Answer:
The sound waves then travel toward a flexible, oval membrane at the end of the ear canal called the eardrum, or tympanic membrane.
Explanation:
The auricle (pinna) is the visible portion of the outer ear. It collects sound waves and channels them into the ear canal (external auditory meatus), where the sound is amplified.
Cystic fibrosis is a recessive condition; meaning if a
dominant condition takes over it will not be seen in the offspring. The man
genotype with cystic fibrosis can only be this: cc (when c is equal to the cystic fibrosis and C is equal to not
having one). The woman with no history of cystic fibrosis can possibly have
either of these two genotypes: Cc or CC.
To see their offspring’s possible genotype, we’ll use a
punnett square let’s start with Cc:
C c
c Cc cc
c Cc cc There
is a 50 % chance of the child having cystic fibrosis.
To see their offsprings possible genotype with CC:
C C
c Cc Cc
c Cc Cc There
is no chance that the child will have cystic fibrosis.
