For assistance with my studies, what is the homologies of sclaes types between chondrichyans (placoid sclaes), actinopterygians (ganoid sclaes, teleost scales), aquatic sarcopterygians (cosmoid scales), and reptile (epidermal scales)?

1. Identify similarities and differences between the Hyponatremia caused deaths of Cynthia Lucero and Jennifer Strange. Be sure to include details regarding presentation of symptoms and the circumstances that led to their deaths. (50+ words minimum).
2. Identify methods to best restructure the "Hold your Wee for a Wii" contest that Jennifer Strange participated in to prevent future Hyponatremia deaths. Just not doing the contest will not be accepted.  (50+ words minimum).

In what circumstances would it be justifiable to compel vaccination against a newly emergent pathogen, e.g., an especially virulent coronavirus, through mandates and criminalization? Discuss ethical, health, & social issues.

Suppose you invented a drug that blocked the production of LH from the anterior pituitary.  

1.  How would this affect the menstrual cycle?

2. Would this drug be a good method for birth control? Why?

Most of these fatty acids increase blood cholesterol levels by raising LDL cholesterol

These fatty acids raise LDL cholesterol while reducing beneficial HDL cholesterol

These fatty acids generally lower LDL cholesterol and raise HDL cholesterol

These fatty acids will lower LDL cholesterol, but in some people, they may also cause a decrease in beneficial HDL cholesterol

Describe a spore forming bacterium stained with the endospore stain and magnified 1000X.

Describe the spore and vegetative cell and note the colors you would expect to see using the stains we performed. What would you expect the Gram reaction of this cell to be?

How does recombination impact genetic variation in future generations including crossing over and meiosis?

In what types of ecosystems would you find chemoautotrophs rather than photoautotrophs? What trophic level does each group occupy?

In the Lake Ontario ecosystem, how would you characterize the trophic positions of the opossum shrimp and sea lamprey?

Distinguish the source of energy utilized by chemoautotrophs versus photoautotrophs.

Japanese researchers examined mutant alleles of a gene that encodes an enzyme, liver-type arginase, in four patients. The normal protein catalyzes the breakdown of the amino acid arginine. In argininemia, lack of the enzyme causes progressive developmental disabilities, spastic limb movements, seizures and stunted growth.

The mRNA transcript for this gene codes for 322 amino acids, but the entire gene is 11.5 kilobases long, and is located on chromosome 6q. Argininemia affects both sexes and is inherited from carrier parents.

Patient A – homozygous for a G mutated to an A at DNA base 365 in the gene

Patient B – homozygous for a G to C mutation at base 703, which substitutes one amino acid for another.

Patient C – has patient A’s mutation and patient’s B mutation.  

Patient D – has patient’s A mutation in one allele, and the other allele is a deletion of a C at position 842.

The researchers evaluated the phenotype associated with each allele by producing the encoded proteins in E. coli cells. Patient A’s abnormal protein is too short. The other mutations yield proteins of normal length that are unstable or otherwise nonfunctional.

1. The mode of inheritance of argininemia is ___________________________________________

2. Patients _____ and ______ are heterozygous for the argininemia gene.

3. Patients ____ and _____have missense mutations for the argininemia gene.

4. Why is patient A’s liver-type arginase too short?

5. Human liver-type arginase can be produces in E. coli because: A) E. coli have livers B) The genetic code is universal C) The genetic code is triplet D) E. coli also uses arginine

6. The argininemia gene has enough bases beyond those in exons to encode ____________more amino acids.
