Answer:
Density is nearly 3 cabs per hectare
Explanation:
Given -
There are three three intertidal regions.
Area of each intertidal region is 
hectares.
Number of crab in the intertidal regions are as follows -
Intertidal region I - 7
Intertidal region I - 2
Intertidal region I - 6
Sum of crabs in all three regions is equal to
Total area of all three intertidal regions is equal to
hectares
Now density per hectare is equal to total population of crab divided by total area of all the three intertidal regions
Density 
Density is nearly 3 cabs per hectare
When we breathe in, oxygen enters our lungs and enters small sacs in our lungs called the alveoli. In the alveoli, the oxygen diffuses INTO the bloodstream through small blood vessels, called capillaries, that surround these alveoli. The oxygen is now in our bloodstream instead of our lungs and is used in cell respiration etc.
Oppositely, carbon dioxide is diffused FROM the bloodstream TO the alveoli, also through these capillaries. The carbon dioxide is now in the lungs instead of the bloodstream and when you breathe out, the carbon dioxide is breathed out out of your lungs.
Hope this helped, even if it helped a tiny bit. :)
It prevents the formation of ATP and NADPH, which are needed by the light-independent reactions to make sugars. Thus, the correct option is D.
The herbicide atrazine binds to the D1 protein and prevents plastoquinone from binding. By preventing plastoquinone from binding, the photosynthetic transport of electron is disrupted, putting the generation of ATP and NADPH in the chloroplast at risk.
<h3>
What are herbicide?</h3>
Herbicides are chemicals that are used to control or manage unwanted vegetation. Herbicides are most commonly used in row-crop farming, where they are treated before or during planting to increase crop productivity while reducing other vegetation.
This results in the plant's inability to fix carbon dioxide and provide the nutrients it needs to survive. A halt in electron transmission causes oxidative stress and the generation of radicals, which leads to rapid cellular death.

Answer:
A
Explanation:
its the only that is true.
Lack of water would have an impact on the level of glucose produced hence decreasing the energy level that will finally be produced.
