What Is The Timer For The Increase In Genetic Variation That Occurs When Animals Move Into Another Population?

Answers

Answer 1
Gene flow is the answer
Answer 2

Gene flow is the timer for the increase in genetic variation that occurs when animals move into another population.

What do you mean by gene flow?

Gene flow is the transfer of genetic material from one population to another. If the rate of gene flow is high enough, then two populations will have equivalent allele frequencies.

Gene flow is the movement of genes into or out of a population. Such movement may be due to migration of individual organisms that reproduce in their new populations, or to the movement of gametes (e.g., as a consequence of pollen transfer among plants).

Gene flow is the transfer of genetic material from one population to another. Gene flow can take place between two populations of the same species through migration, and is mediated by reproduction and vertical gene transfer from parent to offspring.

Write a paragraph about air, land and water pollution.​

Answers

Answer:

AIR POLLUTION:

This tern is not something new, it has been existing since he time of industrial revolution where in big chimneys are pointed out in the air which releases harmful gases into the atmosphere. This phenomenon has been increasing since then as the industries have been developing simultaneously. Today, air pollutants have shown a great effect on plantations, health and life, decreasing the enjoyment of living, rising medical costs, causes global warming and also causes the destruction of the ozone layer.

One of the major causes of air pollution is the release of carbon di oxide into the atmosphere. This happens because of deforestation and fossil fuel burning. Sulfur dioxide is another main air polluter and is released into the atmosphere by the burning of sulfur containing compounds of fossil fuels. Sulfur dioxide is very harmful for the humans on high concentration and sulfur in the atmosphere is the main cause of acid rains. Chlorofluorocarbons also contribute to air pollution by reducing the ozone layer in the stratosphere. CFC’s are produced by the burning of plastic foam items, leaking refrigerator equipment and spray cans.

WATER POLLUTION:

Contamination of available natural water by industrial wastes and other waste products can be defined as water pollution. Factors causing water pollution can be categorized into two different groups; Point sources and Non- point sources.

Point sources are easy to identify and control. Some point sources of water pollution include waste products from factories, waste from sewage, waste from power plants , waste from underground coal mines and waste from oil wells. They are called point sources because these are the direct sources of water pollution and be reduced and monitoredNon- point sources are ambiguously defined and are much harder to control. The term non -point source encompasses a large range of sources like when rain and snow moves through the ground and picks up major pollutants and mover towards a major body of water, the runoff of fertilizers from farms animals and crop lands, air pollutants getting washed or deposited to earth, and storm water drained from streets parking lots and lawns.

LAND POLLUTION:

The contamination of and with different kinds of wastes is called land pollution. The major causes of land pollution are construction, domestic waste , industrial waste and agriculture.

The rising construction of building takes away the trees that takes away the homes of the animals living there. As there are more and more people inhabiting on our planet, the demand for food increases and the forests are cut down to make farm lands. In addition, Herbicides, pesticides, artificial fertilizers and animal manure are washed into the soil and pollute it. Tons of domestic waste is dumped everyday from homes offices etc. They can be recycled or burnt in incinerators. There are still more waste machinery products such as refrigerators and washing machines that are dumped in landfills simply because they cannot be recycled. Plastic factories, oil refineries, nuclear waste disposals, and large animal farms, all lead to land pollution.

WAYS TO STOP POLLUTION:

We can help to reduce global air pollution and climate change by few ways:

Driving a car that gets at least 35 mpg, walking, biking, and using public transportation, using CFL bulbs over incandescent bulbs, buying only energy efficient appliances, recycling newspaper, aluminum, and others, planting trees, avoid purchasing products that contains CFC’s, supporting much stricter clean air laws and enforcement of international treaties to reduce ozone depletion and slow global warming

A radioactive material has a half-life of 30 days. You begin with 4 grams of radioactive material.


a. How much of the original is left unchanged after 90 days?


b. After 120 days?


Give explanation. Don't go.ogle.

Answers

Answer:

a. 0.5 grams b. 0.25

Explanation:

Just use the half-life formula(I linked it below)

a. 4(1/2)^90/30=1/2

b. 4(1/2)^120/30=1/4

A. 0.5 grams is left unchanged after 90 days.

B. 0.25 grams is left unchanged after 120 days.

What is Half life?

The half-life of a radioactive isotope is defined as the time it takes for half of the radioactive isotope to decay. It is stable in specific radioactive isotopes. It is unaffected by circumstances. It is also independent of the initial amount of that isotope.

It can be find out by this formula:-

[tex]N=N_o (1/2)^n\\\\[/tex]

where, N=  quantity of the substance remaining

[tex]N_o[/tex]= initial quantity of the substance

n= number of half lives

For above given example,

Given that radioactive element X has a half-life 30 days

Hence the number (n) of half-lives in 90 days

n=90/30

n=3

The amount N of radioactive element X left after n=3 half-lives with initial amount [tex]N_o[/tex]=4 gm

[tex]N=N_o (1/2)^n\\\\\\N= 4 (1/2)^3\\N= 4(1/8)\\N= 0.5 gms\\\\\\[/tex]

For 120 days, n=120/30

so, n= 4

Then,

[tex]N=4(1/2)^4\\N=4(1/16)\\N=0.25 gms[/tex]

Thus, A. 0.5 grams is left unchanged after 90 days.

B. 0.25 grams is left unchanged after 120 days.

Describe three ways that the growth of suburban populations would have affected land and aquatic ecosystems around cities.

Answers

Answer: The three ways the growth of suburban populations( urbanisation) would affect the environment include:

--> Insufficient water availability,

--> Waste-disposal problems, and

--> High energy consumption.

Explanation:

The growth of suburban population is also called URBANISATION. This is defined as the rapid growth of an urban area which occurred due to the movement of individuals from rural areas into the urban area. There are different reasons why individuals migrate to urban areas these include:

--> for a better access to health care services

--> for more education opportunities

--> To combat the problems of unemployment and

--> for better participation in political and social activities.

The three ways the growth of suburban populations( urbanisation) would affect the environment include:

--> Insufficient water availability: the increase in the urban population creates a high demand for water use both for industrial and domestic uses.

--> Waste-disposal problems, and

--> High energy consumption.

Deforestation, Water pollution, Introduction of invasive species

Explanation:

For ages, human beings have been altering the natural ecosystems and causing irreparable damages to nature. Development drove to an unmeasurable advance over new unpopulated areas.

Some of the principal human activities responsible for biodiversity loss are

• the uncontrolled use of unrenewable resources,

• overexploitation of renewable resources;

• land destruction for the mining industry, farming and cattle industry, buildings, and other infrastructures;

• the unplanned advance of cities, and opening of new roads to connect those cities.  

All of them involving

deforestation and fragmentation of natural landscapes; water, air, and soil pollution, species loss, and reduction of biodiversity. Introduction of invasive species.

And the growth of suburban populations is a frequent human activity causing an impact on nature. To mention a few ways in with this action might affect ecosystems, we can name the followings,

Deforestation:        

The growth of suburban populations is indefectibly related to deforestation.  New open areas are needed for buildings, roads, and service establishments, such as natural gas or water ducts, light, and others. There hardly exists planning about the cities´ growth and conscientious conservation of nature.

Water pollution:  

Water is severely polluted while constructing buildings and roads. The wastes of materials used for construction, oil coming from transport and machinery, human wastes, among other sources of contamination reach the rivers or lakes, polluting them and altering the natural equilibrium.

Introduction of invasive species:

It is very common to use ornamental vegetable species, proceeding from other areas or countries to arrange the gardens, streets, and parks. These species might become invasive and uncontrollable, causing severe damage in native endemic species by competing for resources. The whole ecosystem structure changes.

Deforestation, water pollution, and the introduction of invasive species are some of the causes of biodiveristy loss.
