zimovet [89]
Based on the assessment of the newborn, it can be inferred that the newborn was fed with formula milk. Also, the baby demonstrates gastrointestinal functioning. Newborns experience a change in stool color and odor in the days after they were born. This indicates proper gastrointestinal functioning. The yellow color of the stool is due to the breakdown of bilirubin.

In humans, hemophilia is caused by a recessive allele on the X chromosome. Suppose a man with hemophilia has children with a hea
Virty [35]

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.

a_sh-v [17]

Answer:

d. a system that enhances the destruction of bacteria through the activation of mast cells, lymphocytes, and phagocytes

Explanation:

Mast cells are white blood cells (i.e., lymphocytes) that form part of the immune system. These cells form part of the first line of defense against pathogenic organisms. Some of the most important phagocytic cells that function to protect the body by ingesting pathogenic agents (e.g., harmful bacteria) include mast cells, monocytes, neutrophils, macrophages and dendritic cells. In this regard, it is important to highlight that mast cells are similar to basophil granulocytes (another type of lymphocyte), and they are derived from hematopoietic stem cells.
