Summarize why the pyramid of energy can never be inverted like the pyramids of numbers and biomass can.
Art [367]
Base on one of the Law of Thermodynamics, the amount of available energy decreases whenever energy is changed in form (which includes a transfer from one trophic level to another). So, as we go from the first trophic level to the top trophic level, the amount of available energy becomes less and less.

What is most likely consequence if a group of living organisms is unable to adapt to changing conditions within the Earth system
Charra [1.4K]

Answer:

If a group of living organisms is unable to adapt to changing conditions with the earth's system, it shall face extinction.

As time goes by, the earth's systems keep changing, either negatively or positively.

If the earth's temperature decreases then living organisms shall adapt to surviving in cold conditions, they shall for instance grow heavy fur cover on their skin to cover them from the cold.

Those that fail to adapt to the cold conditions shall face extinction by being overpowered by cold related complications.

If you look at the karyotypes of person a and person b and discover that they look alike, what can you infer is the same about t
nataly862011 [7]

Answer:

They belong to the same species

Explanation:

A karyotype is an image of the chromosomes of a cell usually taken by an atomic microscope in a cell arrested in the prophase stage of mitosis –because the chromatin is well condensed.

It is difficult to discern the difference between individuals of the same species using karyotype unless in exceptions of chromosomal disorders like Klinefelter's syndrome and Turners syndrome, and etcetera.

However different species will most likely differ in the number of chromosomes, the chromosomal sizes and their arms lengths.
