<span>Cho finds a dinosaur tooth while on a school field trip. She has found an original-remains fossil . </span>Original remains can be

animal’s hard parts (teeth in this instance) after the soft parts have
decayed. This happens with dinosaur bones and teeth. <span>

Question: Impulses originating in the part of the brain called the medulla would most directly affect which body structure?
a. A leg muscle
b. A ligament
c. An arm bone
d. The heart
Answer:
d. The heart
Explanation:
The medulla oblongata contains a number of reflex centers for regulating vital body functions such as heartbeat, breathing, and vasoconstriction. The medulla contains several nuclei, a collection of neuronal cell bodies.
For example, impulses originated in the cardiovascular center regulates the rate and force of the heartbeat and the diameter of blood vessels. Impulses from the cardiovascular center flow along sympathetic and parasympathetic neurons. An increase in sympathetic stimulation from the cardiovascular center of medulla increases heart rate and contractility while a decrease in sympathetic stimulation decreases heart rate and contractility.
Un case if I were a carbon, then I would have originated from fossil fuels and left the ground, through the process of photosynthesis I would have entered the trees, I would have consumed by animals, even I would have released from some of the trees or plants that dies, I would have also released from animals by the process of decomposition after their demise, and animals can even breathe me in out by the process of respiration.
