The elodea cells...................................................................
<span>A cell can die in many ways - through infection, poisoning, overheating or lack of oxygen. An uncontrolled death is messy: the cell swells up, and its contents leak away. This may damage surrounding cells. But there is another, tidier way to go - programmed self-destruction, or apoptosis.</span>
I think False ..........................................
<span>In liver, the most intensively studied transmembrane and intracellular signal transduction pathways are the Janus kinase signal transduction pathway, the mitogen-activated protein kinases signal transduction pathway, the transforming growth factor β signal transduction pathway, the tumor necrosis factor α signal transduction pathway and the recently discovered sphingolipid signal transduction pathway. All of them are activated by many different cytokines and growth factors. They regulate specific cell mechanisms such as hepatocytes proliferation, growth, differentiation, adhesion, apoptosis, and synthesis and degradation of the extracellular matrix. The replication cycle of hepatitis C virus (HCV) is intracellular and requires signal </span>
