Lipid bilayer model was proposed for its structure but it was modified and new structure is according to fluid mosaic model. Plasma membrane is selectively permible as it selects small molecules like lipid etc (composition is also of lipid and as solubility principle like dissolve like) so large and charged molecules like plasma and ion can't pass through it. Lipid are in form of layer so at the chain when ever other phosphate group attach the place conjugate molecule (phospholipid ) formed
Answer:
What are the 2 ways plants use energy?
Explanation:
This process uses solar energy to convert carbon dioxide and water into energy in the form of carbohydrates. It is a two-part process. First, the energy from solar radiation is trapped in the plant. Secondly, that energy is used to break down carbon dioxide and form glucose, the main energy molecule in plants.
Two objects that are similarly charged will repel, while two objects with opposite charges will attract. Moreover, a neutral object will attract either charges.
The conditions which describe the partial pressures of systemic cells under resting conditions are:
- Relatively constant partial pressure of gases
- PCO₂ of 45mm Hg, and
- PO₂ of 40mm Hg
<h3>What are systemic cells?</h3>
Systemic cells are cells of the body which receive oxygen from the capillaries during respiration and gaseous exchange.
The systemic cells receive oxygen-laden blood from the capillaries and transfer carbon dioxide into the blood capillaries.
The conditions which describe the partial pressures of gases of systemic cells under resting conditions are as follows:
- Relatively constant partial pressure of gases
- Partial pressure of carbon dioxide, PCO₂ of 45mm Hg, and
- Partial pressure of oxygen, PO₂ of 40mm Hg
In conclusion, the partial pressure of the gases in systemic cells under resting conditions are fairly constant.
