Recently two follow-up studies of mortality among licensed pesticide applicators were published in the occupational health literature. One study from Florida found an overall standardized mortality ratio (SMR) of 1.80 and excess deaths due to leukemia, cancers of the brain, and lung cancer. A second study, based in Iowa, found an overall SMR of 1.20 and an elevated SMR for lung cancer only. The mortality statistics for the respective states were used for comparison purposes.
A. Is there reason for concern? Why or why not?
B. Why do you think that there was an elevated SMR for only one specific cause of death in Iowa? Knowing that applicators in both states use similar chemicals in their work, do you think that pesticide workers in Florida should be concerned that they may be at higher risk than their colleagues in Iowa?

When organisms become more similar by living in the same environment
Answer:
Convergent evolution is when two (or more) distantly related species independently evolve the same trait or gain a similar function. In math terms, convergence is when two things get really close to each other. For example, bats, birds, and insects are very distantly related but all have evolved the ability to fly.

cual es el proceso de la fotosintesis
Answer:
fotosintesis es el conjunto de reacciones gracias a las cuales las plantas verdes a partir de la energía luminosa transforman el agua y el anhidrido carbónico en oxígeno y sustancias orgánicas ricas en energía.
Sin el proceso de la fotosintesis no sería posible la presencia del oxigeno en la atmosfera. Son muchos los seres vivos que dependen del oxigeno que se libera durante la fotosintesis. Y no solo del oxigeno desprendido sino que la mayor parte de estructuras de los seres vivos para su desarrollo necesitan los productos orgánicos formados durante la fotosintesis junto a materia inorgánica del propio media ambiente. Por tanto puede decirse que la materia que forma a los seres vivos está formada por materia organica.

Create a mutant fly with any number of variations and mate it with a
wild-type fly. How many offspring are wild-type? What are the
phenotypes of the flies that are not wild-type?
Untamed type, a person who exhibits the typical phenotype, which is the phenotype typically present in a population of living things. Mutant, a person who deviates from the typical phenotype in some way.
What are the phenotypes of the flies that are not wild-type?The phenotypic of a species' normal form as it appears in nature is known as the wild type (WT). The wild type was initially thought to result from the “regular” standard allele at a location, as opposed to a non-standard, “mutant” allele.
Type wild, an individual with the typical phenotype, or the phenotype typically present in a population of living things in the wild. Mutant, a person, has a phenotype that is different from the typical phenotype.
Therefore, to characterize a gene in its natural, unaltered (unchanged), non-mutated form. Some cancer types have been linked to mutated (changed) versions of specific genes.

What is the ideal location for a radioactive waste storage facility?
A. in an area with a lot of people
B. far away from ground water
C. in an area that has a lot of earthquakes
D. in an area that already has a lot of background radiation
Answer:
B
Explanation:
It is really bad if the radio active waste spilled and got in the water or get on people. Putting it where other backround radiations are will worsen the area and may affect the waste. the earthquake area would put the facility indanger of coming down and spilling the waste all around it.
A population ecologist wished to determine the size of a population of white-footed deer mice, Peromyscus leucopus, in a 1-hectare field. Her first trapping yielded 80 mice, all of which were marked with a dab of purple hair dye on the back of the neck. Two weeks later, the trapping was repeated. This time 75 mice were trapped, out of which 48 of the mice were marked. Using the formula below, what is the population of mice in the field
Answer: 125
Explanation:
Population size is the number of individuals in a population. First, the trapping yielded 80 mice that were marked. Two weeks later, 75 mice were trapped and 48 of them had the mark.
The formula used for this question is:
N=mn/x
N= population size in the 1-hectare field. m= number of individuals marked and released the first time. n= number of individuals captured the second time. x= number of marked individuals that are recaptured.
The experiment consist on a randome collect sample of individuals which are then marked and released. Next, take a sample again.
So, replacing the values we get:
N=(80)(75)/48
N=125 individuals.

Which of the following statements best explains the structure and importance of plasmids to prokaryotes?
Plasmids are circular, single-stranded RNA molecules that transfer Information from the prokaryotic chromosome to the ribosomes during protein synthesis.
B
Plasmids are circular, double-stranded DNA molecules that provide genes that may aid in survival of the prokaryotic cell.
с
Plasmids are single-stranded DNA molecules, which are replicated from the prokaryotic chromosome, that prevent viral reproduction within the prokaryotic cell.
D
Plasmids are double-stranded RNA molecules that are transmitted by conjugation that enable other prokaryotic cells
acquire useful genes.
Answer:
B Plasmids are circular, double-stranded DNA molecules that provide genes that may aid in survival of the prokaryotic cell.
Explanation:
Plasmids would be additional chromosomal, double stranded also it is covalently that are closed and circular DNA molecules. It possesses genes that represent some unique attributes to the prokaryotic cell like fertility factor, F plasmid, etc. It may existed as an independent entity that should be within the cell or may be they integrate within the host genome this we called as an episomal in nature
In addition to this, Plasmids plays a significant role in the gene transfer i.e. horizontal that should be within the prokaryotes and are widely used in the recombinant DNA technology like vectors
Therefore, the option b is correct
Plasmids are the extrachromosomal material present in prokaryotic cells that divides independently. They are circular and aids in the survival of prokaryotic organisms.
What are plasmids?Plasmids are the extra genetic material that is double-stranded and circular found along with the nucleoid in the cytoplasm of the prokaryotic cell. They are majorly used in the genetic engineering process.
They provide protection and antibiotic resistance in the prokaryotes like bacteria as they carry antibiotic degrading genes and enzymes. They are capable of producing enzymes that can degrade antibiotics by cleaving them.
Therefore, option B. plasmids are double-stranded molecules that confer protection to prokaryotic cells.
