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.
Answer: D.
Explanation: Females have XX chromosomes while males have XY

The density would be the same for the whole bar as well as one half of the bar. Density is a identity I believe, by this I mean that it stays the same no matter how little or how much of the same substance you have. Since density = mass / volume, half the bar has half of the weight as well as half of the volume of the whole bar, making the density the same.
For example, a block weighs 10 grams and has a volume of 5 ml. the density would be d = 10/5 or, d = 2g/ml
Half of the block weighs 5 grams and has a volume of 2.5 ml. The density is d = 5/2.5, or, d = 2 g/ml.
See, although there are different amounts of the same substance, their density is the same.

Answer:
Explanation:
Hey,
so here the student is saying that the given mass is of one atom. But when we usually talk about amu it is the unified atomic mass so mass of all the atoms present.
So that's why he is wrong.
Also the definitions states,
The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope.
Answer:
See below.
Explanation:
121.76 amu is the Relative Atomic Mass of Antimony (the average mass of the different isotopes). . The element exists as a mixture of isotopes , the main one being SB121 which has a mass of 121.
