1. the chart below shows information about the relationship between the age of the mother and the occurrence of down syndrome in the child.

age of mother	occurrence of down syndrome per 1000 births
30	1.0
35	3.0
40	10.0
45	30.0
50	80.0

if a mother has a child later in life, her children may be impacted. describe evidence from the graph that supports the claim.

Explanation:

To support the claim that having a child later in life impacts children (in terms of Down syndrome occurrence), we analyze the table: as the mother's age increases (from 25 to 50), the occurrence of Down syndrome per 1000 births rises. At 25, it's 0.8; at 30, 1.0; 35, 3.0; 40, 10.0; 45, 30.0; 50, 80.0. This shows a clear upward trend with increasing maternal age, indicating later childbearing is associated with higher Down syndrome occurrence.

Answer:

As the mother's age increases (e.g., from 25 to 50), the occurrence of Down syndrome per 1000 births rises (0.8 at 25, 1.0 at 30, 3.0 at 35, 10.0 at 40, 30.0 at 45, 80.0 at 50). This upward trend with maternal age supports that having a child later in life is associated with a higher risk of Down syndrome in the child.
