Sometimes 120 volts is referred to as 110 volts or 115 volts and 240 volts as 220 volts or 230 volts. As a central vacuum manufacturer we use the 120 and 240 volt motors, not the 110 or 220 volt ones. The 120 and 240 motors will not be adversely affected if used with lower voltages.The 120 volt motor will be fine on a 110 volts. And a 240 volt motor will be fine on 220 or 230 volts. But not the other way around. A 220 volt motor would be damaged if used for long periods of time on a 240 volt circuit.And the same for a 110 volt motor running on 120 volts.s a central vacuum manufacturer we use the 120 and 240 volt motors, not the 110 or 220 volt ones. The 120 and 240 motors will not be adversely affected if used with lower voltages. The 120 volt motor will be fine on a 110 volts. And a 240 volt motor will be fine on 220 or 230 volts.

In the last few weeks of the first trimester, the embryo really starts to take shape. The facial structures begin to form and become recognizable. The neural tube, which will form the brain and spinal cord, develops. Little buds emerge and grow into arms and legs. Around week 8, the embryo becomes a fetus. The kidneys, liver, brain, and lungs are all beginning to function. The fingers and toes are separate and the external genitalia are formed. At 12 weeks, the fetus is about three inches long and weighs about one ounce.
Share to: The difference between a embryo and a fetus is that the fetus is a fully developed embryo and a embryo takes up to 8 weeks to develop into a fetus    An embryo is a ferti â¦ lized egg that turns into a fetus at 8 weeks.nce the zygote becomes an embryo it starts developing all of its organs, nervous system etc. then after 8 weeks of development everything is there so it becomes a fetus, and â¦ the fetus just grows bigger.
