You don’t HAVE to have it but it can improve your energy for a workout and help build muscle
Frequency describes the number of waves that pass a fixed place in a given amount of time.
<span>The repolarization of cardiac muscle is due to closure of calcium (Ca) channels and potassium (K) exiting the cell when additional voltage gated K channels open.
Due to these changes within the heart, repolarization has to happen. This process refers to returning the cardiac muscle to its resting state, and the opposite process is depolarization.

Water-soluble and lipid-soluble hormones that bind to target cells are secreted by endocrine glands.
The interaction between endocrine glands, target cells, water-soluble hormones, and lipid-soluble hormones is accurately described by the aforementioned sentence.
<h3>What functions and how does the endocrine system operate?</h3>
The level of hormones in your blood is regularly monitored by your endocrine system. In order to transmit the message, hormones send their messages by locking into the cells they intend to reach.
When your hormone levels increase, the pituitary gland signals other glands to stop manufacturing and releasing hormones. The pituitary gland has the ability to tell other glands to manufacture and release additional hormone when levels fall below a certain threshold.
Homeostasis is a process that functions similarly to your home's thermostat. Almost every physiological process is impacted by hormones, including:
- Metabolism
- Growth & development.
- Fertility & sexual function.
- Sleep.
- Blood pressure.

Answer is hypertonic.
The ability of an extracellular solution to make water move into or out of a cell by osmosis is known as its tonicity. Tonicity is concern for all living things, especially in in organisms lacking cell wall, <em>Paramecium</em> is one such protozoan. It has specialized structures called contractile vacuoles. A contractile vacuole collects excess water from the cell and release it out, keeping the cell from lysing as it takes on water from extracellular environment which hypotonic (a lower osmolarity than the cell’s cytoplasm) as compared to hypertonic environment inside <em>Paramecium</em>.
