Translations and Reflections

Why does the lower part of the child appear so much different in size from the upper part?

• The light rays that travel through water and then into air are refracted.

• The light rays that travel through water and then into air are enlarged.

• The light rays that travel through air and then into water are reflected.

• The light rays that travel through air and then into water are reduced.

What is the angle of incidence?

• The angle at which light bends in water.

• The angle at which light hits a surface.

• The angle at which light is absorbed by an object.

• The angle at which light bounces off a surface.

What does tRNA do during translation?

• it brings a specific segment of DNA to the ribosome for transcription

• it brings any amino acid to the ribosome

• it brings a specific amino acid (decided by the DNA) to the ribosome for translation

• it brings a specific amino acid (decided by the codon) to the ribosome for translation

Objects that reflect well are

• Matte surfaces

• Smooth, shiny surfaces

• Dark coloured surfaces

• Medium coloured surfaces

Lateral inversion is

• When a light ray hits an object as a curved wave

• The term used to describe light rays reflecting off dark, matte surfaces

• The same as 'angle of incidence'

• When something is reflected in a plane mirror where left becomes right and right becomes left

What is the primary function of mRNA during translation?

• It carries the genetic code from DNA to the ribosome

• It brings amino acids to the ribosome

• It forms the structure of the ribosome

• It catalyzes the formation of peptide bonds

Which of the following best describes a reflection in physics?

• The bending of light as it passes through a medium

• The bouncing back of light from a surface

• The spreading of light waves

• The absorption of light by a surface
