Penjelasan
The question pertains to the behavior of erythrocytes (red blood cells) in different osmotic conditions. The terms "lysis" and "crenation" are key to understanding the phenomena being described. Lysis occurs when a cell bursts due to an influx of water, which happens in a hypotonic solution where the external solution has a lower concentration of solutes than the cell's interior. Crenation, on the other hand, occurs when a cell shrinks due to water leaving the cell, which happens in a hypertonic solution where the external solution has a higher concentration of solutes than the cell's interior.
1. Option (A) suggests that lysis occurs because the cell's interior has a higher concentration than the outside solution. This is consistent with a hypotonic environment, leading to lysis.
2. Option (B) suggests crenation due to the external solution entering the cell. This is not a typical description of crenation, which occurs due to water leaving the cell, not entering it.
3. The third option (not labeled, but following B) suggests lysis due to the cell's fluid leaving the cell. This is incorrect as lysis occurs due to water entering, not leaving the cell.
4. Option (D) suggests crenation occurs because the external solution has a lower concentration than the cell's interior. This is incorrect as crenation occurs in hypertonic solutions where the external solution has a higher concentration.
5. Option (E) suggests crenation occurs when the external solution has the same concentration as the cell's interior. This is incorrect as crenation occurs in hypertonic solutions, and an isotonic solution (where concentrations are equal) would not cause crenation or lysis.
Based on this analysis, the correct answer is the one that accurately describes the condition leading to lysis, which is a hypotonic environment where the external solution has a lower concentration of solutes than the cell's interior.
