False in order for an ecosystem to survive there has to be some sort of competition. for example, if there were no sharks to eat little fish the little fish would over populate and then the little fish would run out of food which then means that whatever the little fish ate is now extinct and so on hinting the food chain's name. If it wasn't for competition nothing would survive
Answer:
There are four students working on a project in math class. Miguel has completed 1/8 of the project, Gina has completed 13% of the project, Jatziry has completed 0.10 of the project, and Keva has completed 1/9 of the project. Make a list of the students in order from least to greatest by the amount of the project they have completed.

Answer:
40x, 100x, and 400x
Explanation:
The ocular lens (closest to your eye) usually has a 10x power.
The objective lenses (closest to the object) usually have powers of 4x, 10x, and 40x.
Combined, they give magnifications of 40x, 100x, and 400x.
Answer: option B) 0.25
Explanation:
Total population of four o’clock flowers = 8
Number of red flowers with RR phenotype = 5
Number of pink flowers with Rr phenotype = 2
Number of white flower with rr phenotype = 1
To obtain the phenotype frequency of plants with pink flowers:
put the number or Rr phenotype OVER the total population of four o'clock plants
i.e 2/8
= 0.25
Therefore, 0.25 is the answer
