Which of the following observations would support part of the energy-diversity hypothesis?
1. The total number of plants per site (not plants per species) is higher in sites with high actual evapotranspiration (AET).
2. The total number of plants per site (not plants per species) is lower in sites with high actual evapotranspiration (AET).

Expert Solution

Temperature is not energy; it is a measure of the tendency of a body to gain or lose heat. Two bodies are said to be at the same temperature if there is no net heat flow between them; this is the definition of temperature. Because evapotranspiration (AET) is a function of temprature, Evapotranspiration in plants occurs due to temprature and it is a main driving force for photosynthesis. Hence, the ist possibiltiy is, any hypothesis that temperature controls diversity directly has the simple consequential prediction that diversity will be greater where temperatures are higher.

A second possibility is that diversity is controlled not by mean temperature, but by variability in temperature. Thus lots of work has been published on energy -diveristy hypothesis but not any single has absolute authentication. So on the basis of above discussion, we can conclude that the total number of plants per site is higher in site with high temprature means high actual evapotranspiration.

For which one of the following observations were both Lamarck's hypothesis and Darwin's hypothesis in complete agreement? More complex species are descended from less complex species. Gradual evolutionary change explains why organisms are well-suited to their environments. Acquired characteristics are inherited. Use and disuse of organs determines their size in progeny.

Which one of the following experimental results does not support the hypothesis that the ribosome is a ribozyme? Group of answer choices Peptidyl transferase activity is not inactivated by treating the ribosome with detergent. There are no proteins observed within 18 angstroms of the peptidyl transferase active site in the crystal structure. Peptidyl transferase activity can be inactivated by base changes in the rRNA. Ribosomes from thermophilic organisms are more stable than from E. coli. All of the answers support...

Darwin used observations of homology from comparative embryology to support his hypothesis of “descent with modification.” Which of the following observations about the role of Hox genes in the development of insects and mammals are consistent with Darwin’s hypothesis? Select all that apply. (Note that all of these statements are true, but not all of them offer support for his perspective. You’ll need to apply what you know both about Hox genes and the idea of descent with modification, to...
