A root of a cotton plant must
overcome various potential forces such as gravitational forces that pulls water
downward, matric forces where there is an adhesion of water molecules from a soil and osmotic forces where attracting water in the presence of large amount of soluble salts in the mixture of soil.
If the soil were compacted by
a heavy vehicle, the matric forces would be mostly affected for compaction will
result to increase matric forces due to reduced size of pores of the soil
making it more difficult to draw water from a solid surface.
Answer:
The correct answer is -transfer fixed carbon dioxide to cells in which the Calvin cycle occurs
Explanation:
In C4 plants the light reaction and Calvin cycle occurs in two different cell that are mesophyll cell and bundle sheath cells. First, the CO₂ is fixed into 4- carbon oxaloacetate by an enzyme PEP carboxylase.
Then this oxaloacetate is converted into a simpler form called malate. Malate molecule then enters into bundle sheet cell and there it releases one molecule of CO₂. This CO₂ enters the Calvin cycle which results in the sugar formation with the help of enzyme rubisco.
Therefore by releasing of CO₂ molecule by malate in bundle sheet cells, it transfer fixed carbon for the Calvin cycle to occur.
When obtaining the health history from a client with retinal detachment, a nurse expects the client to report FOR SOME ISSUES RELATED TO EYE SUCH AS LIGHT FLASHES AND FLOATERS IN FRONT OF EYES.
Retinal detachment is a medical condition where the retina is pulled away from the blood vessels that supply blood and oxygen. If not treated timely, it can lead to permanent loss of eye sight.
