MariettaO [177]

Answer:

Organism D.

Explanation:

Amino acids are the monomers of proteins and are linked together by the peptide bond. The protein is obtained from the RNA molecules by the process known as translation.

The amino acid sequence of the proteins can also be used to study the evolutionary relationship between the organisms and the closeness of teh organisms with each other. In the question it is give that organisms A and D has least difference ( 1 amino acid sequence difference) and more related with each other.

Thus, the answer is organism D.

2. How does a universal genetic code relate to the hypotheses about the origin of life on Earth?
Minchanka [31]

The designated "universal genetic code" is the complex information system contained within DNA and is unique to every species and overall similar within all organisms.

There is no remaining DNA from the earliest organisms, but there is every evidence that all organisms that exist or have ever existed utilize DNA as the basis of the universal genetic code that configures life and regulates evolution.

Evolution does not occur without replication and replication does not occur without DNA. The structure of all organisms is protein based, which are virtually all specified by DNA, which itself is made up of proteins. A serious chicken and egg conundrum.

Present hypotheses about the origin of life, OoL, are restricted to purely natural conditions and causes for OoL because of the ideological belief called philosophical naturalism, but tis cannot explain the origin of DNA.

DNA is multi-level organically coded, intelligently designed and irreducibly complex, homochiral structured, most complex information in the universe, bar none. It has no natural process explanation. It is the basis for all evolution and the common design of all organisms.

Current naturalistic propositions about OoL will never find the source of OoL or explain the creation of DNA.

What happens when fluid is heated​
Crazy boy [7]

When heat is added to a substance, the molecules and atoms vibrate faster. Solids, liquids and gases all expand when heat is added. When heat leaves all substances, the molecules vibrate slower. The atoms can get closer which results in the matter contracting.
