Answer: If lava hit water it forms rock that helps make islands and moutains
Explanation:
Group 2 contains soft, silver metals that are less metallic in character than group 1 elements. There is a fairly strong conductivity trend within each row, left to right, and a weaker trend top to bottom. The elements in group 2 are moderately good conductors, while the elements on the right are very poor conductors. <span>As you move vertically between rows, conductivity decreases overall, but slowly.
Group 2 have a generally low electronegativity. Electronegativity decreases moving left and down across the table.</span>
Whiskers and beaks
are two examples of _____. electroreceptors mechanoreceptors olfactory
receptors photoreceptors
Whiskers and beaks
are two examples of olfactory receptors. An olfactory receptor is a smell
receptor that contains a protein capable of binding odor molecules that plays
the central role of smell.
Answer:
B) diffraction
Explanation:
A smooth pane of glass does not diffract light. A light passing through a smooth pane of glass may be absorbed, reflected or transmitted.
Diffraction only occurs with special types of glasses embedded with a diffraction grating and are called super prisms. Diffraction glasses use a a gradient lens which is able to separate light into all the colors of the rainbow.
Recall that diffraction is the separation of white light into its component wavelengths.
Answer:
periods and groups
Explanation:
periods are the columns on the periodic table
groups are the rows on the periodic table
