7. How does the Medusa Fish use the Cauliflower Jellyfish?

Medusa is a stage of jelly fish, it reproduces sexually by releasing sperm and eggs into the water and forms a planula.

Explanation:

An adult jellyfish is a medusa. It can reproduce sexually by producing sperm and eggs into the water forming a planula. At the larval stage, the planula hooks on the bottom of a smooth rock and grows into the next stage of jellyfish polyps.

This stage can be for several months or years, the asexual reproduction occurs. These polyps clone themselves and bud into another stage of jellyfish called ephyra.

Jellyfish are carnivores and they eat other animals the small jellyfish eat algae and other tiny plankton called zooplankton.

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
