The answer is; C
It is caused by the recessive allele because the parents appear normal but are carriers of the disorder (meaning they are heterozygous for Pseudohypertrophic muscular dystrophy). Only when the offspring is heterogenous recessive do they display the disorder.
The disorder is also sex-linked because it tends to affect only boys. This means that the disorder is probably coded for by alleles in the Y- chromosome that determines the male sex.
Answer:
It will take 27 seconds for a cyclist to stop completely.
Explanation:
Initial velocity of the cyclist= u = 13.5 m/s
Acceleration of the driver = a = 
Final velocity of the cyclist = v = 0
Duration of time in which 13.5 m/s velocity is changed to 0 = t = ?
Using first equation of motion:
v = u + at
It will take 27 seconds for a cyclist to stop completely.
Answer:
B. Scientific theories are a culmination of many pieces of evidence.
Explanation:
Darwin’s observations of Galápagos finches support the theory of evolution. Molecular homology of genes, such as Hox genes, provides another type of support for how species evolve.
In science, this simply implies that scientific theories are a culmination of many pieces of evidence.
Answer:
Warm front Forms when a moist, warm air mass slides up and over a cold air mass. As the warm air mass rises, it condenses into a broad area of clouds.
Enzymes cut out the erroneous nucleotides and then attach the correct nucleotides with the complementary strand.
