Answer: One of the most common Monera is Escherichia coli, also known as E. coli. "[E. coli] is a Gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms." States wikipedia.* Signs of E. coli are stomach pains and cramps, diarrhea that may range from watery to bloody, fatigue, loss of appetite or nausea, vomiting, and low fever < 101 °F/ 38.5 °C (not all people have this specific symptom).
E. coli comes from human and animal wastes. During precipitation, E. coli may be washed into creeks, rivers, streams, lakes, or groundwater. Another way to get it is from contaminated food, a lot like corona virus. When cattle are slaughtered and processed, E. coli bacteria in their intestines can get on the meat. And when ground beef is made, it combines meat from many different animals, increasing the risk of contamination.
Explanation:
It is true that it is possible for a population to not evolve for a while.
There is something called the Hardy-Weinberg theorem, which characterizes the distributions of genotype frequencies in populations that are not evolving.
There are 5 Hardy-Weinberg assumptions:
- no mutation
- random mating
- no gene flow
- infinite population size
- and no selection (natural nor forced).
You can see that some of these are kinda extreme and really hard to get, but with approximations, we can work.
For example, instead of an "infinite population size" we have enough with a really large population, such that genetic drift is negligible.
Concluding, yes, it is possible (but really difficult) for a population to not evolve for a while (at least, in nature), as long as the 5 assumptions above are met.

Answer: If the temperature increases, then the activity of the lions decreases.
In two species of birds, both of which form monogamous pair(one male and one female), In species 1, you find that the eggs in a pair's nest are in fact almost always the offspring of that pair. In species 2, you are surprised to find that many of the eggs in a nest were actually fathered by males of neighboring pairs. Apparently, mating outside of monogamous pairings is widespread in species 2. we would expect that female of species 2 would have sperm from multiple males in their reproductive tracts.
- This is because the species 2 are having many eggs.
- These eggs were formed due to fertilization with multiple male bird partners.
- As a result we can expect eggs with different genotypes.
Thus from the above points we can conclude that two species of birds, both of which form monogamous pairs, female of species 2 would have sperm from multiple males in their reproductive tracts
