← Nature & AnimalsWhich outcome occurs to fish embryos when low oxygen?
A)Decreased oxygen diffusing from water✓
B)Increased active transport in cells
C)Elevated metabolism within the egg
D)Faster, uncontrolled cell mitosis
💡 Explanation
Decreased oxygen diffused due to lack of the countercurrent exchange mechanism in fish eggs because the concentration gradient decreases, causing reduced efficiency of oxygen absorption rather than other cellular processes responding effectively, therefore diffusion fails in low oxygen.
