Answer:

(1) normally harmless cat antigens stimulated

the immune system

Explanation:

It isn't the fault of the respiratory system that the antigens produces an immune response to cat antigens but the specific genotype of the child. The genotype has developed his immune system too much sensitive mostly due to an anomaly or mutation. Now, normally harmless antigen will produce a immune response because it has enough potential of activation for induction of an immune response.

alekssr [168]

Answer:

The correct answer will be- homologous structures

Explanation:

The history of how life has survived on the earth can be studied through a field of biology called evolutionary biology.

Studying the anatomical features of the organisms and the collected specimens (fossils) shows that some organisms posses similar anatomical structures which could be performing different functions.

The structures in organisms which are similar in their structure are thought to have derived from a common ancestor and are known as "homologous structures. "

Thus, homologous structures are the correct answer.
