Convection currents flow due to variations in the temperature and salinity in seawater, which both influence its density. Variations in density in different regions of the ocean will cause water to flow from less dense areas to more dense areas as water heats up and becomes less saline, producing a horizontal convection current. Vertical convection currents can arise as cooler, more saline water sinks, causing warmer, less saline water to rise.
Answer:
B) neurons have stable, relatively unchanging internal environments.
Explanation:
Rough endoplasmic reticulum (RER) is studded with ribosomes which in turn serve as the site for protein synthesis. A cell with an extensive network of rough endoplasmic reticulum has higher rates of protein synthesis. Mitochondria are the powerhouse of cells and serve as the site for aerobic cellular respiration. A large number of ATP molecules are produced in mitochondria. Therefore, a cell with relatively many mitochondria appears to have a higher demand for ATP and higher consumption of oxygen.
A cell with higher rates of consumption of ATP and protein synthesis should be functionally active. The charge across the membrane and the internal concentration of ions such as Na+, K+ of a neuron keep on changing during the conduction of nerve impulse. Therefore, the presence of many mitochondria and RER does not indicate that the neurons maintain relatively constant internal conditions.
Let me help you with this: the hypothalamus synthesizes some hormones that are released into blood vessels bound for another gland, synthesizes oxytocin and ADH and integrates nervous system and endocrine system. The posterior pituitary gland is an extension of the hypothalamus and releases oxytocin. And the anterior pituitary is regulated by hormones released into portal blood vessels, <span> synthesizes and releases TSH and </span><span> synthesizes and releases PRL. </span>
