Answer:
After a cell was treated with a certain chemical, the ribosomes stopped functioning. The cell activity immediately affected by this change in ribosome function is protein synthesis.
Explanation:
The basic structural units of all living things are known as cells. Inside the cells, specialized structures called ribosomes are present, which synthesize proteins. The protein synthesis in a eukaryotic cell consists of two processes, transcription and translation.
The transcription process takes place in nucleus, where the information from a DNA strand is copied into a single stranded messenger RNA (mRNA) molecule using RNA polymerase enzyme. During the ending of transcription, the completed mRNA strand detaches from DNA and exits the nucleus and goes into a ribosome in the cytoplasm. In the ribosome, translation occurs where the genetic code in mRNA is read and protein is synthesized. These proteins are used by cells to perform important functions such as repairing cellular damage, maintain cellular structure, create hormones, cell division etc.

Answer:
No, not all genetic change is adaptive.
Explanation:
This is because genetic changes happen in many ways and this can be adaptive or not.
The main form of genetic change happens through genetic mutations, and these mutations are not always adaptive.
One might think, for example, of a river polluted with a chemical reagent that causes mutations in the scale genes of the local fish population, mildly damaging the way they swim. Despite being a nonadaptive genetic change of fish, they have continued to reproduce so that this change is part of their population.
Although this happens, it is important to note that this rarely happens. Since natural selection ends up selecting the most suitable in the long run.
