I need help answering there question, here are the questions and responses.
Question 12(Multiple Choice Worth 3 points)
(03.02 HC)
The figure below shows four components of an aquaculture system. The components are interconnected to form one complete system. Each component has a sealed top and is connected to the other components as shown by the arrows. The components are not temperature controlled, and heat can enter or leave through the walls. Explain whether this represents a closed or an isolated system and one benefit of using this type of system.
an aquaculture system that contains biological filtration with an arrow pointing from either side of the biological filtration to the next process which is waste to the right and a closed fish container to the left. From the fish container the next step shows water passing through the fish container into the mechanical filtration and then eventually back to waste or through to biological filtration at the top of the process.

This represents a closed system, and one benefit is that all waste is recycled in the system.
This represents a closed system, and one benefit is that the risk of passing disease between other species is lower than in an open system.
This represents an isolated system, and one benefit is that it does not release organic waste to cause pollution.
This represents an isolated system, and one benefit is that waste does not accumulate in the system.

Fossil evidence has been used to understand the movement of continental plates. A particular species of animal originated in Asia during the Cretaceous period. It was able to spread across touching landmasses, but not across oceans. Predict which of the following could be true of its fossils, using the figure below.
Maps showing the Permian Period (225 million years ago) when the continent was known as Pangaea, Triassic Period (200 million years ago) shows the splitting of Pangaea into two continents; Laurasia and Gondwana Land, The Jurassic Period (150 million years ago) shows the separation of the continents increasing and into smaller continents, The Cretaceous period (65 million years ago) shows a further separation of the continents with more water in-between the continents. The last map image shows present day continents North America, South America, Africa, Asia, Australia and Antarctica.

The fossils could be found in both North and South America.
The fossils could be found in North America and Asia.
The fossils could be found in North America and Australia.
The fossils could be found on all continents.
Question 14(Multiple Choice Worth 3 points)
(01.04 LC)
You are on a field trip and are recording the amount of mass in a volume of water. What are you measuring?
The concentration of bacteria in seawater
The concentration of dissolved oxygen in seawater
The concentration of salt in seawater
The density of seawater
Question 15(Multiple Choice Worth 3 points)
(03.01 MC)
Climate change can have a large impact on coral reefs. How does climate change impact coral?
Climate change decreases the pH of seawater, which makes it harder for coral to grow.
Climate change lowers the temperature of seawater, which interferes with coral's symbiotic relationship with algae.
Climate change keeps pH levels of seawater stable, which allows coral to grow rapidly.
Climate change raises the temperature of seawater, which interferes with coral's symbiotic relationship with algae.
Question 16(Multiple Choice Worth 3 points)
(03.03 MC)
You call to a friend from a boat floating in the ocean. Which best describes the changes in the speed of the sound waves as they move from you to below the surface of the ocean?
The speed of sound is faster in the water than in the air.
The speed of sound is faster in the air than in the water.
The speed of sound does not change as it moves through the air or water.
The speed depends on how loud you yell.
Question 17(Multiple Choice Worth 3 points)
(02.01 LC)
What is the role of convection in plate tectonics?
Convection causes the mantle to move, which moves the plates.
Convection in the earth's core causes the plates to move.
Convection in the earth's crust causes the seafloor to spread.
Convection in the oceans pulls the seafloor.
Question 18(Multiple Choice Worth 3 points)
(03.06 MC)
How does the diversity of life in the sublittoral zone compare to that of the upper intertidal zone?
There is more biodiversity than in the upper intertidal zone because there is less temperature variation in this region.
There is more diversity than in the upper intertidal zone because there is a higher level of salinity in this region.
There is less diversity than in the upper intertidal zone because there is a lower level of oxygen available.
There is less diversity than in the upper intertidal zone because there is greater exposure to predators here.
Question 19(Multiple Choice Worth 3 points)
(01.01 MC)
In order to understand the impact of climate change, a scientist collected measurements of average yearly sea surface temperatures from 1880 to 2012. His data is graphed below. What scientific question could be most accurately investigated based on the data collected by this scientist?
a graph depicting yearly sea surface temperature from 1880-2012. The X axis represents the years from 1880 to 2010 in increments of ten years. The Y axis represents the difference from average temperature in degrees Fahrenheit ranging from -1.6 to 0.6. 1880 shows a temperature difference of -0.8, 1890 shows a temperature difference of -1.1, 1900 shows a temperature difference of -1.05, 1910 shows a temperature difference of -1.5, 1920 shows a temperature difference of -1.15, 1930 shows a temperature difference of -0.9, 1940 shows a temperature difference of -0.55, 1950 shows a temperature difference of -0.8, 1960 shows a difference of -0.5, 1970 shows a difference of -0.7, 1980 shows a temperature difference of -0.3, 1990 shows a temperature difference of -0.2, 2000 shows a temperature difference of -0.19 and 2010 shows a temperature difference of 0.1.

Question 20(Multiple Choice Worth 3 points)
(03.03 HC)
A blue tang is a tropical fish that is blue in color. What property of light waves causes the blue tang to appear blue?
As light moves through the water and strikes the tang, only blue light is absorbed.
As light reflects off the tang, all colors except blue are diffracted.
As light strikes the tang, all colors of light except blue are absorbed.
All the colors are equally refracted off the tang, but blue travels the furthest.
