Answer:
An ionic bond essentially donates an electron to the other atom participating in the bond, while electrons in a covalent bond are shared equally between the atoms. Ionic bonds form between a metal and a nonmetal. Covalent bonds form between two nonmetals

Answer:
Consumers must consume other organisms to get the food that they need and are known as Heterotrophs as they cannot make their own glucose. These consumers eat producers (plants). Herbivores are considered as first order consumers. These consumers eat consumers and producers (animals and plants).
Answer:
The correct answer is;
5. They were packaged at a higher pressure on the ground, thus causing the gas inside the packages to expand in the sky where the jet is at a lower pressure.
Explanation:
According to Boyle's law, the pressure of a given mass of gas is inversely proportional to it volume at constant temperature
P₁·V₁ = P₂·V₂
At the factories, the peanuts are packaged at atmospheric conditions whereby P₁ = 1 atm, however, the pressure of the air in the atmosphere decreases with altitude as such the pressure in the airplane jet is about a fraction of hat on the ground by about a factor of 0.7.
Therefore P₂ = 0.7 atm and we have
V₂ = P₁·V₁/P₂ = 1 atm×V₁/0.7 atm = 1.43·V₁
The volume increases at high altitudes
