A.甲组NaCl处理不能引起细胞发生质壁分离,表明细胞中NaCl浓度≥0.3 mol/L |
B.乙、丙组NaCl处理皆使细胞质壁分离,处理解除后细胞即可发生质壁分离复原 |
C.该菌的正常生长和吸水都可导致原生质体表面积增加 |
D.若将该菌先65℃水浴灭活后,再用 NaCl溶液处理,原生质体表面积无变化 |

y = sin x, x∈R, y∈[–1,1],周期为2π,函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x, x∈[–1,1], y∈[–π/2,π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
