1) Os íons sódio (Na+) e potássio (K+), são essenciais para o funcionamento da célula, atuando no funcionamento muscular e também na sinapse química que ocorre entre neurônios. Um estudo desenvolvido por pesquisadores de uma universidade revelou as seguintes medidas destes íons no interior de neurônios gigantes de lula: [ Na+ ] no citoplasma = 50
[ Na+ ] no meio extracelular = 440
[K+] no citoplasma = 400
[K+] no meio extracelular = 20​

After reading the paragraph below, answer the questions that follow. researchers have created a robot that has a very thin leg that is moved by cardiac (heart) cells contracting in unison. the robot, made of a polymer similar to that used in making contact lenses, is bathed in heart cells with supporting cells, which then attach to the robot and provide movement as they contract. all of the cardiac cells working together can cause the robot leg to move in a way that individual cells could not. this is an example of a. emergent properties of cells. b. energy flow through an ecosystem. c. adaptation. d. internal environment regulation.
