Svet_ta [14]
Smaller cube (1 cm X 1 cm X 1 cm) 

<span>The surface area of one side = 1 cm X 1 cm = 1 <span>cm2</span></span>

 

<span>There are 6 sides, total SA = 6 X 1 <span>cm2</span> = 6 <span>cm2</span></span>

 

<span>Volume = 1 cm X 1 cm X 1 cm = 1 cubic cm (1 <span>cm3</span>)</span>

<span>Surface to Volume Ratio = 6 <span>cm2</span>/1 <span>cm3</span> = 6 <span>cm2/cm3</span></span>


Larger cube (6 cm X 6 cm X 6 cm) 

<span>The surface area of one side = 6 cm X 6 cm = 36 <span>cm2</span></span>

 

<span>There are 6 sides, the total SA = 6 X 36 <span>cm2</span> = 216 <span>cm2</span></span>

 

<span>Volume = 6 cm X 6 cm X 6 cm = 216 <span>cm3</span></span>

Answer:

All given options are correct.

Explanation:

Biomolecules may be defined as the organic molecules that are present in the living organism. Four important biomolecules are proteins, carbohydrates, fats and nucleic acids.

The biomolecules are known as macromolecules because they are made of large units of molecule. The mRNA that translates to form a enzymes is macromolecule because RNA is made of large units of nucleotides. Lipid that found in cell membrane are macromolecules because they are made of more than 1000 atoms. Protein that are involved in DNA replication are macromolecules as they have large units of amino acids.

Thus, all the given option are correct.
