Sedimentary rocks<span> are </span>formed<span> when </span>sediment<span> is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension. This </span>sediment<span> is often </span>formed<span> when weathering and erosion break down a </span>rock<span> into loose material in a source area.
That is how they are formed, now think of a way they are not formed. Hope this helps!</span>
About 30. thankyou and goodluck
No, that would be January.
Secondary succession generally takes place faster in comparison to primary succession as the substrate is already present. In the case of primary succession, there is no soil and it consumes much time to form.
Primary succession takes place in mainly lifeless regions, that is, the regions in which the soil does not possess the tendency of sustaining life as an outcome of various factors.
On the other hand, secondary succession takes place in the regions where a community that previously prevailed have been eradicated and is epitomized by smaller scale turbulence, which do not eradicate all the forms of life and nutrients from the environment.
Answer:
14 CO₂ will be released in the second turn of the cycle
Explanation:
<u>Complete question goes like this</u>, "<em>The CO2 produced in one round of the citric acid cycle does not originate in the acetyl carbons that entered that round. If acetyl-CoA is labeled with 14C at the carbonyl carbon, how many rounds of the cycle are required before 14CO2 is released?</em>"
<u>The answer to this is</u>;
- The labeled Acetyl of Acetyl-CoA becomes the terminal carbon (C4) of succinyl-CoA (which becomes succinate that is a symmetrical four carbon diprotic dicarboxylic acid from alpha-ketoglutarate).
- Succinate converts into fumarate. Fumarate converts into malate, and malate converts into oxaloacetate. Because succinate is symmetrical, the oxaloacetate can have the label at C1 or C4.
- When these condense with acetyl-CoA to begin the second round of the cycle, both of these carbons are discharged as CO2 during the isocitrate dehydrogenase and alpha-ketoglutarate dehydrogenase reactions (formation of alpha-ketoglutarate and succinyl-CoA respectively).
Hence, 14 CO₂ will be released in the second turn of the cycle.
