<span>Hypospadias is a birth defect where the
opening of the urethra, instead of at the tip, is on the underside of the penis.
The urethra is where urine drains from your bladder and then exits your body.
The repair for hypospadias is most often done when boys are between 6 months to
2 years old. Boys born with this are not told to be circumcised at birth.</span>
Answer:
No I do not think that all of the cells in an animal are the same. All of the cells complete different things. For example, Mitochondria cells break down sugars and other compounds into celluar energy, while the skin cells are busy producing Keratin. This shows that no two cells are exactly the same.
Hope this helps!

Answer:
C. The songs will become more similar to each other.
Explanation:
To answer this question, first, you need to remember that both populations belong to the same species, so they can mate because there is no reproductive barrier. The only limiting physical factor impeding individuals of both groups to cross was the piece of land before the land got wetter. So once populations got together, individuals can easily mate.
One population´s males exhibit a courtship song that slightly differs from the one of the other group. This difference has a genetic basis. But females hardly notice the difference. All of them prefer loud frogs to quieter frogs, independently of the population to which they belong.
So when the two populations get together, individuals get mixed. Females do not recognize males of their group, and during the breeding season, all females will mate the most with louder males of any of the population. So females from population A might mate with males from population B, and females from population B might mate with males from population A. So after mating season, there is also a genetic mixture between populations.
The new generations will carry elements of both genotypes. So males´ songs will be even more similar to each other. Songs will become more similar to each other because individuals of both populations are mixed and mated, and their genes intercrossed, producing new individuals with genes of both populations.
