Is SUV rationing a better way to conserve fossil fuels than shutting down oil and coal burning electric plants?

We Answered:

Yes. While artificially rationing SUVs isn't real smart, it's brilliant compared to shutting down electric plants.

With water shortages all over Australia why can't the states be forced to put in desalination plants,?

We Answered:

Who is going to pay for this? There has to be be a balance of fresh and salted water on the planet. Changing the balance can change the magnetic poles

True or False?? Photorespiration is an alternate way to fix carbon in plants that must conserve water?

We Answered:

PHOTORESPIRATIO IS THE UPTAKE OF OXYGEN AND PRODUCTIO OF CARBONDIOXIDE IN THE PRESENCE OF LIGHT BY PHOTO SYNTHESISNG TISSUES.IT DOES NOT HELP PLANTS TO CONSERVE WATER

Is photorespiration an alternate way to fix carbon in plants that must conserve water?

We Answered:

yes it is.
Photorespiration occurs when the CO2 levels inside a leaf become low. This happens on hot dry days when a plant is forced to close its stomata to prevent excess water loss. If the plant continues to attempt to fix CO2 when its stomata are closed, the CO2 will get used up and the O2 ratio in the leaf will increase relative to CO2 concentrations.

When the CO2 levels inside the leaf drop to around 50 ppm, Rubisco starts to combine O2 with RuBP instead of CO2.

The net result of this is that instead of producing 2 3C PGA molecules, only one molecule of PGA is produced and a toxic 2C molecule called phosphoglycolateis produced.
