Which statement about analogies is correct?
they occur only as errors.
they are synonymous with homologous traits.
they are derived by similar environmental constraints.
they are a form of mutation.

The correct answer is C. They are derived by similar environmental constraints.

Explanation:

In biology, an analogy refers to two or more types of organism that have structures or behaviors with the same function but do not share a common ancestor which means the structures or behaviors that are similar or identical developed independently. This can be explained due to similar conditions or constraints in the environment that force organisms of different environments to evolve in the same way. This concept differs from homologous traits because in homologous there is not a similarity in function and they involve a common ancestor. Considering this, the correct statement is "they are derived by similar environmental constraints" because they occur due to similar adaptative situations.

clinically, some people often have repeated allergies, eczema and respiratory infections or other parts of the infection, in this case, in addition to some routine tests such as tests for white blood cells, immunoglobulin series, lymphocyte subsets, etc., the five immune immunoglobulin tests are also necessary.

answer: b: experiments that showed that all cells are similar in how they metabolize and in their composition
