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.

Ksivusya [100]

Answer:

This statement is true

Explanation:

Technologies associated with agriculture systems have greatly enhanced crop yields around the world. An example of this is the "Green revolution" in 1950-1960, where the combination of genetic improvement methodologies with the use of fertilizers was critical for the amazing increase in crop yields, particularly in new varieties of rice and wheat. Indeed, the agronomist who developed some of these high yielding varieties of wheat, Norman Borlaug, was awarded the Nobel Peace Prize for his contribution to the extensive increase in crop production, thereby helping to alleviate world hunger.

Which statement represents the correct association of organisms and their habitat? Each organism will be found in only one habit
AleksandrR [38]
<span>The correct answer is Some plant and animals are restricted to a particular habitat. That means that they would not be able to live in other habitats either because of natural predators that would eliminate them or because they would ruin the ecological system if they were to interfere with the natural order of things. Things like climate might also affect this.</span>
