In a marine ecosystem, a large already existing population of purple-colored sea urchins increases as the starfish eats other colors is a type of directional selection.

<h3>What is directional selection?</h3>

Directional selection is the type of natural selection in which an extreme phenotype is favored and has its frequency increased in the population. It is the type of selection that causes changes more quickly than the others, being the type most used in artificial selections.

With this information, we can conclude that in a marine ecosystem, a large already existing population of purple-colored sea urchins increases as the starfish eats other colors is a type of directional selection.

A jar contains 26 fluid ouncesbof spaghetti sauce. How many cups of spaghetti sauce do 4 jars contain
JulijaS [17]

____________________________________________________

Answer:

Your answer would be 13 cups of spaghetti sauce.

____________________________________________________

Explanation:

Lets break down this question to make the answer easier:

8 ounces = 1 cup

We are going to use the above to help us solve this question.

In your question, you have 26 ounces, and you would have four cups. You would need to calculate how many ounces are in the 4 cups

To do this, you would multiply 26 by 4:

26 × 4 = 104

The four cups have a total of 104 for ounces. But, you are not done solving yet. You need to found how many cups there are. We would be going to use the 8 ounces, since we know that is the amount of one cup, and use that to divide 104, since we need to distribute the amount of ounces to the cups.

You would divide 104 by 8

104 ÷ 8 = 13

There would be 13 cups of spaghetti sauce in 4 jars of spaghetti sauce that has 26 ounches in it.

Your FINAL answer would be 13.
