Numerous compounds present in nature have isometries. An example of this are amino acids, which enter into the constitution of proteins. Analyzing the two amino acids separately, is it possible to say that they have an isometry type?

A) Function plane
B) Position plane
C) Geometric
D) Optics
E) Chain plane

How did you reach that conclusion?

Make sure you are keeping your points right by posting the correct answer!

C) Geometric

Explanation:

Imagine two ants sitting on a triangle while you move it from one location to another. The location of the ants will change relative to the plane (because they are on the triangle and the triangle has moved). But the location of the ants relative to each other has not. Whenever you transform a geometric figure so that the relative distance between any two points has not changed, that transformation is called an isometry.

i can ! i just need to know what the paragraph is! : p

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
