signals the brain for some time and it signals stops but when the stimulus is released, it also signals the brain detecting bodily deformations to various stimulus.
