The Champaign-Urbana area has long been suffering from the heinous pathogenic bacterium, Michiganious wolverinous, which causes

rabid wolverine fever. During 2019, the Champaign Public Health Department reported an incidence of 1000 cases of rabid wolverine fever. If the number of pre-existing cases carried over from 2018 to 2019 was 2000 cases, then the prevalence of rabid wolverine fever in 2020 was __________________.
a. 3000 cases

b. 4000 cases

c. 1000 cases

d. 0 cases

e. 2000 cases

Answer:

The correct answer is option a, that is, 3000 cases.

Explanation:

The measurement of all the individuals getting influenced by the disease at a specific time is known as the prevalence. On the other hand, the measurement of the number of novel individuals that came into contact with a disease during a specific time duration is known as the incidence.  

Based on the given question, the number of prevailing cases carried from 2018 to 2019 is 2000, and the new diseases recorded in the year 2019 is 1000 (incidence). Therefore, the prevalence of the disease in 2020 will be 3000 cases.

Answer:

the process that would make them go as dark or light would be because they and blend in better to no the eaten it is called "latrell Selection" so in the Beach mice would stay light because they look like sand but if they were dark they would be easy to see that is why they are not there same thing for the forest but the other way around

if the forest changed to more sandy it would let lighter mice live there to but the dark mice would still live because it is not all sand i like it would be equal amount of dark and light mice because they would both have there spot to hide and just as vulnerable if the switched spots

Mars had an orbital period of 1.88 years. In two or more complete sentences,explain how to calculate the average distance from m
Vanyuwa [196]
This is an interesting problem involving astronomy, in fact, simple physics.
Let r=distance of sun to mars, in metres

<span>Mars had an orbital period of 1.88 years.
=>
tangential velocity, v, of the planet, in m/s is
v=\frac{2\pi{r}}{T}
</span>=\frac{2\pi{r}}{1.88*365.25*86400} m/s, accounting for leap years
=3.371*10^{-8}\pi{r}   m/s

The centripetal force, Fc, generated is
Fc=\frac{mv^2}{r}   
        where m=mass of mars = 6.39*10^(24) kg
=\frac{mv^2}{r}
=\frac{6.39*10^{24}v^2}{r}
=7.26168*10^9\pi^2r

The gravitation pull from the sun, Fg, is given by
Fg=\frac{GMm}{r^2}
    where G=grav. const., =6.67408*10^(-11) m^3<span> kg^(</span>-1)<span> s^(</span>-2)
              M=mass of sun=1.989*10^(30) kg
=\frac{6.67408*10^{-11}1.989*10^{30}6.39*10^{24}}{r^2}
=\frac{8.4826*10^44}{r^2}

Since the radial distance is in equilibrium, the average distance, r can be found by equation Fc=Fg and solving for r:
Fc=Fg
=>
7.26168*10^9\pi^2r=\frac{8.4826*10^44}{r^2}
Solving for the real root:
r^3=\frac{8.48256*10^44}{7.26168*10^9*%pi^2}
=\frac{1.1681263*10^{35}}{\pi^2}
=2.279*10^11 m

What can scientists use to determine the type of plant an organism consumed?
Agata [3.3K]
Answer: Carbon 12 and Carbon 13

In plant, the ratio of carbon 12 and carbon 13 isotopes is different depending upon the plant photosynthesis. The distribution of these isotopes in plant tissue can indicate the path way of carbon metabolism that is either C3 fixation or C4 fixation. This help scientist to know if the plant consumed by organism is C3 plant or C4 plant by measuring the isotopic signature of their collagen and other tissues.

This can help scientist know which plant is consumed by animals.
