Why are all organisms on Earth expected to have differing optimum functional temperatures?
answr because
1.the different oraganism have different tolerance to temperature stress.
2.many organisms are not thermocinformers .many animals and plants use certain activities to get control over body temperatures .
3.an orgaisms thermal sensitivity isnt constant but often shifts to acute heat shocks or to seasonal hibernation.
4.many organisms are not active during whole season mostly in arctic reason.
Why are all organisms on Earth expected to have differing optimum functional temperatures?
Why do organisms have differing optimal temperatures?
1). what is scientific explanation for why all organisms on earth have DNA, RNA, and use ATP? 2). what are homologous structures? give a real world example of homologous structures.
Why most enzymes have an optimum pH of around 7 while pepsin will be optimum at ph 2? Give a detail explanation!
In this course we surveyed some of the major kinds of organisms on Earth, all of which contribute to our planet's biodiversity. List and explain THREE ways that biodiversity contributes to the general functioning of ecosystems. Your answer should include consideration of some of major kinds of organisms covers in class, and the key roles those organisms play (energy capture and transformation, symbiosis, predation, parasitism, photosynthesis). Conclude with a brief assessment of the possible negative impact(s) of species extinction (i.e....

In general, why do organisms that have high survivorship have low fecundity? In general, organisms have a finite (i.e., limited) amount of energy that can be used for either promoting survival or promoting reproduction. o Organisms that produce lots of offspring don't need to survive for long periods of time. O Organisms that are capable of surviving long periods of time don't need to produce lots of offspring. This is an adaptation that organisms with high survivorship have acquired.
if the original atmosphere of earth lacked oxygen, The first organisms can have Carried on anaerobic respiration Been eukaryotic Carried on aerobic respiration Produced ozone
Lab Exercise 4B ins with a higher 9. Why do organisms found at low temperature have membrane proteins with a percentage of alpha helices compare to beta sheets? 10. Are amino acids outside the active site important for optimal function of the Explain your response. 11. Homologous sequences: A. are expected to have very similar sequences in related organisms B. are expected to have similar sequences in related proteins but from unrelated distantly related organisms C. may have become similar...
a) Will all gram positive organisms grow on a rose agar plate? ecplain why or why not. b) Will all gram negative organisms grow on a MAC agar plate? explain why or why not. c) Can colony morphology be done from a MAC or Rose agar plate? why or why not.
6. The lipid membranes of organisms that live in extremely cold environments have glycerophospholipids that contain an increased percentage of unsaturated fatty acid tails (as compared to organisms that live in more moderate temperatures). Why would this be the case? Provide an explanation based on the fluidity of the lipid membrane. 7. Given its composition and structure, do you think K" ion or indolewould ) would be able to better move through the lipid membrane? Provide an explanation based on...
