Answer:
The correct answer is: Uncontrolled release of digestive enzymes into the duodenum.
Explanation:
- SER or the Smooth Endoplasmic Reticulum is the major location in the cells where fatty acids and steroid molecules are produced.
- These fatty acid molecules form the structure of the various membranes in the cell, including the plasma membrane and organelle membrane.
- The membrane system of the cells gives them a structural integrity.
- Disruption of the SER of the pancreatic acinar cells by a toxin will prevent the synthesis of lipid molecules which forms the membranes in the cell.
- This will cause the membrane to lose its integrity, fluidity, flexibility and the ability to prevent unregulated movement of molecules across them.
- The digestive enzymes need to secreted by the pancreatic acinar cells into the duodenum only when food is available in the duodenum for digestion.
- But loss of the ability of the plasma membrane of the pancreatic acinar cells to regulate the flow of molecules across itself (due to disruption in the lipid production by SER) causes the unregulated flow of digestive enzymes out of the cells into the duodenum as soon as they get produced.
Answer:
A common and well-known example of a missense mutation is sickle-cell anemia, a blood disease. People with sickle-cell anemia have a missense mutation at a single point in the DNA. This missense mutation calls for a different amino acid, and affects the overall shape of the protein produced.

I would have to say A. Fell free to correct me if i'm wrong :)
Answer:
Species become endangered for two main reasons: loss of habitat and loss of genetic variation. A loss of habitat can happen naturally. ... Human activity can also contribute to a loss of habitat. Development for housing, industry, and agriculture reduces the habitat of native organisms
