In photosystem ║, the chlorophyll molecules releases 2 energized electrons; the electrons are placed by 2 electrons from a water molecule,forms oxygen gas (o2) and 2 hydrogen ions.
Explanation:
Photosystem ║is the protein complex in the light dependent reactions of oxygenic reactions of photosynthesis. The energized ions are replaced by oxidizing water to form hydrogen ions and molecular oxygen.
During photosystem ║, light strikes a photosynthetic pigment, the absorbed energy bounces to the chlorophyll molecules in the reaction center, it releases two energized electrons, the electrons are placed by two electrons stripped from a water molecule, forming oxygen gas(02) and 2 hydrogen ions.
The energized electrons are transferred to plastoquinone and are used to reduce NADPH are used in non- cyclic electron flow.
Main Cellular wastes are CO2 and Ammonia
For waste removal of cells ; there are many organs and in this question they are A , C, G , F !!
A. Circulatory system : Transport all waste
C. Excretory system: Removes Urea, and other wastes .
G . Urinary bladder is under excretory system as it stores the waste
F. Respiratory system is one of important organs that transport waste out of body as CO2 !! CO2 is a cellular waste amd thus F is also right !!
If you have any doubt ; comment !!
Answer:
Getting rid of trees means they can't photosynthesis
Explanation:
Photosynthesis is the process that all plants and trees do, they take in the CO2 that we breathe out and they turn it into oxygen for us to breathe in. If deforestation (getting rid of many trees) happens, it means they can't photosynthesis meaning CO2 stays in the air!
Hope this helps!
While waiting for a signal to contract, a muscle cell membrane maintains a slightly higher positive charge on the outside only because sodium-potassium ATPase pumps are available to generate this difference.
Only because sodium-potassium ATPase pumps are available to provide this difference, a muscle cell membrane maintains a marginally higher positive charge on the outside while waiting for a signal to contract.
To produce an action potential, these sodium pumps can transfer sodium ions across a cell's membrane. The body's muscles can then contract as a result of electrical signals travelling through it.

Using the photosynthesis from the sun it can regenerate through the ground and up through the sky and make rain of flying butts
