inessss [21]

Answer:

negative, inhibition

Explanation:

The experiment in the illustration shows that early succession plants have a <u>negative </u>effect on the late succession plants, and the observation is most consistent with the <u>inhibition</u> model of succession.

<em>That the late succession plant thrives better in the absence of the early succession plants means that the early succession plant has been impacting the growth of the late succession plant negatively. This is consistent with the inhibition model of succession.</em>

There are 3 different models of succession. These include;

  1. Facilitation model in which colonists modify the environment to favor the growth of later successional species.
  2. Tolerance model in which early colonists' modification of the environment has no positive or negative impact on the growth of later successional species.
  3. Inhibition model in which early colonists modify the environment to inhibit the growth of later successional species.

The broadest way to classify the nervous system is to differentiate between the ______ nervous systems.
ankoles [38]

Answer:

Central and Peripheral

Explanation:

The nervous system is divided into two parts: the central nervous system and the peripheral nervous system. The central nervous system includes the brain and spinal cord.

On the other hand the peripheral nervous system includes all of the nerves that branch out from the brain and spinal cord and extend to other parts of the body including muscles and organs. Each part of the system plays a vital role in how information is communicated throughout the body.

The below diagram provides a schematic view of the role of each sub-division  of the Nervous System.
