Answer:
a. suprachiasmatic nucleus.
Explanation:
The circadian rhythm is an internal process that regulates daily cycle (sleep/wake conditions through the 24 hours). This process is performed by circadian clock which is located in hypothalamus, in the suprachiasmatic nucleus. It has been shown that when the suprachiasmatic nucleus is destroyed, regular sleep–wake rhythm is lost.
The suprachiasmatic nucleus sends information to the pineal gland, which secretes hormone melatonin (regulator of sleep–wake cycle).
this is a region in which cold air clashes with warm air. While there does tend to be a strong temperature gradient along fronts in the plains this explanation only touches the surface to why tornadoes are common in the plains.
A tornado requires a parent thunderstorm. Thus, an environment conducive to tornadoes must also be conducive to thunderstorms. Thunderstorms are much more common in certain locations. Thunderstorms are not nearly as common to the west of the plains as they are across the plains and to the east of the plains. The Gulf coast region has the most thunderstorms.
Water is one of the fundamental elements.
To solve this you would just divide 720 by 4 so it would take 180 years. Hope this helps!
<span>The appropriate response is cytoplasm. In eukaryotic cells, the cytoplasm is that piece of the cell between the cell film and the atomic envelope. It is the jam like substance in a cell that contains the cytosol, organelles, and incorporations, yet excluding the core.</span>
