can you help me with my test plzz. here are the questions and what are the answers. thank you.
A marine scientist measures the energy found in a system consisting of a shark and fish. After the shark consumes the fish, the marine scientist concluded that chemical energy from the fish was transformed to kinetic energy in the shark. Does this result validate or invalidate the Law of Conservation of Energy?
Invalidate, because energy should not leave a closed system
Invalidate, because the type of energy should stay the same
Validate, because energy can change forms
Validate, because energy can be destroyed
Question 4(Multiple Choice Worth 3 points)
(03.02 MC)
A marine biologist measured the amount of heat radiated from an aquarium over the course of an experiment. He concludes that the aquarium is an open system. Explain why this conclusion is invalid.
An open system does not exchange energy with its surroundings, and the scientist only measured the exchange of heat.
An open system does not exchange matter with its surroundings, and the scientist did not measure the movement of matter.
An open system exchanges both energy and matter with its surroundings, and the scientist did not measure the movement of matter.
An open system exchanges matter but not energy with its surroundings, and the scientist did not measure the movement of matter.
Question 5(Multiple Choice Worth 3 points)
(03.03 LC)
A person flying in a plane over Easter Island notices that the water around the island appears bluer than the surrounding water. What property of light waves causes the water to be a different color to the observer?
Absorption
Diffraction
Construction
Destruction
Question 6(Multiple Choice Worth 3 points)
(03.02 LC)
A system in which matter and energy move freely is called
a non-contact system
an isolated system
a physical system
an open system
Question 7(Multiple Choice Worth 3 points)
(03.02 MC)
When ocean waves hit the beach, kinetic energy is stopped by the sand and rocks on the beach. The energy is then lost from the ocean. How does this example show the Law of Conservation of Energy?
The energy is transformed to vibrational energy in the sand, rocks, and air.
The Law of Conservation of Energy applies to solids, not liquids.
The beach is an isolated system, so energy is allowed to exit the system.
The energy from the water is destroyed.
Question 8(Multiple Choice Worth 3 points)
(03.06 MC)
Most aquatic organisms are adapted to a narrow range of salinity. Why must aquatic organisms living in coastal areas be adapted to survive in both low and high salinity?
During high tide, organisms are exposed to air, lowering salinity.
During low tide, the ocean water becomes concentrated, increasing salinity.
Ocean currents bring in deep-ocean water with high salinity concentrations.
Temperature fluctuations can cause changes in the salinity levels of the water.
Question 9(Multiple Choice Worth 3 points)
(03.05 LC)
Using the graph below, indicate what type of tide occurs in the Gulf of Mexico.
Graph shows the tidal pattern in the Gulf of Mexico. High tide occurred at 12 hours and 25 min and was a height of 1 meter. Low tide occurred at 24 hours and 50 minutes and was a height of -1 meter.

Mixed
Semi-diurnal
Spring
Question 10(Multiple Choice Worth 3 points)
(03.01 MC)
The humpback whale migrates across areas of the Pacific Ocean, from Hawaii and California in the winter to Alaska in the summer. Why would humpback whales migrate north in the summer?
They follow jet streams to deeper waters.
There is more food in northern regions during the summer.
They prefer warmer waters year-round.
They must return to the same region to breed, whether in the south or in the north.
Question 11(Multiple Choice Worth 3 points)
(03.03 LC)
The distance from a wave's equilibrium point to its crest is known as what?
Amplitude
Trough length
Wavelength
Wave height
Question 12(Multiple Choice Worth 3 points)
(03.03 MC)
Most filter-feeding whales have calls between 15 to 25 hertz, but one type of filter-feeding whale has a much higher frequency, at 52 hertz. What likely differs between the two whale calls?
The place of equilibrium
The height of the waves
The time it takes for successive crests to pass through a point
The amplitude
Question 13(Multiple Choice Worth 3 points)
(03.03 MC)
A marine biologist is studying dolphin calls and notices that sometimes the calls sound louder based on the background noise in the water. She concludes that the sound waves are adding together. What type of wave interference does this describe?
Constructive
Dismissive
Destructive
Refractive
Question 14(Multiple Choice Worth 3 points)
(03.06 LC)
Outgoing tides can pull organisms out of the intertidal zone and into the open ocean. How does this limit the number of organisms that can live in the intertidal zone?
Competition remains at a steady level.
Returning to the habitat is difficult.
The salinity increases.
The water quality changes.
Question 15(Multiple Choice Worth 3 points)
(03.01 MC)
Cod grow and reproduce best when the temperature is below 54 degrees Fahrenheit. The following graph shows the temperature anomalies from 1960 to 2015. Temperature anomaly refers to the way in which the temperature is different from the long-term average. If the anomaly is negative, that means the temperature is lower than normal; if the temperature anomaly is positive, the temperature is warmer than normal.
Graph shows the average global sea surface temperature from 1880-2014 in degrees Fahrenheit. In 1880, the sea surface temperature average was -0.5 degrees Fahrenheit. In 2010, the sea surface temperature average was 0.4 degrees Fahrenheit.

According to the graph, what prediction can be made regarding the ecosystem in which cod live?
Cod will need to relocate because of the warming waters of their ecosystem.
Cod will need to move farther south to grow and reproduce in large numbers.
Cod will need to move farther north to find the nutrients they need to survive.
Cod will need to relocate to adapt to the cooling trend seen in the data.
The answers to the questions are as follows:
Question 1: Invalidate, because energy should not leave a closed system
Question 2: An open system exchanges both energy and matter with its surroundings, and the scientist did not measure the movement of matter.
Question 3: Absorption
Question 4: an open system
Question 5: The energy is transformed to vibrational energy in the sand, rocks, and air.
Question 6: During low tide, the ocean water becomes concentrated, increasing salinity.
Question 7: Diurnal
Question 8: There is more food in northern regions during the summer.
Question 9: Wave height
Question 10: The time it takes for successive crests to pass through a point
Question 11: Constructive
Question 12: Returning to the habitat is difficult.
Question 13: Cod will need to move farther north to find the nutrients they need to survive.
