It has been suggested that the cells of living organisms are functioning in a near chaotic regime called critical, which offers a tradeoff between stability and evolvability. Abstract models for regulatory networks such as Kauffman's Random Boolean Networks certainly point in that direction. In this...
根据第一段“All living organisms are uniquely adapted to the environment in which they live. Scientists are studying the design and the biological processes of these organisms to get ideas for products and technologies. This field of study is called biomimetics. Here are two examples.(所有的生物...

1. All Living Organisms Are Composed Of Cells The first postulate of cell theory states something that we all find pretty obvious today—all living organisms are made of cells. However, if you look back a few hundred years ago, researchers had a hard time explaining this simple concept to ...
Without cells, living things would not be able to carry out essential functions such as reproduction, growth, and response to stimuli. Therefore, cells are the fundamental building blocks of all living organisms. Rate this question: 10. In multicelluar organisms, cells perform different ___....
The theory of evolution suggests that all living organisms are related through a process of: A. Common descent B. Independent creation C. Random development D. Spontaneous generation 相关知识点: 试题来源: 解析 A。本题考查进化理论的核心概念。共同祖先(Common descent)是进化理论的重要观点,即所有...
Xenobots straddle an unusual line. Are they living organisms or robots? They are organisms because they are made of stem cells and can reproduce. But they are also robots because they can move on their own and perform physical labor, co-author Sam Kriegman told The Washington Post. ...
