If B(t) represents the number of bacteria after t minutes, then B(t) = 200*2^(t/20).
There is no way to determine the amount of perfect numbers there are. The number could be infinite, but this has yet to be proven. It has also yet to be proven if there are any odd perfect numbers.
300,000,000 or Three hundred million (roughly the population of the USA).
First of all, to know if a number is abundant, deficient, or perfect, you need to know all the factors of your given number. The factors of 28 are 1,2,4,7,14, and 28. Add your proper factors -or the factors except itself- and determine if the sum of the proper factors is below (deficient), above (abundant), or the exact same amount (perfect). In this case, if you add the proper factors, it equals exactly 28. Because it is exact, it is perfect! =)
what kind of correlation would you expect to find between a city's annual and the size of its population
Well, isn't that a lovely question! 109 minutes is just a little under 2 hours. It's a perfect amount of time to sit back, relax, and maybe even paint a happy little tree or two.
The thick-walled structure in bacteria that contains the chromosome and a small amount of cytoplasm is called an endospore. Endospores are formed under stressful conditions such as nutrient deprivation to protect the bacterial DNA and ensure survival.
The rate at which a bacteria cell reproduces can vary depending on the species and environmental conditions. Some bacteria can replicate every 20 minutes under optimal conditions, while others may have longer replication times. In general, bacteria can reproduce multiple times in a day if conditions are favorable.
Pasteurisation does not kill all bacteria in the milk. Some bacteria are not killed in the heating process and will start to multiply again after pasteurisation. Cooling after pasteurisation is needed in order to limit the amount of bacterial growth that occurs. Bacteria reproduce very slowly in cold conditions, but very quickly in hot conditions. Cooling is the only preservative that is used after pasteurisation.
Studies have shown that money can harbor thousands of different types of bacteria, some of which may be harmful. The amount of bacteria on money can vary depending on factors such as usage and storage conditions. Regularly washing hands after handling money can help reduce the risk of transferring bacteria.
linear growth is the equal growth in a equal time period without any aspects such as food to change it. Exponential growth is the growth of the population based on the culmulative things in the environment affecting the population of the area
to know the amount of bacteria present
Nutrients: Bacteria need sources of carbon, nitrogen, and other essential nutrients for growth. Moisture: Bacteria require a certain level of water to function and reproduce. pH level: Bacteria thrive within specific pH ranges, with most preferring near-neutral conditions. Temperature: Bacteria have optimal temperature ranges for multiplication. Oxygen: Some bacteria need oxygen to multiply (aerobic), while others can grow in its absence (anaerobic). Time: Bacteria need a certain amount of time to go through their growth and division cycles.
the aerobic bacteria showed him the amount of oxygen produced since aerobic requires oxygen. the more bacteria produced, the more oxygen there had to have been, which means photosynthesis occurred the fastest where there was the greatest amount of bacteria.
the amount of bacteria on Earth would have to be at least over 100.

abiotic
It increases the chance that some members of the population will survive under changing environmental conditions.
