Scientists believe that the re-creation of the origin of life in the laboratory would provide important clues to how life began
ollegr [7]

From a science standpoint, there is always the potential to expand knowledge about many subjects through detailed experimentation. One of the first challenges will be managing the considerable number of variables and conditions relative to the environment, chemical conditions, atmosphere, temperature, water conditions and sources of energy that existed on early Earth, but which are not well known.

Regardless of whether the initial conditions could even be perfectly replicated, there are no natural processes that can chemically assemble the required elements into increasingly more complex biochemical assemblies that could eventually lead to even the simplest initial organism.

As far as the the experimental design steps that "would best explain the origin of life," there are none within the context of a single experimental setup that could accomplish the task. More importantly, because no natural conditions suffice, it would take extreme levels of intelligent design in the configuring and processing at all phases and steps of the experiments, making no natural condition simulating primordial Earth realistic or possible.

The destruction of molecules (assumed to mean disassembly into elements and smaller molecules) is not systematically precise enough to produce the right concentrations of the right gases.

Using viruses grown from plants is not viable as it requires the use of living organisms to accomplish an outcome of dubious relevance.

Creating organisms is intelligent design, not natural working processes and is a totally independent activity whose comparability to the true initial conditions is undetermined.

Breaking down fossils is not viable because fossils do not contain all required materials and compounds required to emulate initial conditions.

The net is that the range of experimentation will demonstrate intelligent design, not emulate initial conditions, and require an extremely wide range of efforts with no guaranteed result.

If a Killer whale is feeding at the fifth trophic level, how much phytoplankton mass is required to add each gram of new mass to
nydimaria [60]

<span>Since a phytoplankton is on the 1st trophic level. Therefore the energy transfer from the phytoplankton to the Killer whale must be on the 4th power.</span>

To calculate:

Mass of phytoplankton required = 1 gram / (0.1)^4

Mass of phytoplankton required = 10, 000 grams

Therefore, 10, 000 grams of phytoplankton is needed to add 1 gram of mass to the Killer whale.

Chromosome structure can be microscopically observed best during.
kirza4 [7]

Answer: chromatin condenses into chromosomes and can be best observed in prophase.

Explanation: chromosomes can’t be visualised by a light microscope except during cell division (mitosis or meiosis). The individual chromosomes become visible as the chromatin is wound tightly and are most clealry seen in late prophase.
