It is like a animal migrating because it is like hibernating because it doesn't get any food or water in winter.
Insulin is a hormone made by the pancreas that allows your body to use. After you eat food and your blood sugar level rises, cells in your pancreas (known as beta cells) are signaled to release insulin into your bloodstream. Insulin then attaches to and signals cells to absorb sugar from the bloodstream.
The cell requires a barrier between itself and its environment.
Answer:
The answer is 50
Explanation:
Hemophilia is a X-linked disease. That means the recesive allele which causes the disease is not in Y chromosome, but only in X chromosome. If we denote:
X⁺ : dominant allele
X⁻: recesive allele
Then, in a woman there are three posibilities:
X⁺X⁻: is a carrier woman (without hemophilia)
X⁺X⁺: healthy woman
X⁻X⁻: woman with hemophilia
But in a man there are two posibilities:
X⁺Y: healthy man
X⁻Y: man with hemophilia
A man with hemophilia is X⁻Y, and a healthy woman whose mother had hemophilia is a carrier woman (X⁺X⁻). If they have a child, there are 4 posibilities, and each one has 1/4 of occurrence probability:
X⁻Y x X⁺X⁻ = X⁻X⁺, X⁻X⁻, X⁺Y, YX⁻
Posibilities with hemophilia are X⁻X⁻ and YX⁻ (1/4 + 1/4= 1/2= 0.5= 50%)
In each filial, there is a 50 percent of probability of having a child (man or woman) with hemophilia.
