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
Answer:
Pollination
Explanation: If you have ever seen bee movie, you know that pollen is the most essential ingredient to flowers, which is transported and spread by bee's. if there were no more bees, there would be no way to pollinate the flowers, causing them to wither and die. Fortunately, there are other pollinators, but bees are one of the most important.
Because the soil didn't have the same nutrients it has now due to lack of decomposition of other plants and animals.
Answer: True
Explanation:Carbon dioxide is transported is transfer in 3 basic ways to human cells.
About 20 % of C0 2 is transported as Carbaminohemoglobin to reach the lungs carbon dioxide binds directly to the amino acid moieties on the globin portions of the haemoglobin to form carbaminohemoglobin. This is a reversible reaction as shown below.
CO2 + Hb ↔ HbCO2.
The reversible binding of C02 to the haemoglobin is due to the the partial pressure of carbondioxde. In the lungs the partial pressure of C02 is low. Therefore C02 is unbounded from the HB and leaves in the lungs, thus the blood leaving the lungs for the body tissues has low partial pressure C02. Compare to the blood in the tissues with high partial pressure of C02 from metabolic activities of cellular respiration. The C02 therefore diffuses from the tissues to bind with HB to form Carbaminoheamologbin.
In addition C02 is transported by other means.
1. As bicarbonate 70% of the Co2 in the blood is transported and bicarbonate buffer.
CO2 + H2O CA ↔ H2CO3↔H+ + HCO3
2, As soluble carbon dioxide which dissolves directly in to the blood stream; this is about 7-10%
