Jet streams are fast moving air currents much like how a river is a fast moving water current so the answer is jet streams.
Heterotrophic- has a nucleus and many different organelles
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.
When analyzing data scientists look for patterns, that help them form predictions.
Patterns are rules that variations/characteristics follow, either in data or anything else patterns might be used for.
Example:
The fact that worms are found always 10 meters forom eachother (not true, it's an example) is a pattern, that will help you predict the location of the next worm.

Answer: Hind wings have tail extensions.
Explanation:
The dichotomous key is a tool which is used by the scientists to identify the unknown living organisms by comparing the observable characteristics of unknown with known living organisms. It stresses to identify the organisms or species by their scientific names and every species has a particular scientific name. Hind wings of butterfly is the observable characteristic which can be compared with that of other known butterfly species that also have a tail extension. This physical characteristic will help in identification of butterfly.
