Answer:
The amount of matter within the system remains the same.
The cycle has a well-defined starting and stopping point.
Explanation:
A closed system can be defined as a system in which there is the only exchange of energy with the surrounding, while no exchange of matter takes place.
In a closed system, the cycle has a well-defined starting and stopping point.
Therefore, the two generalizations which can be made for cycles of matter in a closed system are option 3 and 5)
Answer:
Explanation:
This is called a series, to solve it you need to give the first hop which is going to move you 1/3 of the way, the you hop another time, this will move you 1/3 of the 2/3 missing, this means you have moved now:
and you are missing 4/9 of the way.
Next hope will move you 1/3 of the 4/9 missing, which is 
, adding this to the path you have already moved is:
and you are missing 8/27 of the way.
The fourth hop is the same, one third of the missing path: 
, and adding this to the traveled path:
and you are missing 16/81 of the way.
The last and fifth hop is again one third of the missing path: 
, and adding this to the already moved way:
And you end here.

This suggestion best illustrates D. an evolutionary perspective.
Explanation:
The evolutionary perspective seeks explanations for behaviors taking into consideration our species need to adapt and reproduce. From this perspective, our behaviors result from problems our ancestors encountered over 10,000 years ago. Since the purpose of the species is to perpetuate itself, many of our behaviors could be explained by the instinct of reproduction. We look for good mates in order to procreate. That perspective would, therefore, explain men who marry younger women as a result of our reproductive needs - young means fertile, at least instinctively.
