Answer:
The correct answer is - the cell membrane.
Explanation:
When a human cell gets an external stimulus it triggers the production of the specific compound or chemical release which is packed in vesicles from the endoplasmic reticulum and Golgi apparatus to the cell membrane. The cell membrane is the cell organelle that allows or prohibits the entry or exit of any substance.
Chemical release or secretion also depends on the cell membrane and it allows the secretion of chemicals and plays an important role in the secretion of chemical, hormones, or any substance.
Answer: The answer is BOUNDARY
Explanation:
Answer:
C. The results of a model event may not be similar enough to the results of the actual event.
Explanation:
The problem with models is that sometimes we trust them too much! Sometimes they are not accurate for long-term actual events. This is answer choice C.
- Models are never more accurate than reality, so rule out A.
- The model is based on our predictions of the actual event, so rule out B.
- The model being "too similar" to the actual event is what we want! So rule out D.
Introduced species
Ecosystems are complex systems that are in dynamic equilibrium with constant interactions between their parts.
When a new species is introduced, new interactions will occur, generating new components of the system and also competing with the previous interactions between the species already present in the system, which normally ends up generating an imbalance in the ecosystem mentioned, i.e a disruption in it.
