What is similar about the primary structure of each protein? (The proteins are eggs, milk, and meat)

What is different about the secondary, tertiary, and quaternary structure of each protein?(The proteins are eggs, milk, and meat)

For the proteins you researched, how does the structure help the protein perform its function?(The proteins are eggs, milk, and meat)

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

the components of a vector are the parts of the vectors that are to each other.

b perpendicular
