Simple use property 'visible':

<mx:RadioButtonGroup id="radioGroup"/>
<mx:RadioButton id="radioYes"
        groupName="{radioGroup}" value="Yes" selected="true"/>
<mx:RadioButton id="radioNo"
        groupName="{radioGroup}" value="No"/>

<mx:Label text="First text"/>
<mx:TextArea id="textOne"
        visible="{radioNo.selected}"/>
<mx:Label text="Second text"/>
<mx:TextArea id="textTwo"
        visible="{radioNo.selected}" includeInLayout="{radioNo.selected}"/>
<mx:Button id="btnContinue"
        label="Continue"/>

Please take attention at property 'includeInLayout'. In my solution one text area is hidden and takes no place, another one is hidden, but keeps reserved place.
