Introduction: The eye of a human is a specialized organ. It has the ability to process and receive visual details. The light is detected by the eye and converted into

Answer to Problem 1.1BGL
Pictorial representation:
Fig1: The parts of conjunctiva
Explanation of Solution
1. Conjunctival fold: The conjunctiva is the mucous membrane. The eyelids’ inner surface and eyeballs’ exposed surface are lined by the conjunctiva. The pocket is formed by the conjunctival fold that possesses contacts from moving toward the eyeball’s posterior part.
2. Palpebral conjunctiva: The palpebral conjunctiva is the portion of the conjunctiva. The interior of the eyelid is covered by the palpebral conjunctiva.
3. Bulbar conjunctiva: The bulbar conjunctiva is otherwise referred to as ocular conjunctiva and it is a portion of the conjunctiva. The bulbar conjunctiva does not cover the cornea. It covers the anterior portion of the white of the eye.
To label: The structures of the lacrimal apparatus in Figure 24.1 (b).

Answer to Problem 1.1BGL
Pictorial representation:
Fig1: The structures of the lacrimal apparatus
Explanation of Solution
A group of structure involved in draining and generating tears is referred to as the lacrimal apparatus.
4. Lacrimal gland: The lacrimal gland secretes and generates tears onto the surface of the eye. The fluid is released continuously by the lacrimal gland, which protects and cleanses the surface of the eyes.
5. Lacrimal canals: They are small channels found in every eyelid and it is also called as lacrimal canaliculi. The tear is drained into the enlarged lacrimal sac from the eyes by the lacrimal canals.
6. Lacrimal sac: The dilated oval upper end of the nasolacrimal duct is lacrimal sac. The lacrimal sac is also referred to as lachrymal sac.
7. Nasolacrimal duct: The nasolacrimal duct is otherwise known as the tear duct. The tear is received by the enlarged nasolacrimal duct from the lacrimal sac and the tears are drained into the nasal cavity.

- An 1100 pound equine patient was given 20 mg/kg sucralfate 3 times a day, 2.8 mg/kg famotidine twice a day, and 10mg/kg doxycycline twice a day. Sucralfate comes as a 1 gm tablet, famotidine as 20 mg tablets, and doxycycline as 100mg tablets.

However, a SNP in the position shown in gray (right) would prevent cleavage at this site by EcoRI One of the SNPs in B. rapa is found within the Park14 locus and can be detected by RFLP analysis. The CT polymorphism is found in the intron of the Bra013780 gene found on Chromosome 1. The Park14 allele with the "C" in the SNP has two EcoRI sites and thus is cleaved twice by EcoRI If there is a "T" in that SNP, one of the EcoRI sites is altered, so the Park14 allele with the T in the SNP has only one EcoRI site (Fig. 5-3).

When you sequence this enhancer you find several binding sites for the gap gene, Giant. To test how Giant interacts with eve, you decide to remove all of the Giant binding sites from the eve enhancer.
