The three foremost forms of photosynthesis are C3, C4, and CAM (crassulacean acid metabolism)
C4 flowers are so-called because the primary manufactured from CO2 fixation is a C4 natural acid, oxaloacetate, shaped by way of the carboxylation of phosphoenolpyruvate (PEP) by way of PEP carboxylase. The oxaloacetate is converted to other C4 acids (malate or aspartate) and transferred to the packaging sheath.
Calvin cycle is the main pathway of carbon fixation in vegetation, algae, and cyanobacteria. The opportunity pathways of carbon fixation are the Reductive citric acid cycle in microorganisms. 3-hydroxypropionate cycle in bacteria and archaea.

<span>The atmosphere of Venus is mostly carbon dioxide, 96.5% by volume. Most of the remaining 3.5% is nitrogen. Early evidence pointed to the sulfuric acid content in theatmosphere, but we now know that that is a rather minor constituent of theatmosphere.
T</span>he atmosphere of Neptune consists mainly of hydrogen and helium, but about 2.5-3% of the atmosphere is methane. Like Uranus, clouds in Neptune's atmosphere<span> are composed of crystals of methane.</span>
The question is incomplete. The complete question is as follows:
Functions of astrocytes include all of the following, except
A) performing repairs in damaged neural tissue.
B) guiding neuron development.
C) functioning in action potential transmission.
D) maintaining the blood-brain barrier.
E) creating a three-dimensional framework for the CNS.
Answer:
Functioning in action potential transmission.
Explanation:
Astrocytes may be defined as the glial type star shaped cells present in the central nervous system. They envelope the synapse and can function with millions of neuron at a time.
Astrocytes are involved in the structural support in the brain and can repair the damaged and wear nerves tissue. Their main function is acting as blood brain barrier. The action potential transmission is mainly done by neurons and not by the astrocytes cells.
Thus, the correct answer is option (c).
Photosynthesis.. hope I helped (:
