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.

Answer:
Option 1, a charged end and a noncharged end
Explanation:
Complete question
If a small droplet of ordinary fat is suspended in water, the fat molecules form a "ball of spaghetti" with no particular orientation. But if a droplet of phospholipid molecules is put in water, all the molecules point outward, toward the water. Phospholipids are forced into this orientation because phospholipids have _____
- a charged end and a noncharged end
- three fatty acid molecules, all pointing in different directions
- two fatty acid molecules pointing in different directions
- both a saturated fatty acid and an unsaturated fatty acid
- two charged ends
Solution
The structure of phospholipids consists of the following groups and molecules –
a) A glycerol molecule
b) Fatty acids (2 in numbers) – It is hydrophobic as it is uncharged and non polar in nature
c) Phosphate group (with alcohol) – It is hydrophilic as it is negatively charged and polar in nature.
When the phospholipids are placed in water, the molecule rearranges itself in a way that the hydrophobic head face inside and the hydrophilic head face outside thereby forming micelles.
Hence, option 1 is correct
Sorry i cant see that question
B. is the correct answer I think
