I believe the answer for the above question is that it cannot bind to the inducer. An inducer molecules regulates gene expression, it can bind to protein repressors or activators. The binding of the inducer to the repressor prevents the repressor from binding to the operator. A super repressor is a repressor that binds to an operator and is non-iducible so it can not be removed. These are dominant because they will bind and never be removed, even if the wild type is attached to one, once it is removed the lac IS may attach and never be removed.
A. A steep positive slope. Since the speed is going UP, it is positive. Since it is happening quickly, the line will jump steeper. Hope that helps!
I'd appreciate if you attached the article as well. But i'm 90% sure it's option D. A quick search reveals that it was dubbed Black Saturday due to rapid fire growth within Yellowstone park. Option D is really the only one that relates to that at all.
Hope this helps!
Answer:
C) phenotypic plasticity
Explanation:
- The ability of an organism to change phenotypically according to environmental conditions is known as <u>Phenotypic plasticity</u>.
Organisms might adjust their morphology and physiology to a better performance in environmental heterogeneity.
Generalists species might present a higher magnitude of phenotypic plasticity than specialist species.
- Sulfur-reduction bacteria are obligated anaerobic microorganisms, that are <u><em>metabolically versatile</em></u><u><em>. </em></u>They might grow either as heterotrophs using organic molecules or as autotrophs using hydrogen and carbon dioxide.
These bacteria are <u>notoriously adaptable</u> and <u>might be found in many different environments</u> (terrestrial and/or aquatics) where there is no oxygen due to aerobic decomposition of the organic matter.
<em>They can be found in anoxic sulfuric environments. In the soil, in estuaries mud, in freshwater, in sewage systems, salty waters, thermal water, sulfur deposits, in oil and gas wells, and even in animals and insects intestine</em>.
I don't have an answer, but your doing this in college, when I need this in my 6th grade earth science? dang lol
