State the names of two hormones released by the ovaries. During pregnancy, antibodies are acquired by the fetus from the mother. State the organ the antibodies cross to reach the fetus. A baby was breastfed for six months. The concentration of antibodies in the baby’s blood obtained from breast milk and the concentration of antibodies made by the baby itself were measured. shows the results. age of the baby / months breastfeeding stopped concentration of antibodies in the baby’s blood / arbitrary units Key: antibodies acquired by the baby from the mother antibodies produced by the baby Complete the sentences to describe the changes in antibody concentration in the baby. After birth the concentration of antibodies acquired from the mother decreases rapidly to 0 arbitrary units at months. Antibodies start being produced by cells called in the baby immediately after birth. The total concentration of antibodies in the baby from both sources is arbitrary units at 4 months. The concentration of antibodies acquired from the mother and the concentration of antibodies produced by the baby are the same at months. Describe the benefits of breastfeeding a baby for the first six months of life. State two ways, other than breastfeeding, that a baby can acquire immunity. Explain the importance of the shape of an antibody. Antibodies are proteins. State the chemical elements present in all proteins that are also found in carbohydrates and fats.
