What are stomata used for?
Releasing water vapor from plants. Guard cells use osmosis, the simple diffusion of water, to open and close letting certain amounts of water out.
Why do plants close the stomata during the heat of the day?
Stomata, also known as stoma, close in hot weather to retain water. Even though open stoma are necessary for photosynthesis, they can dry out a plant. About 90% of water absorbed by a plant is lost through open stoma. The guard cells close the entrance for protection against dehydration.
Would the stomata open or close if the CO2 concentration decrease?
Opening and closing of stomata is regulated by concentration of water in guard cells. When transpiration is required, water reaches the guard cells and they swell up. This opens the stomata's pore. When they are not required to be opened, water is not present in guard cells and they shrink causing stomata's pore to close.
Do grasshoppers have an open circulatory system?
a gasshopper has a open circulatory system ^.^
How does pH affect the rate of transpiration of a plant and why?
Stomata open in the presence of bases and close in the presence of acids. Therefore, the rate of transpiration is higher in bases due to that they are losing more water through their open stomata.
How do you get air out of hot water system?
Any propperly installed hot water heating system will have a high point vent. This consists of some sort of valve at the highest elevation of the entire system. Since air is lighter than water air will collect at the vent point. When the system is under pressure partially open this vent to allow air to escape. When water comes out the vent close it. This may have to be repeated several times to get all of the air out of the system.Open the hot water tap on the sink farthest from the water heater. Be sure the supply valve on the water heater is fully open.
Why must an electrical circuit be closed for energy to flow?
The electrical circuit is analogus to the water piping system. The word "close" means connection of a switch to get a complete circuit and to a water system you open the valve to let the water flows. Likewise if there is a connection the electrical energy flows. If "open" that means disconnected and for water piping system closing the valve to stop water flows. Therefore "close" for electrical ciruit means "open" for water piping system, and "open" for the former means "close" for the latter.
Is a car radiator a open system or close?

How to Keep Your Water Heater Clean?
By Andreina Urdaneta A clean water heater will heat and maintain water better and last longer. Once a year, flush your water heater, and in extreme hard water areas, at least twice a year. If you feel up to the challenge, here are some tips to help you in a basic cleaning. 1 Turn the water heater and the cold water supply to the water heater off. 2 Hook a high-quality garden hose to the drain valve, and place the other end in an area where hot water will not cause damage. 5. Open the drain valve. 6. Disconnect the cold water pipe on the top of the water heater. This step will let air into the water heater so it will drain. When the water heater is empty, close the drain. 8. Pour tile cleaner into the cold water, leave for a couple of hours and drain the detergent out of the tank. 10. Reconnect the cold water supply to the water heater. Open the cold water valve and let the water heater flush for a couple minutes. 12. Close the drain valve and open the hot water faucet nearest to the tank, and let the water heater fill. 13. When water starts to come out of that faucet, reopen the drain and let the water heater continue to rinse. After all the air is out of the water heater, turn it back on. Take care of your water heater, and it will take care of you. If you keep ignoring the task, your water heater may just leave you in the cold.
If you open hot water valve on the hot water heater what would happen?
The hot water valve should always be open, so the hot water can exit the heater into the system. If your actually meaning opening the drain valve on the bottom of theater, the water in the heater will drain, starting with the hot water stored there, and then the cold water that is entering the tank to replace it will simplt flow out the bottom before being heated. Dpending on where the heater is located will denepnd on how much of a mess the ensuing flood will be.
Should heater vent door be open are close when heater is on?
vent door will be open to what ever setting u set it on regardless of what temperature setting you are using
After close main water valve in front yard.. If I do air pressure test from a cold water tab.. could it detect any water leak on hot water pipe.?
yes, as long as the cold water inlet valve to your water heater is open.
How do you know if your hot water heater valve is open?
You know it by touching and feeling the pipes on the hot water side; if they are hot, there is water running through the pipes and obviously the heater valve is open on hot side.
