El oxígeno que inhala del aire pasa a través de los pulmones a la sangre a través de los muchos capilares en los pulmones. La sangre rica en oxígeno se mueve a través de sus venas pulmonares hacia el lado izquierdo de su corazón y de la aorta hacia el resto de su cuerpo.

which of the macromolecules tested in this exercise (proteins, lipids, nucleic acids) were formed by dehydration reactions? expl
aalyn [17]

Large polymers are created during dehydration synthesis, which are typically referred to as biological macromolecules. These compounds include proteins, lipids, carbohydrates, and nucleic acids.

As a result, the dehydration reaction is responsible for the formation of protein, lipid, and nucleic acids.

1. Protein structure

  • Amino acid polymers form proteins. There are four different types of proteins, based on structure.
  • The amino acid sequence of a protein is represented by its primary structure, which is a linear chain.
  • The backbone (main chain) atoms of a polypeptide are arranged locally in space to form the protein's secondary structure.
  • A polypeptide chain's whole three-dimensional structure is referred to as a protein's tertiary structure.
  • The protein's quaternary structure, which is a three-dimensional arrangement of the subunits of a multi-subunit protein.

2. Lipid structure is a crucial element of the cell membrane. The structure is mostly composed of a glycerol backbone, two hydrophobic fatty acid tails, and a hydrophilic phosphate group.

3. Nucleic acids' structure: Nucleotide polymers make up nucleic acids. Each nucleotide is made up of an aromatic base with a N-atom connected to a pentose sugar with five carbons, which is then joined to a phosphate group.

Answer:

Either (1.) Fossils or (2) Radiometric dating.

Explanation:

Fossils are an obvious answer to this, but radiometric dating is the method most scientists use to find the age of rocks. Radioactive isotopes break down predictably, so the farther along this process is, the older the rock is.
