Answer:

2 Worms were added to the population that week

Explanation:

Your equation is 9-10-5+8 =2

You get this because if 9 worms are born they are  coming into the population then you would do -5 because they died and were taken away from the population then move to -10 and this was because they emigrated out of the population and into another then finally you have the +8 because they immigrated into the population

Why do we exist? Very hard question...
STatiana [176]

Answer:

We exist to see if we can past the test God gives us through our lifetime here on Earth. We exist because God put us here on Earth, with the first man being made of clay, and the first woman being made of the clay from the ribcage of the man.

Explanation:

We face many tests in our lives, whether we notice them or not. We are then given praises for passing tests and gain sins for failing tests and doing wrong.

Tests can come in many ways, such as picking up something that someone dropped, being polite, controlling anger, staying focussed, and more.
