The lac operon of E. coli contains genes involved in lactose metabolism. It's expressed only when lactose is present and glucose is absent.
<h3>How is the lac operon triggered by E. coli?</h3>
The lac operon of E. coli contains genes related to lactose metabolism. Only when lactose and glucose levels are low does it manifest symptoms. Two regulators that control the operon's "on" and "off" states in response to lactose and glucose concentrations are lac repressor and catabolite activator protein (CAP).
<h3>Why does E. coli prefer glucose to lactose?</h3>
Because it promotes quicker development than other sugars and is the first sugar to be consumed in sugar combinations, glucose is frequently the best carbon source for E. coli.

Answer:
In oxygenic photosynthesis, the first electron donor is water, creating oxygen as a waste product. In anoxygenic photosynthesis various electron donors are used. Cytochrome b6f and ATP synthase work together to create ATP. This process is called photophosphorylation, which occurs in two different ways.
Explanation:
Answer:
Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error).
Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations.
Genetic drift may result in the loss of some alleles (including beneficial ones) and the fixation.
Genetic drift can have major effects when a population is sharply reduced in size by a natural disaster (bottleneck effect) or when a small group splits off from the main population to found a colony (founder effect).
