Answer:
Option D
Explanation:
Options for the question
A) The Y chromosome is slower to mature than the X chromosome.
B) Replication of the X chromosome occurs more often in males.
C) Male hormones cause the expression of X-linked traits.
D) Males only have one copy of the X chromosome
Given-
Duchenne muscular dystrophy (DMD) is an X-linked recessive condition which means it will occur in male even if they have one diseased X gene. While females will have this disease only when they have two diseased X gene
Hence, in most of the cases women with only one diseased X chromosome act as carrier and show normal traits.
Let us assume X is normal gene and X' is the diseased gene then
Genotype of normal father will be - XY
Genotype of carrier mother will be - XX'
Now if these two mates, following offspring will be produced
XY * XX'
XX, XX', XY, X'Y
So the male with X'Y will have DMD
Hence, option D is correct

Explanation:
Answer: d) Federal bureaucrats delay implementation of the new law after it has passed Congress.
Explanation:
The pluralist democracy can be described as a kind of political system where there is more than one center of power. This means that the power is allocated in different hands and authorities. This allows the freedom of association. It may exists without democracy.
The congress has passed the law under its authority but it has to be passed or implemented by the federal bureaucrats as the power is allocated to the different centers under the pluralist model of democracy.
