What prevents the backflow of urine from the urinary bladder to the kidneys?

The urinary system is made up of the kidneys, bladder and ureters (tubes that connect the kidneys to the bladder). The kidneys act as filters removing extra fluid and waste from your blood to make urine. Urine passes from the kidneys into the ureters, which drain into the bladder. When the bladder is full, urine flows out of the body through a tube called the urethra. The ureters normally enter the bladder at a diagonal angle and have a special one-way valve system that prevents urine from flowing back up the ureters in the direction of the kidneys. If this system doesn’t work, urine can flow back towards the kidneys. This is called vesicoureteric reflux (also known as urinary reflux). Sometimes vesicoureteric reflux (VUR) can be associated with other 'plumbing' problems in the urinary tract and with small, damaged or malformed kidneys.

So I believe the answer is 1.

- Start with the P generation with the following genotypes (AA x aa). Based on classical Mendelian inheritance, how will a cross
nexus9112 [7]

Answer:

<em>The correct option is Although the F1 generation will all show the dominant trait, the offspring  will all be heterozygous and increase chances of future variation.</em>

Explanation:

The cross for the offsrings that will be produced by F1 generation is shown below:

         a          a

A      Aa       Aa

A      Aa        Aa

As we can see that all the offsprings in the F1 generation will have heterozygous genes but only the dominant trait will be seen in the phenotype of the F1 generation.

A cross between the F1 generation will give the following results:

         A          a

A      AA      Aa

a       Aa      aa

This cross shows that there will be increases genetic and phenotype variations in offsprings that will be produced by the F1 plants.
