Refer to the figure showing a pedigree of a family affected by an x-linked recessive disorder. A female in generation 3 isn't a

carrier of the disorder. How can this be?
A. Females receive X chromosomes from this fathers only, which are unaffected in this case.
B. Females don't have X chromosomes so aren't affected by gene disorders passed on the X chromosome.
C. Females receive an X chromosomes from each point parent, but in cases of recessive disorders, the muted chromosome isn't passed on to daughters.
D. Females receive an X chromosome from each parent. If a mother is a carrier of an X-linked recessive disorder, her daughters have 50 percent chance of receiving her normal X chromosome and a 50 percent chance of receiving her mutated X chromosome.

Answer:

D. Females receive an X chromosome from each parent. If a mother is a carrier of an X-linked recessive disorder, her daughters have 50 percent chance of receiving her normal X chromosome and a 50 percent chance of receiving her mutated X chromosome.

Explanation:

Females have XX chromosomes as allosomes. They receive one X chromosome from mother and one from father. The female in the III generation received both the healthy X chromosomes from each parent that is why she is not even carrier for the disease.

The modified diagram clearly indicating the genotyope of all the members of the pedigree tree is attached. In the diagram, healthy X chromosome is indicated by X while mutated X chromosome is indicated by doted X. It is clear from the diagram that this female of III generation has XX chromosomes.  

The cross for that particular female is shown as under:

                               Mother               Father

                                   ẊX      x             XY

                                  /     \                  /     \

                               ẊX     ẊY          XX    XY

XX are the allosomes of this female child.

How much Sr(OH)2 • 8 H2O (M = 265.76) is needed to prepare 250.0 ML of solution in which [OH]= 0.100M?
SVEN [57.7K]
Use the formula 
first step: 
Use the formula 
molarity= mole/liter
change ml to l
plug in data
 to get .1=mole/.25 or .1M*.25liter
which =.025 moles
then divide .025 moles by two because there are two OH in Sr(OH)2 
then multiply that by 265.76 (the molar mass of water) 
.0125*265.76
which is 3.32grams this is your answer

Octane has a density of 0.703 g/ml. Calculate the mass of CO2(g) produced by burning one
STatiana [176]

The mass of CO₂ gas produced during the combustion of one gallon of octane is 8.21 kg.

The given parameters:

  • <em>Density of the octane, ρ = 0.703 g/ml</em>
  • <em>Volume of octane, v = 3.79 liters</em>

<em />

The mass of the octane burnt is calculated as follows;

m = \rho V\\\\m = 0.703 \ \frac{g}{ml} \times 3.79 \ L \ \frac{1000 \ ml}{L} \\\\m = 2,664.37 \ g

The combustion reaction of octane is given as;

2C_8H_{18} +  \ 25O_2 \ --> \ 16CO_2 \ + \ 18H_2O

From the reaction above:

228.46 g of octane -------------------> 704 g of  CO₂ gas

2,664.37 of octane --------------------> ? of CO₂ gas

= \frac{2,664.37 \times 704}{228.46} \\\\= 8,210.3 \ g\\\\= 8.21 \ kg

Thus, the mass of CO₂ gas produced during the combustion of one gallon of octane is 8.21 kg.
