Summary Introduction
To analyze:
The influence of elevation on the Pika range, to check the hypothesis whether the pika range is shifting to higher elevation due to climate change or not, and the limitations in describing the patterns in nature in comparison with a controlled experiment.
Introduction:
The Pika are closely related to the rabbit, sharing short limbs, a fairly spherical body, a fur coat, and no external tail. However, Pika has shorter, rounded ears. The Himalayan mountains house the large-eared pika, which are generally known to be found at elevations of more than 6,000 meters or about 20,000 ft. The American pika is extremely sensitive to heat. They have poor fecundity and are susceptible to snowfall declines. They also have limited ability to disperse.

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).

When you sequence this enhancer you find several binding sites for the gap gene, Giant.
