The answer is; C
In folding, when segments of Earth's crust are bent and doubled over, the sediments in between are form folds, since they are forced into a smaller space. This also occurs in converging plates boundaries.
Block Mountains occur when stress due to compression in the crust causes the hanging wall between a fault to move up relative to the footwall.
<u>Answer:</u> The Henry's law constant for oxygen gas in water is 
<u>Explanation:</u>
To calculate the molar solubility, we use the equation given by Henry's law, which is:

where,
= Henry's constant = ?
= solubility of oxygen gas = 
= partial pressure of oxygen gas = 2.1 atm
Putting values in above equation, we get:

Hence, the Henry's law constant for oxygen gas in water is 
C. Primary consumers
Explanation:
Producers are like grass, herbivore is like a cricket and primary consumers is like a bird
Answer:
The water would be neutral, (usually 7). The salt water would be the same (7) and the vinegar would be very acidic. (probably 2).
Explanation:
Density is not a chemical property. It is a physical property.Electromotive force, Flammability and pH are chemical properties.
