Instead, its defense responses end up being so inadequate that they actually contribute to the development of asthma.
Explanation:
Develop from a single fertilized egg and have identical genes.
Carbonate groups contain a single carbon atom, and three oxygen atoms in a trigonal molecular geometry. The carbon atom has two single bonds to two oxygen atoms and a double bond to the third oxygen atom. Therefore, in addition to carbon, carbonate minerals contain oxygen. An example of a carbonate mineral is calcium carbonate, often found within rocks.
