phosphate is the nutrient limiting primary production in a small lake in northern michigan. in which way could new phosphate be made available to the primary producers in this lake?
New phosphate can be made accessible to the lake's primary producers through the decomposition of deceased fish.
How new phosphate be made available through the decomposition of deceased fish?Animals can act as nutrient sources or sinks in ecosystems, and the nature of their function in this regard may be influenced by what happens to the nutrients in decaying corpses, which may contain resistant materials like bones.
The rates of regenerated phosphorus (P) from corpses rose with temperature and declined with fish size. Nearly all (99%) of the phosphorus (P) produced by the carcasses of gizzard shad was regenerated back into the water column during the course of the 20 years. At the ecosystem level, the dynamics of the carcass nutrients followed a seasonal pattern, with the carcass nutrient pool seeing a net reduction in the summer due to mineralization but a net increase in the winter. Young-of-year fish (YOY) had a significant impact on the dynamics of carcass production and remineralization for P due to the fact that the quantity of fish born varies much between years, YOY had high mortality rates, and YOY carcasses disintegrate quickly.
Therefore decomposition of deceased fish makes new phosphate available.

Uncontrolled UTP to CTP conversion raises cytidine and deoxycytidine nucleotide pools while lowering uridine and thymidine nucleotide pools.
The need for exogenous thymidine during growth is explained by the depletion of endogenous thymidine nucleotides. During the extension step, the use of dNTP produces single bases that are prepared to enter DNA and double it. The dNTP gives nucleotides to the "unzipped" strand using the template of a single side as the technique's goal is to manufacture fresh DNA. To maintain genomic integrity, intracellular deoxyribo nucleotide triphosphate (dNTP) pools must be closely maintained. Changes in dNTP pools are, in fact, linked to a rise in mutagenesis, genomic instability, and tumorigenesis.
The complete question is:
Why do mutant cells have unbalanced nucleotide pools and require thymidine in growth medium?
Uncontrolled conversion of UTP to CTP elevates pools of cytidine nucleotides, which is an allosteric inhibitor of rNDP reductase and thus the accumulation of cytidine nucleotides prevents the cell from synthezing all of the three remaining nucleotides including thymidine nucleotides, which is the most widespread in mammalian DNA.Uncontrolled conversion of UTP to CTP elevates pools of cytidine and deoxycytidine nucleotides, while pools of uridine and thymidine nucleotide pools are diminished. The depletion of endogenous thymidine nucleotides explains the growth requirement for exogenous thymidine.Uncontrolled conversion of UTP to CTP exhausts cells' pool of 5,10-methylene-THF which is also required for thymidine nucleotide synthesis. The depletion of endogenous 5,10-methylene-THF means that TTP and dTTP can no longer be synthesized and have to be supplied with.Uncontrolled conversion of UTP to CTP elevates pools of cytidine nucleotides leading to unbalanced pyrimidine nucleotide composition associated with toxic effects.

4. animal models of infection a.discuss at least three ideal attributes of an animal model b.what should the criteria be for a nonhuman animal model to be acceptable as a stand-infor humans? under what conditions would you favor allowing human volunteers to beused as guinea pigs?
Ideal attributes of an animal model include reproducibility, accuracy, and a low cost of maintenance.
What is attribute?
An attribute is a characteristic or quality that is given to a specific individual, group, or object. Your willingness to assist others, as evidenced by the moment you halted traffic so that the duck family might cross the street, may be your best quality.
The Latin verb attribuere, that also includes the prefix commercial, meaning "to," and tribuere, meaning "give or bestow," is the source of the English word attribute. To attribute is a verb that means to give credit, as in: I attribute my A on the test to all my diligent studying. In Greek and Roman mythology, an attribute, like Zeus' lightning bolt as well as Poseidon's trident, will frequently stand in for a character.
a. Ideal attributes of an animal model include reproducibility, accuracy, and a low cost of maintenance. Reproducibility means that the results of the experiment should be repeatable and reliable, and that the model should be able to be used many times. Accuracy means that the model should accurately reflect the effects of a pathogen in humans. A low cost of maintenance is important because animal models are expensive to maintain and operate.
b. Criteria for a nonhuman animal model to be acceptable as a stand-in for humans include similarity in anatomy, physiology, and pathophysiology to humans, as well as similar sensitivity to drugs and the pathogen being studied. Additionally, the animal should be able to be bred and maintained in captivity, and the results of the experiment should be reproducible.
Under what conditions would you favor allowing human volunteers to be used as guinea pigs? Human volunteers should only be used in research when it is absolutely necessary, and when the risks of the experiment can be minimized. Additionally, ethical considerations must be taken into account, and the volunteers should be fully informed of the risks and benefits of their participation.
