These are all part of the head or skull. The cavities of the
skull surround and protect the brain and sensory organs. There are five kinds
of cavities of the skull which are:
nasal cavity (paranasal sinuses is included here) - The
nasal septum split the respiratory system into two lateral halves, the nasal
cavity is also part of the respiratory system.
<span>cranial cavity - The large cranial cavity is split
into a posterior cranial fossa and an anterior cranial
fossa, a middle cranial fossa. Its function is to support the
brain.</span>
<span>
</span>
oral cavity - The oral, or buccal, cavity (commonly called
the mouth) is a cavity of the head rather than a cavity of the skull because of
its fleshy and muscular floor.
orbital cavity - supports and defends an eyeball and its linked
muscle, vessels, and nerves.
<span>middle ear cavity - From outer to inner, three small bones-malleus,
incus, and stapes are situated within the middle-ear cavities in the
petrous part of the temporal bones.</span>
In order to solve this problem we use these formula:
<span>p2 + 2pq + q2 = 1p + q = 1p = % dominant allele in the population
q = % recessive allele in the population
p2 = % homozygous dominant individuals
q2 = % homozygous recessive individuals
2pq = % heterozygous individualsFrom the given, we haveq2 = 21%Simply taking the square root,q = 4.58%</span>
Answer will be b for question
