1. A scientific law is a statement of fact that describes an action or set of actions. Laws are accepted as fact because they are always observed to be true.

Examples of scientific laws are Newton's laws of motion. These laws describe

the motion of moving objects.

a) Give an example of a scientific law you have studied or heard of. (Think about

what happens when an apple falls from a tree.) (2 points)

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
