Which statement about glaciers is true? a) glaciers can only be found high up in mountains b) glaciers have snow all year round, except during july, c) there are two types of glaciers: alpine and continental d) glaciers can only be found near earth's north and south poles.

Option C

Explanation:

Glaciers can be found at the place that has very low temperature. Low temperature can be defined as freezing temperature as glaciers can be defined as layers of ice one on another.

Glaciers are can be found high on mountains and on land regions. In the land regions glacier are found near the north and south pole. Glaciers are found almost everywhere where there is a freezing temperature.

There are two types of glaciers known as alpine and continental. The alpine glaciers are found in the mountains and it flows down through valley.

Continental glaciers are known as ice sheets and are more larger than alpine glaciers.

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!
