2.4.1 Cell Activities \Packaged\ sequences (cascades) of cell activities/functions with an identifiable beginning and an end 2.4.1.1 Mitosis(Proliferation) Mitosis is a complex of processes leading to the division of a cell such that the two daughter nuclei receive identical complements of the number of chromosomes characteristic of the cells of the species. All cells arise from the division of pre-existing cells. The process of mitosis is divided into four phases:

TISSUE Tissue is a biological structure made up of cells of the same type. - Cells of the same phenotype(e., same genes expressed). An aggregation of morphologically similar cells and associated extracellular matrix acting together to perform one or more specific functions in the body. - There are four basic types of tissue: muscle, nerve, epithelia, and connective. An organ is a structure made up of or more tissues

随着科学技术发展,机械新概念、新理论、新方法、新工艺不断涌现,机械 正朝着高速、重载、高精度、高效率、低噪声的方向发展;机械的应用领域不断 扩大,机械学科与电子工程、计算机科学、控制工程、材料科学、生物医学相互 渗透,诞生了若干新学科,如机械电子学、仿生机械学、机器人机械学、机械 CAD等

本章描述X用来调整所谓‘文档准备系统的那些功能,而前面几章 主要着重于文本处理。修饰词‘高级’可能会有误导作用,因为这里只是指这 些功能对于高效地创建长而复杂的文录是相当重要的。这里的内容包括把 个文档分成几个文件,文档中不同部分的选择处理,章节、插图和公式的交 叉引用,自动生成参考文献、索引和汇总,处理不同的字体集合,准备报告 材料

蛋白质和核酸是生命现象的物质基础,是参与生物体内各种生物变化最重要的组分。蛋 白质存在于一切细胞中,它们是构成人体和动植物的基本材料,肌肉、毛发、皮肤、指甲、 血清、血红蛋白、神经、激素、酶等都是由不同蛋白质组成的。蛋白质在有机体中承担不同 的生理功能,它们供给肌体营养、输送氧气、防御疾病、控制代谢过程、传递遗传信息、负 责机械运动等。核酸分子携带着遗传信息,在生物的个体发育、生长、繁殖和遗传变异等生 命过程中起着极为重要的作用
