Summary Introduction
To determine:
The hypothesis which was formulated by Alexander Fleming from his observations he made.
Given:
Several years before Alexander Fleming discovered penicillin, he made another exciting discovery. Fleming had a bad cold but kept working in his lab. He decided to put some of his nasal mucus in a petri dish of bacteria to see what would happen. Fleming observed that, over time, the mucus-covered area of the petri dish became clear of bacteria.
Introduction:
The human body has a well-developed immune system to resists against a wide variety of pathogens. The immune system is of two categories that include the innate immunity and the adaptive (acquired) immunity. The innate immunity consists of four different types of barriers. Secretions of antibacterial and antiviral proteins are classified in the group of physiological barriers.

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. All are in bottles of 100 tablets.How many total mg are needed for the patient and how many tablets of each would be needed to provide each dose?How many bottles of each would be needed to have available if this patient were to be on this drug regimen for 5 days?
The patient needs a solution of 2.5% dextrose in Lactated Ringer’s solution to run at 75 ml/hr for at least the next 12hours. LRS comes in fluid bags of 500 ml, 1 Liter, 3 Liters and 5 Liters. How can a 2.5% solution be made by adding50% dextrose to the LRS?

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).
