Patient A is suffering from anemia, due to underproduction of hemoglobin
Explanation:
Patient A’s blood cell count:
Hemoglobin: 5g/dL
RBC: 4.6 x 106 cells/ml
WBC: 15,000 cells/ml
Platelets: 250,000
Results inferred from the count: Low hemoglobin, low normal RBC, high WBC, normal platelets count
Hemophilia is an inherited blood clotting disorder, where due to excessive bleeding, blood hemoglobin, RBC, and platelets can go lower. The low hemoglobin is due excessive loss of blood and not due to underproduction of hemoglobin. Moreover, patient A’s platelet count is normal. Hence, hemophilia can be ruled out.
Since the hemoglobin and RBC count is low, it clearly indicates low production of these blood cell components, leading to anemia. However, the increase in WBC leads can be due any other underlying medical conditions like infections, hemolytic anemia, leukemia etc.
The correct answer is: B. The water before filtration is a mixture because the particles could be physically separated.
A mixture is composed of more than one individual substances that can be separated using different methods (depending on the type of mixture). Methods for the separation include filtration, evaporation, distillation and chromatography. The dirt stays behind in the filter paper (it becomes the residue) andthe water passes through the filter paper (it becomes the filtrate).
Answer:
X-linked/Sex-linked recessive inheritance
Explanation:
<em>The most likely mode of inheritance of the trait is an X-linked recessive inheritance.</em>
The sex chromosome of a male is XY while that of a female is XX. The Y chromosome is hypothesized not to carry any allele ordinarily. Hence, a male child only needs to inherit one affected allele to become affected for recessive X-linked traits.
During gamete formation, the sex chromosome of the male segregates into X and Y gametes while that of the female segregates into X and X gametes. During fertilization, the X gamete of the male is usually inherited by the female while one of the X gametes of the female is usually inherited by the male.
<u>Assuming a father is affected for an X-linked recessive trait, the affected X chromosome will be passed to a female child and such a child would be a carrier, rather than being affected since she requires the two X chromosomes to be affected in order to exhibit the trait. </u>
<u>The affected X chromosome is thus passed to her male child according to the law of inheritance of the sex chromosome. Hence, the grandson of the affected man inherits the trait through the daughter of the affected man.</u>
