The answer is oropharynx.
The reason for this type of epithelium in this region of the respiratory tract is due to
its proximity to the esophagus. This
means that this region of the respiratory
tract is subject to abrasion by food
passing down the esophagus. This
epithelium is continuous with that of the esophagus.
The Bartholin's Glands, which are also known as the vestibular glands are a pair of pea size gland. The location of the Bartholin's gland is postrior to the vaginal orifice.
The main function of these Bartholin's gland is to secrete mucus and to lubricate the vaginal orifice. These gland is homologous to the bulbourethral glands present in the males.
<h3>Hence, the vaginal orifice is lubricated by secretions from the Bartholin's Glands.</h3>

Answer:
0
Explanation:
This question involves a single gene coding for wool color in sheeps. The allele for white wool (TT) is dominant over the allele for spotted wool (tt). This means that a sheep with an heterozygous genotype (Tt) will be white-wooled.
In this cross, 10 purebred white wool sheep (TT) are crossed with 10 spotted wool sheep (tt). This will give rise to all offsprings with heterozygous genotype: Tt (see attached image for punnet square). Since, white wool (T) is dominant, all the offsprings will have a white wool and none i.e. 0 will have a spotted wool.
<span>Depletion of the ozone layer. Choloroflourocarbon (CFCS) are dangerous because of their destructive reaction with Ozone particles, which provide the Earth with a protective layer or shield against UV radiation. Depletion of the ozone layer begins when when CFC gets into the stratosphere. Sunlight breaks up cfcs releasing Chlorine Atom. Chlorine atoms in turn react with Ozone, starting a chemical cycle that destroys the ozone layer in that area. Once the ozone layer is depleted, there's nothing holding back the harmful UVB wavelengths of ultraviolet light (UV light) from passing through the Earth's atmosphere causing havoc on plants and animals.</span>
