Briefly, one can categorize the 3 types of boundaries as so: At convergent boundaries, the two tectonic plates are coming closer to each other; at divergent boundaries they are increasing they move away from each other and at transform boundaries the plates are moving parallel to their boundary. Based on this, all boundaries will be divergent boundaries.

Place the following steps of endomembrane system function in the correct order.
maks197457 [2]

Answer:

D

Explanation:

<em>The correct option here would be</em><em> D</em><em>.</em>

The endomembrane system refers to a group of membrane-based organelles whose primary function is to synergistically work together to modify, package, and transport lipids and proteins. The system includes organelles such as the lysosome, the nuclear envelope, the endoplasmic reticulum, and the Golgi apparatus.

For an endomembrane system function involving a protein, the protein would first of all need to be synthesized by the ribosome - the free ones or the ones attached to the rough endoplasmic reticulum. Thereafter, the synthesized protein would then be folded or packaged into transportable vesicles. The vesicles are then received by the Golgi apparatus which further modifies the proteins before transporting them accordingly.

Hence, the correct order of a typical endomembrane system function would be:

  1. <em>Ribosomes on the RER synthesize proteins.</em>
  2. <em>Proteins are packaged into transport vesicles.</em>
  3. <em>Golgi apparatus receives transport vesicles from the RER.</em>
  4. <em>Proteins are modified by the Golgi apparatus.</em>
  5. <em>Modified proteins may be secreted from the cell by exocytosis.</em>

The potential effects associated with the keystone species includes the following:

1. No other species will be capable of filling the same ecological niche. Hence, the dependent organisms will suffer and the ecosystem will change drastically.

2. The ecosystem will be populated by the invasive species which will affects the population of native species.
