将胃癌细胞分散成单个细胞能用胃蛋白酶吗

吃刺激性的食物、暴饮暴食后出现胃病,不处理后,久而久之就有可能得胃癌.

Hi!Dear Uncle,
How are you doing recently?You should to take care of yourself!
My mother was seriously ill in the hospital for stomach cancer.She wants to see you for last time,we hope you can come back as soon as possible.

解题思路：该实验研究雪灵芝提取物对人胃癌细胞增殖的影响，自变量为雪灵芝提取物的浓度，因变量为胃癌细胞周期各期细胞百分比．

A、随着雪灵芝提取物的浓度升高，处于G₁期的细胞比例增大，处于S期的细胞比例下降，可知雪灵芝提取物可阻止胃癌细胞从G₁期进入S期，A正确；
B、用高倍显微镜不能观察的细胞的细胞膜，所以糖蛋白也观察不到，B错误；
C、四组实验中c组胃癌细胞G₂+M时间最长，不能说分裂期持续时间最长，C错误；
D、四组实验中，随着雪灵芝提取物的浓度升高，处于S期的细胞比例一直下降，没有出现上升，所以不能说d组雪灵芝提取物浓度为抑制胃癌细胞增殖最适浓度，D错误．
故选：A．

点评：
本题考点： 恶性肿瘤的防治；癌细胞的主要特征．

考点点评： 做本题的关键是找准自变量与因变量，以及会获取信息、处理信息．
