Fission refers to the division of a single organism into two or more equal organisms that resemble or are identical to the parent. This is one of many studies showing how poor stents are, and what a bad choice they are. The main potential benefits associated with anabolic steroids are the following ( 1 ): increases in muscle tissue due to enhanced protein synthesis. Lead is toxic mainly because it preferentially replaces other metals (e.g., zinc, calcium and iron) in biochemical reactions. When they sense suspicious activities, they can quickly contract by hiding their trumpets (or the crown of cilia) inside the body and run away.var cid='5391902911';var pid='ca-pub-2969755229433765';var slotId='div-gpt-ad-rsscience_com-box-3-0';var ffid=1;var alS=1002%1000;var container=document.getElementById(slotId);var ins=document.createElement('ins');ins.id=slotId+'-asloaded';ins.className='adsbygoogle ezasloaded';ins.dataset.adClient=pid;ins.dataset.adChannel=cid;ins.style.display='block';ins.style.minWidth=container.attributes.ezaw.value+'px';ins.style.width='100%';ins.style.height=container.attributes.ezah.value+'px';container.style.maxHeight=container.style.minHeight+'px';container.style.maxWidth=container.style.minWidth+'px';container.appendChild(ins);(adsbygoogle=window.adsbygoogle||[]).push({});window.ezoSTPixelAdd(slotId,'stat_source_id',44);window.ezoSTPixelAdd(slotId,'adsensetype',1);var lo=new MutationObserver(window.ezaslEvent);lo.observe(document.getElementById(slotId+'-asloaded'),{attributes:true}); [In this image] Anatomy of a Stentor coeruleus cell: (left) fully extended form; (right) contracted form.Photo credit: Current Biology.
