Because the vasculary bundles are sectioned and sieve can't pass through to feed the organs of the plant.
Explanation:
With time bacteria cells increase in number, exponentially. This means with each generation, the population doubles. An example is that if initially there were 2 bacteria, they become 4, then 16, then 32, then 64, 128, then 256...etcetera. Remember bacteria can double their population in very short times. E. Coli cells double in the lab in 15 – 20 minutes.
However, bacteria are also subject to limiting factors that do not allow their cells to double indefinitely, resources such as space and nutrients limiting growth rates for bacteria especially when their numbers exceed the carrying capacity of their environment.

Answer:
D. physiological mechanisms are the basis of behaviors.
Explanation:
The example of the development of electric fields as part of the communication between some fish, shows the interrelation that exists between physiology and behavior. This physiological factor that fish have has an impact on their behavior. However, it is necessary to recognize that physiology does not act by itself, but needs to receive a stimulus from the surrounding environment.
This way of communicating is called electrocommunication, a fish generates through its physiology an electric field and a second individual receives that electric field with its electroreceptors.
Science uses data to describe the findings of an experiment, qualitative data is: set of data describing the findings of an experiment.
Qualitative data is data that describes, analyzes, decodes, translates, and synthesizes the results of events that occur more or less naturally.
It tries to achieve a holistic description, that is, it tries to exhaustively analyze, in great detail, the findings of an experiment.
It contains the narrative records of the findings of an experiment studied through techniques such as participant observation and unstructured interviews.
That is, the analysis of qualitative data is mainly one of synthesis and integration of the information obtained from various instruments and means of observation.
That is,a coherent descriptive analysis that aims to achieve a thorough and detailed interpretation of the research problem will predominate.
Therefore, we can conclude that qualitative data is the set of data describing the findings of an experiment.
