Answer:
#Mitral valves
There is a valve at the meeting point between each ureter and the bladder to prevent the backflow of urine into the kidneys.
Urinary reflux means that one (or both) of these valves is not working properly.
If you have urinary reflux, during urination the urine travels up the affected ureter to the kidney instead of flowing out of the body.
Urinary reflux most commonly occurs in babies and children.
In most cases, the valve will correct itself as a child grows and matures.
In severe cases, surgery may be needed to remodel the valve.
#Urine flows from each kidney through tubes called ureters and into the bladder. When the bladder is full, it squeezes and sends the urine out through the urethra. No urine should flow back into the ureter when the bladder is squeezing. Each ureter has a one-way valve where it enters the bladder that prevents urine from flowing back up the ureter.

Answer:
Air,water,land,these are the A-biotic factors of the environment and are associated with life in many ways and life is totally defendant on these A-biotic factors of the life
Explanation:
Life is basically dependent on two components the biotic (living things) and A-biotic (non living) components of life.Living component are inked to each other with food chain and the energy is transferred between the food chains and the energy is made by the producer with the help of a biotic factors associated with the life. By using A-boitic component the producers the primary component of the food chain make the food and is consumed by the consumers and then the same way the energy is transferred from on level to the next level and energy is consumed up to 10 percent in each level of the food chain.
Photosynthesis is performed in the chloroplasts.
