Answer: d. all of the above

Fossil fuels such as coal, oil and gas are beneficial sources of energy used by the human society. Fossil fuels are non- renewable resources, which are produced after millions of years of geological and biological activity taking place inside the earth crust. Human society is mainly dependent upon the fossil fuels to maintain it's energy needs.

There are some negative consequences associated with fossil fuels:  

Environmental consequences: Fossil fuels are used for generation of energy in the power plants and by the automobiles. These sources releases partially and completely combusted products which includes the poisonous gases causing air and water pollution.

Economic consequences: Fossil fuel use is related with economic crisis because fossil fuels are non- renewable resources, which cannot be replenished once used. They are expensive and many commercial energy generation processes are dependent on them such as electricity, transportation and others.  

Development hindrances: Large dependence on fossil fuels creating an hindrance on development process. As, there are very few findings which are resulted which could replace the fossil fuels, these finding can be beneficial for the environmental and economic point of view.

Svetach [21]

Answer:

Explanation:

Archae and bacteria are similar to each other in that

1. They are both prokaryotes meaning they do not have membrane bound nuclei and organelles.

2. Presence of flagella in both that helps them to move in their environment by propelling them. The flawless are threadlike structures used for movement

Archae and eukaryotes are similar in that

1. At the molecular level, they use the same molecular machines eukaryotes use in DNA synthesis and other processes

2. Some eukaryotes and the archae use asexual reproduction

Both some studies noted that archea are closely related to the bacteria than to eukarya

You are making an illustration of the life cycle of an average star and the life cycle of a massive star as part of a computer a
Leya [2.2K]

The average star cycle: nebula, protostar, main sequence, red giant, white dwarf. The massive star cycle:  nebula, protostar, main sequence, super red giant, supernova, black hole, neutron star.

The star cycle is the sequence of changes that a star undergoes throughout its existence.

<h3>The evolutive stages of an<u> average star</u> are </h3>

  • Nebula: Stars are born from the nebula that is the dust and gas particles condensation due to gravity effect in the interstellar clouds

  • Protostar:  It is a more advanced level of condensation.

  • Main sequence. Equilibrium between gravity and nuclear fusion helps the star keep stable as long as the fuel lasts. The two main types are

• <em>Orange dwarf</em><em>: </em>between the red dwarf and the yellow dwarf

• <em>Yellow dwarf:</em> Like the sun

  • Subgiant: occurs when orange and yellow dwarfs finish their main sequence and start to run out of fuel, expanding.

  • Red giant. After the subgiant stage, the star enters a giant phase. The star can reach a size of up to 100 times its current size.

  • White dwarf. When average-sized stars run out of fuel, the red giant begins to disintegrate, losing its outer layers and exposing its core, which will become a white dwarf.

<h3>The evolutive stages of a<u> </u><u>giant star</u><u> </u>are </h3>

  • Nebula

  • Protostar

  • Main sequence. There are two main types

• <em>Yellow supergiant</em>. Extremely short phase. Almost no stars are known to be in this stage. The star swells on its way to becoming a red supergiant.

• <em>Red supergiants</em> are the largest stars in volume, but not in mass.

  • Supernova. When fuel is over in the red supergiants, the gravitational collapse produces a violent explosion originating the supernova.

  • Neutron star. A celestial body that remains as a remnant after the explosion gives rise to a supernova.
