In this model of a molecule of ammonia, NH3, how many covalent bonds are represented?
Answers
Based on the given model of ammonia, three covalent bonds are represented.
• A bond, which is formed by sharing pair of electrons is known as the covalent bond. The covalent bonds result in the formation of giant structures or molecules.
• There are different ways of demonstrating small covalent molecules, that is, by structural formulae, dot and cross diagrams, and three-dimensional structures.
• The given diagram shows the three-dimensional structure of ammonia. In this, one atom of nitrogen is forming covalent bonds with three hydrogen atoms.
• The formation of covalent bonds takes place as a result of electron pairs sharing between the atoms to attain stability.
Thus, an ammonia molecule exhibits three covalent bonds.

Mitochondria are the most important because they released the energy stored in food
I hope that's help you !
Final answer:
Mitochondria are the organelles that provide a cell with energy through ATP production via cellular respiration.
Explanation:
The organelles that are most important in providing a cell with energy are the mitochondria.
Within the mitochondria, ATP (adenosine triphosphate) is produced, which is the energy currency of the cell.
By undergoing cellular respiration, mitochondria produce ATP through oxidative phosphorylation, generating energy for various cellular processes.
