Levi observed properties of four different waves and recorded observations about each one in his chart. A 2-column table with 4 rows. The first column labeled Wave has entries W, X, Y, Z. The second column labeled Observations has entries travels fastest through metal, travels fastest through air, travels more slowly through water than air, travels more slowly at cool temperatures. Which statement is best supported by the table? Wave W and Y are light waves, Wave Z is a sound waves, and it is impossible to tell what kind of wave Wave X is. Wave W is a light wave, Waves X and Y are sound waves, and it is impossible to tell what kind of wave Wave Z is. Waves W and Z are sound waves, and Waves X and Y are light waves. Wave W is a sound wave, Waves X and Y are light waves, and it is impossible to tell what kind of wave Wave Z is.

Wave W is a sound wave, Waves X and Y are light waves, and it is impossible to tell what kind of wave Wave Z is.

Explanation:

W      travels fastest through metal

X       travels fastest through air,

Y       travels more slowly through water than air    

Z       travels more slowly at cool temperatures

W appears to be sound wave  as sound travels fastest through metal .

X appears to be light wave as light travels fastest in air .

Y also appears to be light wave as  speed of light is reduced when it passes from air to water .

Z  It is impossible to tell anything about the nature of Z wave .

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
