"An oxygen-rich environment would cause a mass extinction of prokaryotes."

Biology
1 answer:
Flauer [41]3 years ago
6 0

<u>Answer: </u>

"An oxygen-rich environment would cause a mass extinction of prokaryotes."  Supports current scientific theories of how life might have originated on Earth.

<u>Explanation: </u>

The reacting power of oxygen increases rigorously in an oxygen- rich environment, which leads to huge fire ignition even with the slightest spark which is generally non hazardous at all. Many prokaryotic organisms do not need oxygen as they perform anaerobic respiration. Oxygen is dangerous for some prokaryotes.  

There were some prokaryotic organisms who were giving out oxygen as waste. Such excess amount of oxygen was hazardous for the environment and hence mass extinction was required to keep a check on the excess amount of oxygen being released.

Select all of the true statements regarding non‑shivering thermogenesis.
lora16 [44]

Answer:

a, b, d y e

Explanation:

We can define thermogenesis as the method of production of lime or temperature that a living body generates, in biology it is studied that this does not occur in all animals, but is seen in so-called warm blood and some plants, there are three types of processes identified in animals:

NEAT: defined as thermogenesis that occurs without the presence of physical activity

DIT: defined as the thermogenesis that occurs with physical activity

EAT: defined as the thermogenesis that occurs with the consumption of food or diet

Thermogenesis under the thermogenin protein found in brown adipose tissue produces a disengagement of protons within the mitochondria, prevents ATP synthesis and is capable of inducing temperature with the flow of protons, it also intervenes by increasing glycolysis, lipogenesis and gluconeogenesis with which its final result in these processes is the production of energy. The effect of the sympathetic nervous system and thyroid hormones that can balance heat production without generating abnormal movements such as tremor is also recognized.

Thus we deduce that:

electron transport allows heat flow without causing tremors

Thermogenin is involved in allowing protons to enter the mitochondria and the ATP production process is carried out.

hydrolysis of fatty acids occurs in the presence of norepinephrine

in brown adipocytes ATP synthase can be avoided
