Answer: The choice of a submarine to either sink or float depends on the captain of that submarine. For a submarine to sink the captain just have to allow water to fill the water tank (lock), making the submarine more dense than the water it has displaced. For it to float, it just have to empty the water tank and allow air to fill it.
When a boat in a canal lock sank, the water level will rise, because the volume of the boat has displaced more water, and this displaced water will cause the water level to rise. The space occupied by an object in a water, is equal to the volume of water been displaced.
A photo's color intensity can be modified by changing the brightness and contrast. This type of situations are best known by professional cameramen.

Explanation:
Parellel play occurs when children play in the same area as others, but don't interact directly. It differs from associative play because parallel is imitative (i.e. both kids are doing the same activity), and associative <u>involves different types of activities, and a considerable degree of interaction</u>.
Cooperative play is when children are interested in each other's activities, play together and present an organised structure. They usually assign roles (in the example, one of them swings the rope and the other jumps).
Scholars use the term gender to refer to the psychologist, social, and cultural differences between women and men.
