Answer:
C. They are carried by motor proteins using the cytoskeleton as a "roadway"
Explanation:
Vesicles hitch a ride on molecular motors such as kinesin or myosin, moving along the cytoskeleton until they reach their intended location, where they then fuse with the target membrane or organelle. Typically, vesicles progress from the ER to the cis Golgi, followed by movement from the cis to the medial Golgi, from the medial to the trans Golgi, and finally from the trans Golgi to the plasma membrane or other cellular compartments. While the predominant direction is forward, there are also vesicles that return from the Golgi to the ER, carrying proteins that should have remained in the ER (e.g., PDI) that were inadvertently enclosed in a vesicle.
Answer:
A. The ecosystem absorbs significant rainfall, aiding in flood prevention.
C. At times throughout the year, water may either saturate the soil or remain just beneath its surface.
D. It might be classified as a freshwater bog, swamp, or marsh.
Explanation:
Answer B is the only one that stands out from the rest, as it directly pertains to a river.
I believe the correct answer is D.
My reasoning for this conclusion is that coyotes from various groups would have encountered diseases and potentially developed immunity (for those that survived), allowing them to migrate to other coyote populations where those individuals may introduce the illness.
Answer:
The pathway likely taken is ER - Golgi - vesicles that merge with the plasma membrane.
Explanation:
The endomembrane system comprises a complex network of internal membranes. It was first identified in the late 19th century when Camillo Golgi observed that a specific stain selectively colored certain cellular membranes. Golgi believed these membranes were interconnected; however, subsequent developments in microscopy and biochemical analysis revealed that the organelles within the endomembrane system function as distinct compartments with specialized roles.
