Answer:

<em>B. All living organisms are composed of one or more cells, which came from pre-existing cells. </em>

Explanation:

Scientific theory is given as an answer to a natural happening in the earth but scientific laws are detailed idea of how nature will act under certain conditions.

Theories are given after an experiment has been performed under controlled conditions. Scientific theory cannot be changed to scientific laws and scientific laws cannot be changed to scientific theory.

Scientific theories are broader in scope, and give overall clarifications of how nature functions and why it shows certain attributes. Similarly, all cells comes from pre-existing cells is an example of cell theory.

The number of ducks in a pond is equal to the square root of the number of fish, and the number of turtles is equal to the cube
brilliants [131]

Answer:

There are 64 fish, 8 ducks and 4 turtles.

Explanation:

From the question, there can be from 2 to 99 fish in the pond. However, there cannot be fractions in the number of fish, ducks or turtles. Hence, the number of fish must have both of a perfect square and perfect cube. The perfect squares from 2 to 99 are 4, 9, 16, 25, 36, 49, 64 and 81. The perfect cubes from 2 to 99 are 8, 27 and 64. Since only 64 fits both criteria, the number of fish is 64. The number of ducks is the square root of number of fish, which is the square root of 64. The square root of 64 can be either positive 8 or negative 8. However, there cannot be negative numbers, so there are 8 ducks in total. The number of turtles is the cube root of the number of fish, which is the cube root of 64 and it is 4.
