- ATP supplies energy for cellular activities by releasing one of the phosphate group in its molecule
- Cellular activities in living organisms make use of ATP as source of energy
<h3>What is ATP?</h3>
ATP stands for Adenosine triphosphate and it is an energy carrier molecule in living cells of an organism.
The ATP molecule is made up of three components namely;
- Nitrogenous base
- 3 Phosphate groups
- Five carbon sugar
The ATP molecule gains one phosphate group when it stores energy and loses one when it releases energy.

Answer:
C) They are compressed during inhalation.
Explanation:
Birds breathe through rigid lungs that are located in the animal's thoracic region. The trachea of birds divides into bronchi that branch inside the lungs into very thin tubes called parabronchials or parabroncholes, which are irrigated by blood capillaries that allow gas exchange.
In birds there are no pulmonary alveoli (as in mammals), but air capillaries that depart from the parabroncholes. Oxygen gas passes from these capillaries to the blood capillaries, thus causing gas exchange.
In the lower portion of the bird's trachea, before branching the bronchi, we can find the syringe, a bag-like structure that has vocal cords responsible for the birds' scream and song. Most of the time, the sound emitted by birds serves to attract the mate, mark territory and prevent birds of the same species against some predator or other danger.
