Answer:
Ionic bonding is the complete transfer of valence electron(s) between atoms and is a type of chemical bond that generates two oppositely charged ions. By losing those electrons, these metals can achieve noble-gas configuration and satisfy the octet rule.

Answer:
Helps eliminate waste products such as urea, uric acid ammonia, and other products via urine.
It helps maintain the osmotic level of blood and plasma.
It helps maintain the electrolyte balance in the body.
And it also helps in the metabolism of those drugs that do not get metabolized in the liver.
Explanation:
<em>"The excretory system is a passive biological system that removes excess, unnecessary materials from the body fluids of an organism, so as to help maintain internal chemical homeostasis and prevent damage to the body. The dual function of excretory systems is the elimination of the waste products of metabolism and to drain the body of used up and broken down components in a liquid and gaseous state"</em>
Answer:
oxygen is reduced to form water.
Explanation:
Cellular respiration
It is the set of reactions in which the ac. Pyruvic produced by glycolysis is split into CO2 and H2O and 36 ATP are produced. In eukaryotic cells breathing is performed in the mitochondria. It occurs in two stages:
- PIRUVATE OXIDATION
- AC CYCLE TRICARBOXYL
The "problem" with fermentation is that, by using organic molecules as terminal electron acceptors and having to dispose of the resulting product (lactic acid / ethanol) as waste, the potential energy of these compounds is lost.
The alternative solution is to use some non-organic molecule that can accept electrons and thus become a reduced molecule. Oxygen is perfect for this, because after receiving the electrons it combines with two protons, thus becoming the perfect liquid residue for the environment: H2O.
