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 atomic models represents the most reactive element?
A. Argon, because it has three energy levels with eight electrons in the third level.
B. Lithium, because it has two energy levels with one electron in the second level.
C. Aluminum, because it has five energy levels with two electrons in the third level.
D. Carbon, because it has two energy levels with four electrons in the second level.
The most reactive element is represented by the atomic model for lithium, which consists of two energy levels with an electron in the second level. So, the correct option is B.
What is Reactive element?A reactive element is one that forms chemical bonds with other elements to obtain a stable electron configuration. Reactive elements are chemically unstable. The amount of valence electrons in an element's highest energy level determines how reactive it is.
The element with the fewest number of energy levels and most reactive valence electrons in the above example is lithium, which has only two energy levels and one electron in the second level. Lithium in this state has one valence electron, which makes it very reactive and predisposed to form bonds with other elements filling its outermost shell.
Therefore, the correct option is B.

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.

The whole world is affected by pandemic.what could be the reasons for its spread and what can we do to prevent it.
Answer:
Reasons for the spreading of this illness is due to the fact that people are not wearing their masks, not covering their coughs and sneezing which spreads germs, and during this time coming in close contact with others. To help prevent the spread would be for us to wear masks because not only does it protect us it helps protects people from our germs. Washing hands and covering coughs and sneezes can also help tremendously as well as keeping distance between others. The sooner we all practices these basic things the quicker all of us can get back to our normal lives because almost we know almost everyone misses the normal.
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.

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.
