Answer:
See the answer below
Explanation:
Oxygen gas is produced during photosynthesis by photolysis of water in the chloroplasts of algae and green plants and in the thylakoid of cyanobacteria. The chlorophyll of photosystem II absorbs light energy which leads to the excitation and knocking out of an electron within the photosystem.
The energy released as a result of returning the electrons to the ground state in an acceptor molecule is used in splitting water molecules into hydrogen and oxygen. The electron released from the splitting of water replaces the one knocked out from the photosystem II while oxygen atoms from two water molecules combine to form diatomic oxygen which is later released as oxygen gas.
The whole process of photolysis of water and the release of oxygen gas happens during the light-dependent reaction of photosynthesis.
Light dependent reactions require an actual source of light, and this is from the sun, for energy to carry out the first stage of photosynthesis. They need solar energy to split a water molecule in order to obtain electrons from hydrogen to be used in fueling photosynthesis.
Light independent reactions do not require a light source for energy but rather they use energy that was created by the light dependent reactions to complete the process of photosynthesis in which different carbohydrates for the plant are made.
Answer:
Both of the regular intravenous solutions administered in medicine, normal saline and lactated Ringer’s solution, are isotonic. Why is this important?
Explanation:
<em>Because the isotonic saline solution</em> has a sodium concentration similar to that of blood.
ISOTONIC SOLUTIONS: <em>The osmolarity of the isotonic fluid approximates the osmolarity of serum plasma. </em>Isotonic fluids are used to hydrate the intravascular compartment in situations of significant fluid loss, such as dehydration, bleeding, etc.
Answer:
Mitosis takes about 2 hours to complete :3
Most cells would be viewed in interphase because it's the most important part of the stage where G1, S, and G2 phase are there too :3
