Answer:
Covalent
Explanation:
A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms.
Answer:
The correct option is <u>C. Glucose and oxygen</u>
Explanation:
Cellular respiration can be described as a process in which cells convert glucose and oxygen into carbon dioxide and water, along with the release of energy molecules i.e ATP. Hence, glucose and oxygen are the reactants for this reaction whereas carbon dioxide and water are the products.
The process of cellular respiration is essential for energy and it takes places in the mitochondria of the cell. The reason why mitochondria are known to be the power house of a cell.
The pharynx would need to come first in order for C to be correct.
B is also incorrect. Air flows through the bronchioles, then the
alveoli, and finally into or out of the capillaries where gas exchange
can occur with cells.
A is the only option that correctly describes the path of air through the respiratory system in the correct sequence.
The complete flow of air would be:
Nose>pharynx>trachea>bronchi>bronchioles>alveoli>gas
exchange with cells and then back out.
I would say A because they both have shells
