Answer:
Option A, They contain a thick tunica media
Explanation:
Artery consist of tunics which is made up of three distinct layers
a) The internal layer is tunica intima – made up of epithelial and connective tissue layers
b) The middle layer is tunica media - thickest layer in arteries and consists of layers of smooth muscle supported by connective tissue
c) The external layer is tunica externa - sheath of connective tissue composed primarily of collagenous fibers
Answer: Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins). RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule. Transcription ends in a process called termination.
Assuming Hardy-Weinberg equilbrium, we have
p + q = 1
where p = frequency of dominant allele and q = frequency of recessive allele. So
p = 1 - q = 1 - 0.04 = 0.96
Consequently we have
• p² = 0.9216 = frequency of hom ozygous domininant genotype
• pq = 0.0768 = frequency of heterozygous genotype
• q² = 0.0016 = frequency of hom ozygous recessive genotype
since
p² + 2pq + q² = 1

Answer:
Mixtures can be physically separated by using methods that use differences in physical properties to separate the components of the mixture, such as evaporation, distillation, filtration and chromatography.
