Answer:
In a fair test two or more things are compared. In order for a test to be fair or scientifically sound, children are required to ensure only one thing (this is called a variable) is changed.
For example, if testing which material is the most waterproof by pouring liquid onto a selection of different materials, in a fair test only the type of material (the component you are testing) should be changed. Therefore all other elements (the type of liquid used, the amount of liquid used, the distance the liquid is poured from, the speed at which it is poured and the size of the material) must remain the same each time the test is carried out. It would be unfair or an unscientific test if, for example, 1000ml of water were poured onto a piece of foil and 2ml of milk poured onto a piece of foam – you would not be able to fairly compare the materials.
hope this will help you!!!.....

hi :)
The relationship described is predator-prey.
The orca is hunting and eating other organisms, which is known as a predator-prey relationship.
In case you need help with any more of these-
Mutualism is when both animals get something out of the relationship, for example, some kinds of shrimp get the food out of fishes teeth. The fish gets clean teeth, and the shrimp gets a meal.
Parasitism is fairly self-explanatory. This is when a parasite lives and gains from a host, while the host is harmed and could get diseases from the parasite.
Commensalism is when one animal benefits and the other isnt harmed nor benefited. An example of this is the remora fish which clings to the bottom of other fish when it gets tired.
Lastly, Competition. This is when two organisms compete for something they need to survive. For example, two lions could compete for a food source, such as a zebra. Usually, the strongest and fastest organism survives, or wins.
Alrighty, I hope this helped!!
Good luck with the rest of your assignment!!
