Which statements describe s waves? check all that apply.

they move side to side.
they arrive after p waves.
they travel through solids.
they travel through liquids.
they occur at earth's surface

Seismic waves...

They move side to side. ✔

They arrive after P waves.✔

They travel through solids.✔

They travel through liquids.

They occur at Earth's surface✔

The correct answers are "They move side to side", "They arrive after P waves" and "They travel through solids".

Explanation:

S-waves are one of the two types of seismic waves, named after "secondary waves" for being the second waves that arrive to a seismic center after the P-waves (primary waves). S-waves move side to side, therefore they are considered transverse waves. S-waves move through the body of solids, unlike other waves that move in the surface of the objects.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!

b tumor cells have a cell wall instead of a membrane

explanation:

tumor cells different from normal cells because tumor cells have a cell wall instead of a membrane.
