Why would a mutation in a somatic cell of a multicellular organism escape detection?
Mashcka [7]

When a somatic cell is mutated, none of the other cells in the organism mutate with it. Screenings usually detect mutations that are in numerous cells and not in just one. That is why a mutation in a somatic cell of a multicellular organism escape detection.

<h3>What are mutations?</h3>

A mutation in biology is an adjustment to the nucleic acid sequence of an organism's, virus's, or extrachromosomal DNA. DNA or RNA can be found in the viral genome. Errors in DNA replication, viral replication, mitosis, meiosis, or other types of DNA damage (such as pyrimidine dimers from exposure to ultraviolet radiation) can result in mutations.

These errors can then lead to error-prone repairs, particularly microhomology-mediated end joining, error-causing repairs, or errors during replication. Due to mobile genetic elements, mutations can also result from the insertion or deletion of DNA segment.

How do chemoautrophs make energy?
Mandarinka [93]

Answer:

hemotrophs are organisms that obtain energy by the oxidation of electron donors in their environment. Chemoautotrophs use inorganic energy sources to synthesize organic compounds from carbon dioxide. Chemoheterotrophs are unable to utilize carbon dioxide to form their own organic compounds.
