Answer:
monopolistic competition is when an industry has many firms offering products that are similar but not identical. unlike a monopoly, these firms have little power to set curtail supply or raise prices to increase profit. Monopolies dictate over a specific thing so they are the only thing that is selling.

Answer:
that is the correct answer number 2 try that one
Answer:
1) The angle would be 150 degrees
a) coordinates would be ( 
, 
)
b) Trigonometric ratios:
sin:
cos:
tan: 
csc: 2,
sec: 
cot: 
Explanation:
simplifys to 
which has a reference angle of 
. We can take the coordinates of and make the x value negative to find the correct coordiantes. Then, using those coordinates, plug the into the trigonomic equations.
For example, sin in opposite/hypotenuse. So sin = 1/2 divided by 1. Then you can find the rest of the equations that way.
cos= adjacent/hypotenuse
tan= sin/cos
csc= hypotenuse/opposite
sec= hypotenuse/adjacent
cot= cos/sin
Answer: I and II
Explanation:
The gene flow will be affected because the fragmentation will make it quite cumbersome for birds in the different populations to go to each other and and be able to transfer genetic qualities which is key to genetic diversity.
The founder effect will also be affected. The founder effect is when a smaller group of a larger population are separated from the large population and form a new colony. As they are a smaller group, the genetic diversity will probably be low. With more fragmentation, the founder effect might happen a lot more as the parakeet get separated.
