The respiration which is seen in plants and higher animals including humans take place in the presence of oxygen.
What is respiration?The process in which the cells of an organism obtain energy by the combination of oxygen and glucose and results in the release of carbon dioxide, water and ATP (energy) is defined as the respiration.
In respiration, the transfer of oxygen occurs from outside environment to cells within the tissues. It is a biological reaction which takes place inside the cells of living organisms. The energy molecule ATP ( Adenosine triphosphate) is created during this process.
The ATP molecule produced here by the breakdown of glucose is utilized by the cells to perform various activities. The first step in cellular respiration is glycolysis which occurs in cytoplasm.
The correct path of oxygen transfer is:
Nostrils → Nasal cavity → Pharynx → Trachea → Bronchi → Bronchiole → Alveoli

What is the influence of temperature on a chemical change?
Answer:
Increasing the temperature will cause chemical changes to occur faster. Decreasing the temperature, causes the particles to lose energy which causes them to move around less and slower. The less they move, the less collisions occur, and the less reactions occur between the chemicals = slower reaction rate.

Sodium is a metal (Na), what makes the Neutral atom of Sodium different
from the lonized atom of Sodium
A neutral atom has more protons than an ion
Neutral atoms have more neutrons than an ion of an tom
Neutral atoms have a charge while ions do not
Neutral atoms have the same amount of protons and electrons while an ion has
either gained or lost an electron
Answer:
D
Explanation:
An ion is created because an atom doesn't have a balanced number of protons and electrons. A positive ion is created by an atom losing an electron and a negative ion is created by an atom gaining an electron.

Answer:
C
Explanation:
a fish cant breath outside water
Mammals use their lungs to provide oxygen from the air, while fish spend time in the water; instead, fish developed gills because gills allow the fish to use the oxygen that is dissolved in the water, which is option c.
What is the significance of the gills in animals?Gills are important for fish and other aquatic animals as they are the primary respiratory organ in aquatic animals, helping them obtain oxygen from water and release carbon dioxide into the surrounding water. Gills in fish and other aquatic animals help them breathe underwater and maintain vital metabolic processes.
Hence, mammals use their lungs to provide oxygen from the air, while fish spend time in the water; instead, fish developed gills because gills allow the fish to use the oxygen that is dissolved in the water, which is option c.
