Carbohydrates are an example of a biological macromolecule. The structure of a biological macromolecule affects the function.
inn [45]

Answer:

The functional groups determine the shapes of macromolecules and this in turn determines their functions.

Functional groups affect the bonds that hold a macromolecule together. For example, the ring forms of glucose in starch and cellulose have different configurations. As a result, cellulose and starch serve different purposes.  

Functional groups also affect the polarity of the bonds. Lipids consist of hydrophilic heads (red) and hydrophobic tails (black and white). This characteristic of lipids allows them to form bilayers, which serve as membranes of cells.  

Proteins have complex structures caused by interactions between the functional groups. A change of a single amino acid can make a major change in the function of a protein.

A circle with circumference \blue{8}8start color #6495ed, 8, end color #6495ed has an arc with a 288^\circ288
vivado [14]

Answer:

The arc is 6.4 units long.

Explanation:

For a circle of radius R, the circumference is given by:

C = 2*pi*R

If we have a section of this circle defined by an angle θ (such that this section makes an arc), the length of that arc is:

A = (θ/360°)*2*pi*R

and 2*pi*R is the circumference, then we can write the length of the arc as:

A = (θ/360°)*C

qsIn this case, we know that the circumference is equal to 8 units, and the arc has an angle of 288°

Then the length of that arc is:

A = (288°/360°)*C = (288°/360°)*8 = 6.4

The arc is 6.4 units long.
