Fossil record- species evolve differently in different environments . different species evolve similarly in the same type of environment
homologous structures of living organisms- 2 variations; similar body structures that don't necessarily have similar functions
homologous- diff mature forms but develop from embryonic tissues
vestigial- similar structures with reduced size and lesser or no functions
embryology- early stages of many animals are very similar- suggesting that organisms share common ancestry
The food web would be likely destroyed because one animal will not have nothing to eat out of the food we’d and then that’s how the food web will be messed up
Answer:
An allergic reaction
Explanation:
An allergic reaction occurs when our immune system misinterprets a harmless substance into a harmful antigen and initiate an over-expressed immune response against it. Some of these allergic substances are pollen, molds, insect stings, etc.
These allergens trigger the production of IgE antibodies in the body which interact with different cell and initiate the release of chemicals like histamine that cause symptoms of allergic reaction.
It can affect the nose, skin, lung, stomach lining, etc. Therefore the correct answer is an allergic reaction.
