According to Piaget, during the formal operational stage, adolescents employ propositional thought which is reasoning that uses abstract logic in the absence of concrete examples
The concrete operational stage: age 7 to 11
As children continue into elementary school, they become able to represent ideas and events more flexibly and logically. In the concrete operational stage, for example, a child may unconsciously follow the rule: “If nothing is added or taken away, then the amount of something stays the same.” This simple principle helps children to understand certain arithmetic tasks, such as in adding or subtracting zero from a number, as well as to do certain classroom science experiments, such as ones involving judgments of the amounts of liquids when mixed. Piaget called this period the concrete operational stage
What is formal operational stage Piaget?
The formal operational stage is the fourth and final stage of Jean Piaget's theory of cognitive development. It begins at approximately age 12 and lasts into adulthood. At this point in development, thinking becomes much more sophisticated and advanced

The two type of changes are:
1. Independence
When a certain nation declared its independence, their territory is no longer belong to the country that colonize it. Which means that the national boundary undergone a change in ownership. Before the independence, it belonged to the country that colonize the nation. After the independence it belong to the nation itself.
Example: South American countries declared independence from Spanish Empire
2. State Annexes
During annexation, a certain territory is acquired by another country (could either be done through forces or consensual method). When annexation occurs, the national boundaries of the country that being annexed now belong to the nation that annexed it.
Example: When West Papua was acquired by Indonesia.
I would say C most people go along with what the rest of the people do, if observers didn’t do anything it’s more likely because no one else was.

Deterioration of physical appearance, personal grooming habits.
Runny nose or sniffling.
Sudden weight loss or weight gain.
Explanation:
Based on the organization of plants and animals at a cellular level, the following is true:
- 1) Membrane protein complexes that strengthen the adhesion between adjacent cells, like rivets, to protect against pulling forces. - Desmosomes - Animal.
- 2) Small channels that form across the plasma membranes of adjacent cells; especially important in intercellular communication. - Gap junctions. - Animals.
- 3) Membrane proteins that create watertight seal between cells. - Tight junctions - Animals.
- 4) Small channels between cells that are otherwise surrounded by walls; enable movement of water and solutes between cells. - Plasmodesmata - Plant.
- 5) A polysaccharide that is used to synthesize cell walls, which protect cells and help maintain their shape. - Cellulose - Plant.
- 6) Long fibers of protein found in the extracellular matrix that provide structural support for cells. - Collagen - Animal.
<h3>Features of plant and animal cells</h3>
Animals are known to desmosomes, gap junctions, tight junctions, and collagen to help cells fulfil their duties and keep the body functioning.
Plants have plasmodesmata, and cellulose which ad the plant by helping cells perform their functions.
