Answer:
B: an atom
Explanation:
An atom is the smallest substance that can exist in isolation.
Hence, if a piece of copper is continually divided, eventually the smallest particle you would get in an atom.

Answer:
asexual reproduction through budding in the leaf
Answer:
DNA is a long polymer with a phosphate backbone and deoxyriboses. Adenine, guanine, cytosine, and thymine are the four nitrogenous bases. The backbone of RNA is made up of ribose and phosphate. Adenine, guanine, cytosine, and uracil are four nitrogenous bases.
So DNA is two stranded, RNA is single stranded.

Explanation:
Answer:
C. The trout population decreases as oxygen levels decrease.
Explanation:
We can see that the relationship between the number of trout and time passed is decreasing from the graph on the right because its line is decreasing. From the graph on the left, we can see that oxygen is decreasing as time goes on. Thus, we can interpret that the trout population decreases as oxygen levels also decrease; a proportional relationship.
The other options are incorrect because we can actually see that for...
A; the population of whitefish actually decreases as oxygen levels also decrease.
B; the population of carp actually increases significantly as sewage levels increase.
D; the walleye population actually also decreases overall as sewage levels increase.
