(1)水稻体内具有发达的气道体现了生物能
(2)稻谷中的淀粉被食用后,在小肠内最终分解为
(3)稻谷晒干后贮藏,这是为了抑制其
(4)水稻有高茎,也有矮茎。科研人员用高茎水稻和矮茎水稻进行遗传实验,结果如下图:
由实验二可以判断水稻的

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
