Describe the four stages of the hypothesis for the origin of life on earth by chemical evolution

Biology
1 answer:
VashaNatasha [74]3 years ago
4 0
It would be nice to see the 4 stages titled to have a clue to what they could be. You see, chemical evolution is a myth, like Darwin's "warm little ponds." There are no naturalistic processes that have any power to accomplish the complex, diverse, extensive and highly non-entropic assembly of biochemical elements, molecules and assemblies into even the simplest life.

There is no primordial soup, panspermia is a distraction, none of the intractable issues for the origin of life.

Logically, the first step is collection of all elements, second, first level assembly of amino acids lipid membranes, proteins, third, higher level combination of biochemical molecules and generation of nucleotide coded DNA containing the processing code for generation and production of RNA, enzymes ribozymes and all other cellular functions, then fourth, the execution of all metabolism, nutrient collection, waste elimination and reproduction consistent with a living organism. Admittedly speculative since chemical evolution is a myth.

Describe how The Carbon Cycle works.
shutvik [7]

Carbon cycle refers to an array of procedures by which the compounds of carbon are interconverted in the environment, comprising the inclusion of carbon dioxide into living tissue by the process of photosynthesis and then getting back into the atmosphere via respiration, the burning of fossil fuels, and the decomposition of dead organisms.  

The following are the steps that illustrate how the carbon cycle functions:  

1. Carbon enters the atmosphere as carbon dioxide from combustion and respiration.  

2. The absorption of carbon dioxide takes place by the producers to manufacture glucose in photosynthesis.  

3. The animals feed on the plant passing the carbon components through the food chain. The majority of the consumed carbon is exhaled in the form of CO2, which was produced at the time of aerobic respiration. The plants and animals die eventually.  

4. The dead plants and animals get dissociated by the dead organisms and return the carbon present in their bodies back to the atmosphere as CO2 by the process of respiration. In certain occasions, the dead plant and animals get converted into fossil fuel, which is available in future for combustion.

How do archaea and bacteria differ?​
Lunna [17]

Answer:

The archaea and the bacteria both are prokaryotes. However, the genetic makeup of the archaea is more similar to the eukaryotes. Moreover, they have differences, in their metabolic pathways, genes and the enzymes possessed by them.

Explanation:

The differences between Archaea and bacteria:

1. The cell wall of the bacteria consist of peptidoglycan, while the cell wall of the archaea consist of pseudo-peptidoglycan.

2. The bacteria are capable of spore formation, which can lie dormant for long periods of time until a suitable condition is found for their growth. The archaea are not known to form such spores.

3. The genes of the archaea are more similar to the eukaryotes than the bacteria.

4. The bacteria are found everywhere where the living conditions are suitable (soil, air, living beings, non-living things). the archaea are capable of surviving in extreme conditions (hot springs, salt brine).

5. The bacteria use the process of glycolysis and follows Kreb's cycle for glucose break-down. The archaea do not undergo glycolysis or Kreb's cycle.

Examples of the energy pyramid to explain production, distribution, and use of food resources
miss Akunina [59]
The energy pyramid (also called ecological pyramid) quantifies the energy transfer from one organism to another along the food chain.
