Answer: Convergent evolution occurs when two species living in different areas evolve similarities through natural selection acting on those characteristics.
Explanation:
Phosphorus is the element found in nucleic acids but not in proteins.
<h2>Further Explanation
</h2><h3>Proteins </h3>
- Proteins are one of the major biomolecules that exists in nature.
- They are made of amino acids which are the building blocks. Amino acids contain four different elements which include;
- Hydrogen
- Oxygen
- Nitrogen
- Carbon
- Some amino acid contains sulfur element.
<h3>Nucleic acids</h3>
- Nucleic acids are one of the four major bio-molecules in nature. Nuclei acids is divided into two; RNA and DNA.
- The building blocks of nucleic acids are Nucleotide bases which are made by a nitrogenous base, a sugar and a phosphate group.
<h3>DNA </h3>
- DNA is a nuclei acid that is responsible for carrying genetic information in living organisms.
- It is through DNA that genetic information is passed from one organism to another through the process of DNA replication.
- Additionally, it carries the information that is used to make proteins which performs various functions in living cells.
- Each Nucleotide in DNA contains a nitrogenous base, a deoxyribose sugar, and a phosphate group.
- DNA molecules are made up of nitrogenous bases; Adenine, Guanine, Cytosine and Thymine.
<h3>RNA
</h3>
- Ribonucleic acid (RNA) is a type of nucleic acid, a molecule that plays a major role in the flow of information from the DNA to the proteins. For a gene to be expressed information has to be passed through the RNA.
- Each nucleotide in RNA contains a nitrogenous base, a ribose sugar, and a phosphate group.
- Nitrogenous bases in RNA includes; Adenine, Guanine, Cytosine and uracil. Thymine in DNA is replaced with Uracil.

Higher, lower is correct I believe.
All living cells and many of the tiny organelles internal to cells are bounded by thin membranes. These membranes are composed primarily of phospholipids and proteins and are typically described as phospholipid bi-layers.
