Nails are made of iron because, iron is strong and sturdy; although nail rust when it undergoes oxidation when expose to water but it is not explosive.
Barium and phosphorus are not suitable for nail making because of their properties.

Cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy. Usually, this process uses oxygen, and is called aerobic respiration. It has four stages known as glycolysis, Link reaction, the Krebs cycle, and the electron transport chain. yup
Answer:
The correct answer is: 25 %
Explanation:
According to Mandel's law of inheritance, the dominant allele masks the expression of the recessive allele if present together. If a couple has 3 children with brown eyes. In a monohybrid cross, the ideal phenotypic ratio of the offsprings is 3: 1 or in other words, the dominant character chances to appear is 75% in phenotype.
So, by the law of dominance of monohybrid cross the chances of the fourth child to develop blue eyes is 25%.
Thus, the correct answer is : 25 %.
