Default network


When the brain is unoccupied, an fMRI indicates that blood continues to flow via a web of brain regions called the default network.

The default network is a web of brain regions that have activity that corresponds greatly with each other and different from other networks within the brain. The default network is active when an individual's attention is not concentrated on the external environment and it is measured with the functional magnetic resonance imaging technique (fMRI).

When can exponential growth happen?
Anna007 [38]

Answer:

The correct answer is option A, when there are unlimited resources

Explanation:

In an exponential growth, the size of population increases with a tremendous rate as there is no competition for resources among the species. A common example of exponential growth can be of bacteria, whose population increases tremendously in unlimited supply of nutrients. The exponential growth can be mathematically represented as  

dN/dT=rmaxN  

where r max = maximal growth rate for a species  

N = population of a species

Choose the phase of the bacterial growth curve during which a bacterial population has the briefest doubling time.
Scrat [10]
The stage where the doubling time will be the shortest will be the one where replication is taking place the fastest. This phase is known as the exponential phase. This phase is characterized by exponential growth rates of a bacterial colony.

This phase occurs due the excess amount of resources that are present compared to the amount necessary to sustain the bacterial colony. Therefore, not being limited by resources, the bacteria multiply rapidly. However, the resources then run out due to which replication stop, bringing on the lag phase. Finally, the bacteria begin to starve and die off due to the lack of resources, bringing about the death phase.
