Coleman hypothesized that the product of the ob+ gene was the appetite-suppressing hormone. Therefore, the homozygous ob/ob mutant would be unable to synthesize that hormone, and its circulating level would be zero. Coleman also hypothesized that the product of the db+ gene was the the receptor for the appetite-suppressing hormone. Therefore, the homozygous db?db mutant would be able to respond to it. It would eat excessively and produce large amounts of body fat, which in turn would produce large amounts of appetite-suppressing hormone. In the absence of a receptor, the db/db mutant's hormone level would remain abnormally high.
Both the ob/ob mutant and the db/db mutant are obese because neither is capable of suppressing its appetite. The ob/ob mutant produces no appetite suppressing hormone and so eats excessively. The db/db mutant cannot respond to the appetite-suppressing hormone and therefore eats excessively.
Answer:
Isn't it ice cream..It has the most in the pie graph.
Sorry if I'm wrong, ice cream just makes the most sense.
Have a good day!
Explanation:
Answer:
The study of microbes in their natural habitat and their relationship with each other and their environment is termed as Microbial ecology. It mainly constitutes of Viruses, Eukaryotes ,Bacteria and Archaea as its living entities.
Being omnipresent in the biosphere they impact the other life-forms up to a significant extent.
They also help maintaining biogeochemical cycle by nitrogen fixation, sulfur metabolism and methane metabolism. Microbes also play a vital role of availing energy in the ecosystems where sunlight is scarce and hence photosynthesis is not good means of energy trapping, in such ecosystems the microbes actively engage in fundamental ecological processes including production, decomposition, and fixation inside the host organism.
Answer:
Autotrophs, but not heterotrophs, can nourish themselves beginning with and other nutrients that are inorganic.
Explanation:
Unlike heterotrophs, autotrophs such as green plants, are able to synthesize their food (in form of sugar molecules) starting with inorganic molecules like atmospheric carbon dioxide, water in the presence of sunlight.
This is commonly known as photosynthesis. The equation is shown below
6CO2 + 6H2O --> C6H12O6 + 6O2 + Energy
Ok so theirs this thing called asking your teacher for help especially when it’s such an easy question
