arbon, as with many elements, can arrange its atoms into several different geometries, or "allotropes." In pure diamond, every carbon atom is covalently bonded to exactly 4 other carbon atoms in a very specific and energetically favorable geometry. The diamond cannot be broken or scratched unless many covalent bonds are broken, which is difficult to do. In another common allotrope, graphite, every carbon atom is covalently bonded to only 3 other carbon atoms, and the atoms are arranged in sheets that are not covalently bonded to each other. The sheets can be broken apart easily, ultimately meaning that graphite can be easily scratched. Coal is composed of particles of different allotropes of carbon, and some "amorphous carbon," which has no defined geometry in its atomic structure. Without a continuous network of covalent bonds, coal is easily scratched (i.e. it is not hard).
Think of blood as a gas/ fuel for the car ( your body). If there is no fuel, there's no movement (dead) so when the fuel tank is damaged the car won't function properly.
So if the heart becomes damaged, or weakened it would start making blood clots and damage the organs that need blood to function properly. The circulatory system wouldn't function properly and because other organs depend on the circulatory system it would cause a chain reaction, affecting other body systems. <span />
The types of evidence for evolution include
i) Changes in allele frequency over subsequent generations.
ii) When the population in question is examined it does not follow Hardy-Weiberg equilibrium.
iii) Signs of gene flow between populations.
iv) Presence of Sewall-Wright effects or genetic drift in the population.

Explanation:
Answer: Option C."hypernatremia"
Explanation:
Hypernatremia is defined as the a electrolyte problem in which sodium concentration rises to a value more than 145 mmol/L in serum.
The major symptoms of hypernatremia involves thirst, muscle twitching or spasms, and confusion.
Hypernatremia is a hyperosmolar condition caused by a decrease in total body water (TBW) against electrolyte content and several causes of hypernatremia includes intake of hypertonic fluid, salt poisoning in children, and inadequate intake of free water associated with total body sodium depletion et cetera.
Hence, the correct option is C.
