In the cell, energy that drives endergonic reactions is often obtained from
IRISSAK [1]

Answer: B) energy released from exergonic reactions.  

Explanation:

Cell metabolism is the set of reactions that occur in the cellular environment to synthesize or degrade biomolecules to produce energy. Synthesis metabolism of biomolecules is known as anabolic (anabolism) and catabolic degradation (catabolism).

Endergonic reaction (product has more energy than reagents) and requires energy to occur. Anabolism occurs when the cell has sufficient energy or substrate. Catabolism, in turn, occurs in situations in which the body needs energy, such as between meals and fasting.

The reactions of anabolism and catabolism are opposite but occur in an articulated manner, allowing the maximization of available energy. Thus, while catabolism occurs spontaneously, an exergonic reaction with ATP production, anabolism is non-spontaneous, or endergonic, requiring energy to occur. In other words energy that drives endergonic reactions is often obtained from B) energy released from exergonic reactions.

List the events of inspiration beginning with stimulation of the phrenic nerves
Andru [333]
The events of inspiration begins with the;
Impulses are conducted on the phrenic nerve to muscle fibers in the diaphragm contracting them.
As the dome shaped diaphragm moves downward the thoracic cavity expands.
At the same time the external intercostal muscles may contract raising the ribs and expanding the thoracic cavity further.
The intra-alveolar pressure decreases 
Atmospheric pressure greater than intra-alveolar pressure forces the air into the respiratory tract through the air passages.
The lungs fill with air.

This type of bond results in the exchange of electrons?
MissTica
An ionic bond results in an exchange or transfer of electrons between the 2 different types of atoms, most likely the metal atom and nonmetal one.

For example the compound NaF is held together by electrostatic forces of positive and negative charges due to the transfer of electrons from the sodium to fluoride atom.
