What is the term for the breakdown of glucose in the absence of oxygen?

Biology
1 answer:
Alekssandra [29.7K]3 years ago
6 0

Answer:

Fermentation

Explanation:

In the absence of oxygen, the cell uses a process called fermentation. Fermentation doesn't break the sugar down any further, it simply helps reset the system so that more sugar can be broken down.

Because aerobic respiration breaks the sugar all the way down, it releases much more energy than fermentation.

Hope this helps :)

What refrigerant safety group classification has the highest flammability and the highest toxicity?
timama [110]

Answer;

-B3

Explanation;

Refrigerants are divided into two groups according to toxicity:

-Class A signifies refrigerants for which toxicity has not been identified at concentrations less than or  equal to 400 ppm;  and

-Class B signifies refrigerants for which there is evidence of toxicity at concentrations below 400 ppm.

They are also divided into three groups according to flammability:

-Class 1 indicates refrigerants that do not show flame propagation when tested in air at 21°C and 101  kPa;

-Class 2 indicates refrigerants having a lower flammability limit of more than 0.10 kg/m3  at 21°C and  101 kPa and a heat of combustion of less than 19 kJ/kg;

-Class 3 indicates refrigerants that are highly flammable as defined by a lower flammability limit of less  than or equal to 0.10 kg/m3  at 21°C and 101 kPa or a heat of combustion greater than or equal to 19  kJ/kg.

-Therefore; the answer for the above question would be Class B and class 3.

Aleksandr [31]

In the 1800s, Darwin explains the origin of species. As species originate through adaptation by natural selection.

Answer: Species originate through adaptation by natural selection

<u>Explanation: </u>

The Origin of species through natural selection is a pioneering scientific effort of the British naturalist Charles Darwin in England. Darwin's theory is that organisms are gradually evolving through what is called "natural selection"

It is a process in which organisms change due to hereditary changes in physical or behavioural traits. Changes that allow the body to better adapt to its surroundings, help it survive and have more offspring.
