The DNA copies are moved to opposite ends of the cell.
Answer:B
Explanation:
In C3 plant fixation of carbon occurs rubisco the Calvin cycle enzyme that add CO2 to ribulose bisphosphate to produce a three carbon compound 3-phosphoglycerate.
C4 plants have an alternate mode of carbon fixation that forms a four-carbon compound as its first products. In C4 plants there are two distinct types of photosynthetic cells; bundle-sheath cells and mesophyll cells. The Calvin cycle is confined in the chloroplasts of the bundle-sheath cell.
In the first step of this mechanisms an enzyme present only in the mesophyll PEP carboxylase adds CO2 to PEP to form oxaloacetate a four-carbon products.
The four-carbon is exported to the bundle-shealth cells where it releases CO2, which is reassimilated into organic material by rubisco and the Calvin cycle. The same reaction regenerate pyruvate. ATP is used to convert pyruvate to PEP, allowing the reaction cycle to continue.
In C4 plants ATP is the price for concentrating CO2 in the bundle-shealth. C4 photosynthesis has higher ATP requirements than the C3 pathway.
Biodiversity increases as the number of populations grow, because a greater population generally means a more diverse one.
However, this is not always true, so I'm not sure what answer they're looking for.
Answer:
b+ svn+ and b svn
Explanation:
Linked genes may be defined as the genes that are present on the same chromosomes. These genes are physically close together and can be inherited as a single unit in the progeny.
The bent wings (b) and shaven bristles (svn) are completely linked means that they can inherit as a single unit in the progeny. The cross between bb svnsvn and b+b+ svn+svn+ leads to the gamete formation of the genotype b+ svn+ and b svn in their off spring.
Answer:
Plants Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.
