faust18 [17]

Answer:

The electron microscope

Explanation:

<u>The microscope that would be best suited to study the inner structure of the chloroplast would be the electron microscope.</u>

<em>The electron microscope has a high magnifying property due to the fact that it uses a beam of accelerated electrons as a source of illumination, unlike the light microscope that uses visible light. While the light microscope might be enough to see the inner portion and the organelles of the cell, the tiny nature of the inner structure of the chloroplast means that the light microscope will not be able to view the details. A more powerful microscope like the electron microscope would be required.</em>

If scientists are wrong about Earth's age based on radioactive material and the decay rates are really much faster, how would nu
kupik [55]

Nuclear power plants use the energy originating from the splitting or uranium atoms to produce steam, which in turn drives a turbine generator.

The main problem with this form of energy production is the byproduct from the nuclear reactors known as radioactive waste. Although it is no longer efficient for the energy production, this waste is still radiating large amounts of heat and radiation. Thus, they are very hazardous as they are fatal on direct exposure and can contaminate the environment.

Due to the extremely long half-life, long term storage for this waste is extremely problematic.  However, if the decay rates were much faster, then the half-life would also be much shorter. Thus, short term storage solutions could be found.

Excepting the nuclear waste and the potential accidents (which are minimized in modern plants), nuclear energy does not immediately affect the climate on earth. With short half-lives, nuclear energy would perhaps become more popular than solar or wind energy as it is more reliable and efficient.

Dmitry_Shevchenko [17]

Answer:

α = 0 if β= 0

Explanation:

If both species want to persist in the same environment and their niches are also over lapping then both of the co-efficient values should be equal. There are two possibilities on these values for persistence. One is that one should compromise to the change produced by the invasive specie and two is that the new specie should compromise if he wants to stay (<em><u>Assuming that there is no competition</u></em>). In this way their niches won't overlap to a greater extent and therefore better chances of survival for both.
