Which of the following investigations would shed the most light on the future distribution of organisms in temperate regions that are faced with climate change?

remove, to the mineral soil, all of the organisms from an experimental plot, and monitor the colonization of the area over time in terms of both species diversity and abundance. quantify the impact of man's activities on present-day populations of threatened and endangered species to assess the rate of extirpation and extinction. compare and contrast the flora and fauna of warm/cold/dry/wet climates to shed light on how they evolved to be suited to their present-day environment. look at the climatic changes that occurred since the last ice age and how species redistributed as glaciers melted, then make predictions on future distribution in species based on past trends.

Explanation:

Organisms in temperate regions are adapted to the normal temperate climate.

As different factors cause climate change in the temperate climate, living organisms shall be faced by the problem of adapting to the new changes, moving to friendlier areas or facing extinction.

The above experiment would be appropriate since the living organisms in the ice age were faced with the same problem of climate change and adapting to the new climate, this shaped their current distribution.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
