Which type of lipid is a major component of the cell membrane
Delicious77 [7]

Answer:

Phospholipids

Explanation:

Phospholipids are a particular kind of lipid (an oil) that forms a two-layered surface that surrounds and protects all living cells. The phosphates are essential to forming this bilayered structure. This membrane has a semipermeable function that selectively allows some elements and molecules to go in or out of the cell and thus helps maintain the cell in equilibrium.

The excretory system helps the respiratory system by
Leto [7]

Answer:

The excretory system helps the respiratory system by removing carbon dioxide that is produced during respiration (third option).

Explanation:

The lungs are in charge of the breathing process, being the main organ of the respiratory system. Each lung is considered an excretory organ —belonging to the excretory system— since it is capable of eliminating the carbon dioxide (CO₂) produced by the metabolism during expiration.

As a result of the gaseous exchange, the oxygen entering the lungs through the inhaled air passes into the blood, while the CO₂ is removed from the blood. This CO₂ is removed during expiration, which makes the lungs part of the excretory system.

The other options are not correct because:

  • <em>The excretory system does </em><u><em>not introduce more oxygen into the lungs</em></u><em>. </em>
  • <em>The </em><u><em>circulation of blood in and out of the lungs</em></u><em> is a function of the circulatory system. </em>
  • <u><em>Urine is not produced by breathing</em></u><em>.</em>
