Answer: True
Explanation:
Earth's south pole and the magnetic south are not the sole cause but an important element to why Earth is a magnet. "The south magnetic pole is the point on Earth's Southern Hemisphere where the geomagnetic field lines are directed vertically upwards. The Geomagnetic South Pole, a related point, is the south pole of an ideal dipole model of the Earth's magnetic field that most closely fits the Earth's actual magnetic field."
Answer:
The correct option is B) a pattern of biological functioning that occurs on a 24-hour cycle.
Explanation:
Biological rhythm is defined as the regular variation of an organic function related to the course of time, circadian biological phenomena (around the day), are those with a period of approximately 24 hours.
Circadian rhythms are physical, mental and behavioral changes that follow a daily cycle (the biological rhythm), and that respond primarily to light and darkness in an organism's environment. This cycle close to 24 hours, allows to recognize the sleep-wake phenomena and their homeostatic action, in the systemic processes of every living being. The circadian system is composed of photoreceptors, pacemakers and efferent pathways that allow a regular functioning of the sleep and wakeful state.
Answer:
I'm not sure what is unclear but I can try to help...
Explanation:
So the group is the number at the top and is verticle. So H,Li,Na, and K share the same Group, 1.
The period is the number at the side and is horizontal. Soo H and He are Period 1.
Now using this information we can find the specifics of each element.
Chlorine, for example, is Group 17A and Period 3 because it matches those.
Let me know if you need further explanation :)
In geology, a graded bed is one characterized by a systematic change in grain or clast size from one side of the bed to the other. Most commonly this takes the form of normal grading, with coarser sediments at the base, which grade upward into progressively finer onesI just learned about this in our rocks and minerals unit for science,
