Expt. No.
SashulF [63]

Answer:

The process of the formation of Urine starts when the blood enters the kidney and is filtered by the nephrons to separate the water from the larger elements that compound it like blood cells and proteins. Then, they go to the blood, and the elements that passed the filtration membrane go to the renal tubule to be moved to the bladder or be reabsorbed in case they are necessary for the body.

Explanation:

The Urine creation process starts with the blood entering the nephron in the kidneys. Then it is filtrated blocking blood cells and large proteins, making only water and smaller elements pass the filtration membrane. Then, cells and proteins, as well as the elements that couldn't pass the filtration membrane, go back to the bloodstream. While the elements that passed the filtration membrane go to the nephron to enter the renal tubule. In this tube some of the components that can still be used by the body are reabsorbed, the rest continues its journey to the bladder.

Alex Ar [27]

Answer:

<h2>Alice's daughter Alix =X X*   </h2><h2>George V= XY </h2><h2>Progeny  are;</h2><h2>XX, XY, X*X, X*Y </h2><h2>50 % males would be  infected </h2><h2>50% male normal</h2><h2>50% female normal, </h2><h2>50 female carrier. </h2>

Explanation:

Hemophilia is an inherited disease and it follows  an X-linked recessive pattern. The genes for hemophilia disease are located on the X chromosome. In males one mutated copy of the chromosome X  is sufficient to cause the condition, because male contain only one gene. Female  contain XX chromosome, so both the chromosome must have mutated for causing this disease.

According to  study of  Queen Victoria (1891-1901) of England, Alice's daughter Alix was X linked carrier and George V was normal male,

so if they got married, their children would be  

parents genotype  X X*   XY

progeny  

XX, XY, X*X, X*Y

50% males would be  infected

50% male normal

50% female normal,

50 female carrier.
