14Ways that marine [blank_start]ecosystems[blank_end] are affected by chemical spills:
- Habitats of [blank_start]organisms[blank_end] are destroyed, so they have no [blank_start]shelter[blank_end] and die.
- [blank_start]Oil[blank_end] or similar pollutants coats the animal, so it can no longer catch [blank_start]pray[blank_end]. As a result, it will [blank_start]starve[blank_end] and die.
- The food source of predators is [blank_start]reduced[blank_end], which [blank_start]affects[blank_end] all the organisms in the web.- Afishes
- Banimals
- Cecosystem
- Dpeople
- Eorganisms
- Fneturalists

15When comparing filtering, evaporating, and decanting, which seperation methods could be described by each statement?
a. Seperates an insoluble solid from a liquid. [blank_start]Filtering & Decanting[blank_end]
b. Seperates a soluble solid from a liquid. [blank_start]Evaporating[blank_end]
c. Uses different densities to seperate. [blank_start]Decanting[blank_end]
d. Uses differing boiling points to seperate. [blank_start]Evaporating[blank_end]
e. Uses different particle sizes to seperate. [blank_start]Filtering[blank_end]

16Neutralisation is when an acid reacts with just enough [blank_start]base[blank_end] to form a [blank_start]solution[blank_end] with a [blank_start]pH value[blank_end] of exactly 7.
- Abase
- Bsolution
- CpH value
17A mixture of sand and salt needs to be separated into individual piles. Put these steps in the appropriate order:
1. [blank_start]Add water[blank_end]
2. [blank_start]Decant the mixture[blank_end]
3. [blank_start]Filter the mixture[blank_end]
4. [blank_start]Heat the mixture over a Bunsen Burner[blank_end]- AAdd water
- BDecant the mixture
- CFilter the mixture
- DHeat the mixture over a Bunsen Burner
18Biodiversity is the [blank_start]measure[blank_end] of the [blank_start]varirety[blank_end] of all different [blank_start]species[blank_end].
- Ameasure
- Bvarirety
- Cspecies
19Label the parts of the flower.
Words: style, stigma, ovary, anther, ovule, filament, sepal, petal.
[Note: the ovule is the dot ON the ovule. The ovary is the dot in the ovary-area, but not on the ovules. To clear any confusion with the labels.]
