Biology

In northern canada, a population of rabbits was predominantly white in color. the allele for white color is recessive (g), while the allele for gray color is dominant (g). over the last several decades, the average annual temperature of this area has increased, and the long-term deposits of ice and snow have become scarce. we see the result of this change in the graph above. how would hardy-weinberg explain this change in terms of allelic frequency? a) no population can maintain equilibrium indefinitely. b) random mating occurred among the rabbits

Its C: Genetic variation existed. Natural selection occurred. Allelic frequencies changed.

Biology

Evolution is a change in frequencies of alleles in the gene pool of a population. This definition of evolution was developed as a result of the work in the 20th century by Hardy and Weinberg. Through mathematical modeling based on probability, they concluded that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of evolutionary influences. Evolution will not occur in a population if seven conditions are met: 1. mutation is not occurring 2. natural selection is not occurring 3. the

D.

Explanation:

Explained by natural selection. Those with favored traits in an environment are more likely to survive and pass down the allele. Thus in this situation a grey rabbit is more likely to survive and blend in.

Mathematics

The table shows the population density for the state of texas in various years. find the average annual rate of change in the population density from 1960 to 2000. do not round your answer. the population density increased by about people per square mile.

Step-by-step answer

P Answered by PhD

1.08 people per square mile per year.

Step-by-step explanation:

The table shows the population density for the state of Texas in various years.

We have to find the average annual rate of change in the population density from 1960 to 2000.

There was 36.4 people per square miles of population density in the year 1960.

And there was 79.6 people per square miles of population density in the year 2000.

Therefore, the annual average rate of change of population density will be given by

= $\frac{\textrm {Total change in population density}}{\textrm {Total change in years}}$

= $\frac{79.6 - 36.4}{2000 - 1960}$

= 1.08 people per square mile per year. (Answer)

Step-by-step answer

The population density increased by about 1.08 people per square mile.

Step-by-step explanation:

$\mathbf{Average \ annual \ rate \ of \ change \ in \ population \ density =\frac{Change \ in \ population \ in \ density}{Total \ number \ of \ years}}$

Population in year 1960 is 36.4 people per square mile.

Population in year 2000 is 79.6 people per square mile.

Change in population density between year 1960 and 2000 is:

79.6 - 36.4 = 43.2

Total number of year between year 1960 and 2000 is:

2000 - 1960 = 40

Substituting the values in above formula:

$\textrm{Average annual rate of change in population density}=\frac{79.6-36.4}{2000-1960}$

$\textrm{Average annual rate of change in population density}=\frac{43.2}{40}$

$\therefore\mathbf{Average \ annual \ rate \ of \ change \ in \ population \ density=1.08}$

Biology

Which of the following environmental changes could most likely kill a large portion of a population? a. a flash flood b. cyclic temperature fluctuations c. an annual dry season d. above-average precipitation levels over a year

Step-by-step answer

P Answered by Specialist

8

A. A flash flood

Explanation:

A flash flood would most likely kill a large portion of a population because it the only event that happens instantaneously and can cause a large amount of damage. The other environmental changes happen over time and/or are based on already occurring cycles.
