The answer is not D, because water creates turgidity.
The answer is not C, because water is important in many biological reactions.
The answer is either A, or B. Knowing that water composes almost 75% of the body, you can assume that It is a common substance, for A, or you could know that is allows reactions to occur more easily, acting as a sort of catalyst, for answer B. 
A or B. Your call for the final answer.

wolverine [178]

1. Silicon is in the same group and also has 4 valence electrons.
2. covalent
3. 1
4. Wood
6. 1s22s22p2
7. Covalent

Those questions were somewhat simple. Questions #5 and #8 I'm not certain of and if you have any kind of textbook or course material, it'd be beneficial to look at it. I hope you were able to figure out the answer to Question #4 was "Wood", otherwise your teacher must be slacking :P. I'll try to figure out the answers to #5 and #8 and let you know what I figured out.

1. What is the maximum amount of NaCl that can dissolve in
Sergio [31]

Answer:

70g

Explanation:

Rate = 35g of NaCl can dissolve in 100g of H2O

Use proportions for 200g of H2O:

\frac{35}{100} = \frac{x}{200}

Since 200 is double of 100, x needs to be double of 35.

\frac{35}{100} = \frac{70}{200}

Therefore the maximum amount of NaCl that can dissolve in 200g of water is 70g.
