Answer:
d. 6 molecules, 18 carbons total
Explanation:
In a Calvin cycle 3CO₂ is combines with 3 RUBP to form 6 molecules of glyceraldehyde-3-phosphate (G3P). One molecule of G3P has three fixed carbon atoms, Thus to make one molecule of six carbon glucose molecules will take two molecules of G3P. Therefore six turns of the Calvin cycle required to make one glucose.
So, as per question, 6 molecules of G3P will required 18 carbons.
Answer:
Both are type of natural selection and ultimately lead to selection of a set of phenotype over the entire available genotype spectrum.
Explanation:
Both the stabilizing selection and directional selection are two forms of natural selection
Also in both the selection process, a new population with a better fitment to the prevailing environmental and physical conditions evolves.
In stabilizing selection, an average phenotype is selected over extreme variation. However, by this process of selection the genetic variance of the population will decrease.
However in directional selection, phenotypes at one end of the existing variation are selected over the entire spectrum
Organisms with more genetic variation are more likely to survive because if something changes in their environments, then they have a larger possibility to survive the changes.
