Dos mecanismos por los que pueden formarse dos especies a partir de una.

Biology
1 answer:
Sunny_sXe [5.5K]3 years ago

Answer: English: New species arise by a process called speciation, in which an ancestral species is divided into two or more descendant species that are genetically different from each other and can no longer reproduce with each other. Darwin conceived speciation as a branching process.

<h3> Español: Las especies nuevas surgen por un proceso llamado especiación, en el que una especie ancestral se divide en dos o más especies descendientes que son genéticamente diferentes entre sí y que ya no pueden reproducirse entre ellas. Darwin concebía la especiación como un proceso de ramificación. </h3>

Explanation:

En Biología, los mecanismos de aislamiento reproductivo o barreras a la hibridación son el conjunto de características, comportamientos y procesos fisiológicos que impiden que los miembros de dos especies diferentes puedan cruzarse o aparearse entre sí, producir descendencia o que la misma sea viable o fértil.

answer 1:

Environmental Pollution occurs in different forms; air, water, soil, radioactive, noise, heat/ thermal, and light

Air Pollution

Water Pollution

Soil pollution

Noise pollution

Radioactive pollution

Light pollution

Humans are the main cause of water pollution, which is triggered in many ways: by the dumping of industrial waste; due to temperature rise, that cause the alteration of water by reducing the oxygen in its composition; Or due to deforestation, which causes sediments and bacteria to appear under the soil

Most of this air pollution we cause results from the burning of fossil fuels, such as coal, oil, natural gas, and gasoline to produce electricity and power our vehicles. Carbon dioxide (CO2) is a good indicator of how much fossil fuel is burned and how much of other pollutants are emitted as a result.

Effects:

Nutrient pollution can cause toxic algal blooms in drinking water sources that create toxins that kill fish and other aquatic animals. Direct exposure to this toxic alga causes serious health problems in humans including neurological effects, respiratory problems, stomach and liver illness, and rashes.

answer 2:

The Industrial Revolution brought rapid urbanization or the movement of people to cities. Changes in farming, soaring population growth, and an ever-increasing demand for workers led masses of people to migrate from farms to cities. Almost overnight, small towns around coal or iron mines mushroomed into cities.

anwer 3:

advantages are

1_A Fuel Supply That Never Runs Out

2_Zero Carbon Emissions

3_Cleaner Air and Water

4_A Cheaper Form of Electricity

5_Renewable Energy Creates New Jobs

disadvantages are

1_Higher Capital Costs

2_Electricity Production Can Be Unreliable

3_Energy Storage Is a Challenge

4_It’s Impacted by Environmental Conditions

5_Renewables Still Have a Carbon Footprint

anwer 4:

Hazardous waste can be treated by chemical, thermal, biological, and physical methods. Chemical methods include ion exchange, precipitation, oxidation and reduction, and neutralization. Among thermal methods is high-temperature incineration, which not only can detoxify certain organic wastes but also can destroy them.

answer 5:

You could do this by:

1_Try to stay away from disposable goods. In particular, paper plates, cups, bottles, and plastic utensils.

2_Buy durable and reusable goods. ...

3_Pack your lunch in a reusable box rather than foil or cling film.

4_Buying products with less packaging. ...

Explanation:

Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). Mitochondria are structures within cells that convert the energy from food into a form that cells can use.

Hope this helps!
