<span>The correct option from the given options is: "Scientist have determined the composition of Earth's core by using radiometric dating to examine meteorites".
</span><span>To date materials the procedure of radiometric dating or
radioactive dating is used, for example, rocks or carbon, in which trace
radioactive impurities were specifically fused when they were framed. The
strategy looks at the abundance of a normally happening radioactive isotope
inside the material to the abundance of its decay items, which shape at a known
consistent rate of decay.</span>

Answer:
d. cerebellum.
Explanation:
The cerebellum, which is part of the hindbrain, is a small structure made of a covering of white cortex found under the hemispheres of the cerebral cortex. The cerebellum plays a major role in the control and coordination of all physical movements such as balance, control, etc, that has to deal with smooth and balanced activities of the muscle.
A damage to the cerebellum would most likely lead to impaired motor coordination, staggering, inability to judge distance or when to stop.
The correct answer is: D) secretin
Gastric secretion is highly regulated whether its secretion should be increased (when food is eaten) or decresed (as the stomach empties). Secretion is controlled by the nervous system and endocrine system that work together. There are three phases of gastric secretory control:
Cephalic-by the brain
Gastric-by the stomach itself
Intestinal- by the small intestine
All of three can work simultaneously.
Secretin is released by duodenal enteroendocrine cells and it stimulates the pancreas and gall bladder, but also suppresss gastric secretion and motility. Secretion of the secretin is stimulated by the chime and it is the part of intestinal phase.
