Analyze the movement of carbon through the abiotic and biotic parts of the carbon cycle
luda_lava [24]

The movement of carbon through the abiotic and biotic parts of the carbon cycle is the following:

In the carbon cycle, carbon is moved between the four reservoirs where it is in different states:

  • Atmosphere, carbon is in the form of carbon dioxide (CO2) by joining with oxygen in the form of gas.
  • Terrestrial biosphere, carbon is found in the elements that make up terrestrial and coastal ecosystems, in non-living organic matter, and in the soil.
  • Oceans, carbon is part of the hydrosphere, it is found in dissolved organic carbon, in marine organisms and in non-living matter.

The water vapor produced and released into the atmosphere also promotes gas exchange between the atmosphere and the ocean, allowing carbon to dissolve in the water, where it is fixed by photosynthetic plankton.

  • Sediments: carbon is part of the geosphere, the excess carbon in decomposing organic matter, which is not captured and processed by decomposing life forms, it will pile up and sediment at the bottom of the oceans or in the various layers of the earth's crust, where it forms fossils, hydrocarbon deposits or reactive sediments.

During photosynthesis, green plants take CO2 from the abiotic environment and incorporate the carbon into the carbohydrates they synthesize.

Part of these carbohydrates are metabolized by the same producers in their respiration, returning carbon to the surrounding environment in the form of CO2.

That is, the return of CO2 to the atmosphere occurs when living beings oxidize food while breathing, producing CO2.

The final products of combustion are CO2 and water vapor.

Therefore, we can conclude that the movement of carbon between the abiotic environment and biotic factors (living organisms) defines the carbon cycle.

Why has electricity increased so much over the past 20 years
m_a_m_a [10]

Answer:

It’s been more than two decades since Britain’s retail electricity market was opened to full competition in 1999. Before that, retail supply was provided by state-owned entities with regional monopolies. Today, all consumers, including households and businesses, are able to “shop around” for their electricity, switching to a different supplier or tariff to take advantage of better prices and services.

In principle, that is exactly what liberalised retail markets are supposed to provide: greater consumer choice and protections. But that’s only the case if it’s easy for consumers to switch suppliers and for new suppliers to enter the market. That’s how markets are supposed to stay competitive to deliver low prices and a high quality of service. That was the great hope of electricity policy in 1999, but after two decades, there’s little to celebrate.

To enhance competition, smaller suppliers have been exempt from contributing towards the cost of decarbonisation policies. Known as “the threshold obligation”, this encouraged the entry of smaller companies into Britain’s retail electricity market, but the increase from six suppliers in 1999 to more than 70 in 2019 came at a cost. Many new suppliers have gone bankrupt due to unsustainable business models, resulting in consumers footing unpaid industry bills

Which characteristics do all Protista have in common?
zysi [14]
Protists are eukaryotic organisms that cannot be classified as a plant, animal or fungus. They are mostly unicellular, but others like algae are multicellular. Protists have mitochondria responsible for respiration to produce energy to be used by cells. Additionally, they can be parasites and mostly prefer aquatic or moist environments. They may be classified as animal-like protists (heterotrophs and have ability to move), Plant-like (autotrophs that photosynthesize) and fungi-like (heterotrophs with cells that have cell wall and reproduce by spore forming). Protists reproduce by asexual means (e.g. budding) or sexually. Therefore, in this case we may conclude that they are all parasites and reproduce sexually or asexually.

Calculate the number of cells in a hummingbird, assuming it has a mass of 10-2 kg.
Nikitich [7]

The number of cells in a hummingbird, given the data is 10¹² cells

<h3>How to determine the mass of one cell</h3>

We'll begin by obtained the mass of a cell. This can be obtained as illustrated below:

Mass of 1 cell = 10 × mass of bacterium

But

Mass of bacterium = 10⁻¹⁵ Kg

Thus,

Mass of 1 cell = 10 × 10⁻¹⁵ Kg

Mass of 1 cell = 10⁻¹⁴ Kg

<h3>How to determine the number of cells in the hummingbird</h3>

The number of cells in the hummingbird can be obtain as follow:

  • Mass of 1 cell = 10⁻¹⁴ Kg
  • Mass of hummingbird = 10⁻² Kg
  • Number of cells =?

Number of cells = Mass of hummingbird / mass of 1 cell

Number of cells = 10⁻² / 10⁻¹⁴

Number of cells = 10¹² cells

Thus, the number of cells in the hummingbird is 10¹² cells

Complete question

Calculate the number of cells in a hummingbird assuming the mass of an average cell is ten times the mass of a bacterium. The mass of a hummingbird is of the order of 10⁻² Kg and that of a bacterium is 10⁻¹⁵ Kg
