Kush was the center of the iron trade in the ancient African world. To produce iron from ore, Kush needed to burn wood. Wood was running out. Kush had to turn their attention to other trade goods to survive. They had heard stories of the wonderful gold mines on the other side of Africa.
When is the earliest you can see a heartbeat on ultrasound? At about six weeks into pregnancy (four weeks from conception), you should be able to see your baby's heartbeat on ultrasound. The typical heart rate at this age is about 100 beats per minute. As your pregnancy progresses, your baby's average heartbeat will be between 120 and 160 beats per minute. Your doctor will not only be looking for a heartbeat, she will also be looking for a gestational sac. She will measure the size of the baby. This will help her to determine your baby's age.
A heartbeat should be visible via ultrasound by 6 weeks of pregnancy. At 7 weeks your baby has arm and leg buds. At 8 weeks, your baby starts moving around around and by 9 weeks your baby has 10 fingers and 10 toes. Between 10-12 weeks you should be able to hear your baby's heartbeat with a trans-abdominal doppler device. And at 12 weeks your baby can suck its thumb! posted 10/12/2010 by sugar&spiceX3.
