grandymaker [24]

Answer:

The correct answer is c) are plant cells.

Explanation:

The cells cannot be animal cells, because they have not wall (this kind of cells has only plasma membrane). In addition, eukaryotic cells have membrane-bound organelles (which are surrounded by a phospholipids membrane, such as endoplasmatic reticulum, Golgi apparatus, lysosomes, etc.), whereas prokaryotic cells lack them. Since plant cells are eukaryotic and bacterial cells are prokaryotic, the cells you are looking are plant cells.

Answer:

1. Cinder cones

2. All of these

Explanation:

1. Cinder cones develop from explosive eruptions of mafic (heavy, dark ferromagnesian) and intermediate lavas and are often found along the flanks of shield volcanoes. The outside of the cone is often inclined at about 30°, the angle of repose (the slope at which the loose cinder can stand in equilibrium).

2. Volcanic Explosivity Index (VEI) is a numeric scale that measures the relative explosivity of historic eruptions. Volume of products, eruption cloud height, and qualitative observations (using terms ranging from "gentle" to "mega-colossal") are used to determine the explosivity value. The Volcanic Explosivity Index (VEI) was derived to catalogue the explosive magnitude of historical eruptions, based on the order of magnitude of erupted mass, and gives a general indication as to the height the eruptive column reached.

Hope this helps!
