Which statement best describes most tundra animals? A. slender and short, so they can move quickly
B. hardly any fur or feathers because they are warm-blooded
C. stocky bodies covered with thick fur or feathers
D. most of their time is spent underground, so they are insulated

C. stocky bodies covered with thick fur or feathers

Explanation:

Animals in the tundra generally have stocky bodies covered with thick fur or feathers.

A tundra is a very cold biome. In fact, it is the coldest of all the biomes found on the earth. This region is found in the Arctic and other parts of the world. It is treeless, very cold and has little to no precipitation all year round.

explanation:

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%
