Answer: The estimated population is 1250 mice
Explanation: The method use was marked and recapture, in which individuals are marked in the first capture and after some time biologist trap a new group of individuals that can be or not marked
Whit this data is possible to estimate the size of a population applying the Peterson method but is important to make some considerations such as:
1. All indivuals have the same probability to be capture
2, The population remain constant in terms of birth and death rate.
Taking this into account, the formula that allows to determine the size of the population is:
N=CM / R
where N is the size of the population, C is number of indivuals trapped in recapture, M is number of individuals marked in the first capture and R is the number of marked animals trapped in recapture
In this case:
N = 250 * 200 / 40 = 1250
Answer:
Imagine that you are a doctor in maternity ward. During your last shift, 20 babies were born. 10 had blue eyes, and 10 had brown eyes. Remember genotypes are the two alleles given for each trait written with a letter . For this activity 8 - brown eyes b=blue eyes. Phenotypes are the physical appearance of the trait. Given the phenotypes, what are the possible genotypes for these babies? The possible genotypes of these babies are Bb, Bb, bb, bb
Explanation:
Bb= Brown eyes babies
bb= blue eyes babies
from the above analogy, it is crystal clear that the babies are of equal genotypic number which reflects 10:10
Answer:
1. Location: Histosols are the soils which are found in the grasslands, swamps and marshes, whereas the aridosols are soils that are found in desert regions.
2. Color: Histosols are soils which are rich in organic matter therefore, are dark colored, whereas the aridosols are soils that lack organic matter, hence are light in color.
3. Water retention capacity: Histosols exhibit higher water retention capacity as compared to the aridosols.
4. Rate of decomposition: Rate of decomposition is higher in the histosols as compared to aridosols.
That's because they are in the same climate zone. The earth's climate zones change going from the north pole to the equator, and then from the equator to Antarctica, like a mirror image. The two are found in the same zones on the opposite hemispheres.
