A jar contains a bacterium which doubles every minuteThe jar was full at the end of 3 hoursHow long will it take ot filll 25 percent of the jar?
That depends a great deal on how you define the term "multiply". If you mean each cell divides - doubling the number of bacteria, the it would be half full at 11:59 PM and double to twice that 1 minute later at 12 AM, i.e. 2 x ½ = 1 (12 AM is midnight - see the discussion below) . Of course if by 12 AM you meant Noon - then the answer would be 11:59 AM.
If the multiplication factor is other than 2, the answer would have to be modified accordingly.
Convention has it that 12 midnight is called 12 AM, which comes after 11:59:59 pm, and thus the day starts with am. In other words the date in the calendar change at midnight and that moment is called 12 AM.
You could, of course , use a different system to avoid this confusion such as the 24-hour clock. There, the beginning of the day (12 AM or 12 midnight) is denoted by 0000 hours, and the last minute of the day starts at 2359 hours (equivalent to 11:59 pm). So the time after noon is denoted by numbers from which 1200 should be subtracted to get the time as per 12-hour clock.

If a certain bacterium divides every 30 min when will there be more than 1000 bacteria?
After 4 hours, as the bacterium doubles every 30 minutes, resulting in 8 divisions within this time frame. Starting with 1 bacterium, this will lead to 28 = 256 bacteria after 4 hours.
How many bacterium are in the sixth generation?
The number of bacteria in the sixth generation of a bacterial population depends on the initial number of bacteria, as each generation doubles the population. If the initial number is 1 bacterium, the sixth generation would have 32 bacteria (2^6).
If there was one bacteria on a piece of meat left in a nice warm place for five hours how many would be present at the end of this time?
Bacteria breed at different rates.The answer to your question would depend on what the bacterium was. IF we could assume that it is a bacteria that doubles every 20 minutes under these particular conditions, 1 bacterium would turn into 214 or 16384 bacteria. Again, realize that growth rates will vary and, when it comes to food, you almost never start out with only one bacterium.
What happens in a cell interphase?
The cell grows, and develops, as it doubles its size. It contains DNA structures now, called chromosomes.
What simple machines are in an esculator?

Can you have doubles play in tennis?
Yes. Mens Doubles, Ladies Doubles and Mixed Doubles are permitted forms of Doubles in Tennis.
What kind of growth does a population of bacteria experience when jus a few of them are placed in an environment rich with resources?
The population will experience exponential growth as the bacteria reproduce rapidly in the resource-rich environment. This is known as the exponential phase of growth, where the number of bacteria doubles in a relatively short period of time due to abundant resources available for growth and reproduction.
