Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).

Molecular biology. DNA and the genetic code reflect the shared ancestry of life.  

Biogeography.  

Fossils

Biogeographical evidence, fossil evidence, and anatomical evidence are three pieces of evidence to support the theory of evolution.

What is evolution?

Evolution states the changes observed in organisms over time, this makes benefits the organism for its survival.

Anatomical evidence, support the theory of evolution, by comparing the anatomical structure of related species. Fossil evidence also provides evidence that how organisms evolve from the ancestor species.

Biogeographical evidence provides major clues about the relation between extinct and alive species, this benefits the theory of evolution. All this evidence supports the life formation around the earth and the relationship between organisms.

Therefore, biogeographical evidence, fossil evidence, and anatomical evidence support evolution.

Why Is DNA important for protein synthesis?

Answers

Answer:

The most important function of DNA is its ability to replicate itself repeatedly.

Explanation:

DNA makes RNA makes Protein. As you have learned, DNA is the genetic material of your cells and holds the information for making all the different proteins of your body. ... Translation converts the information in a series of three letter words in the mRNA into a sequence of amino acids, the building blocks of proteins.

DNA is important for protein synthesis because it holds all the genetic information necessary to synthesize all proteins of the cells that it required.

What do you mean by Protein synthesis?

Protein synthesis may be defined as the process by which cells make proteins that are required for their metabolism and function.

DNA is the primary genetic material contained in the cell of all organisms. It is used to create proteins during protein synthesis because central dogma reveals the importance of DNA in the process of protein synthesis. DNA is considered the root of the central dogma.  

Therefore, DNA is important for protein synthesis because it holds all the genetic information necessary to synthesize all proteins of the cells that it required.

Making a promise is a commitment that you will keep your word therefore, it could reinforce trust within the connections you have with the people you care for. Keeping promises is important because it helps build better relationships with the people around you. When you keep a promise it can show that you are a reliable and trustworthy person. If you maintain a promise it can strengthen the mutual trust between you and the other person. For example, your Mom asks you to go to the store and you promise her that you will go.
