Answer:
stress caused by plate movement
Stress caused by plate movement is the main cause of an earthquake. So, the correct option is C.
What is an earthquake?A abrupt discharge of energy in the Earth's earth's crust that results in seismic waves causes an earthquake, which is the shaking of the planet's surface.
Sudden movement along Earth's fault lines causes earthquakes. The motion releases "elastic strain" energy that has been accumulated in the form of seismic waves, which travel through the Earth and cause the earth to tremble.
The primary cause of an earthquake is stress brought on by plate movement. Buildings, dams, etc. can sustain significant damage as a result of earthquakes. They might also bring about tsunamis, land slides, floods, and fatalities. A disturbance deep within the earth's crust is the reason behind it.
Therefore, the correct option is C.

Flagellates are microbes that have a rod-shaped flagellum that helps with their locomotion. Certain flagellates reside inside termites. These flagellates provide enzymes for the termites to digest cellulose, which helps them survive. In turn, the termites provide nourishment to these flagellates. Termites need cellulose for their survival, and flagellates obtain nutrition only from termites. Which statement can be true about the association between these microbes and termites?
A.
The flagellates share a facultative mutualistic association with the termites.
B.
The flagellates and termites share an obligate mutualistic association.
C.
The flagellates share an obligate parasitic association with the termites.
D.
The flagellates and termites share a commensal association.
E.
The flagellates and termites share a facultative parasitic association.
Answer:
B.
The flagellates and termites share an obligate mutualistic association
Explanation:
Organisms of same or different species tend to interact with one another in an ecosystem. The close interaction between two organisms is referred to as SYMBIOSIS. A type of symbiotic relationship is MUTUALISM, which is when both organisms benefits from the relationship.
However, mutualistic relationship can be of different types depending on how dependent the involved organisms are on each other. The example in this question illustrates OBLIGATE MUTUALISM, which is when the organisms involved in the mutualistic relationship depend on one another for survival. This is the case of the termites and the flaggelates where the termite depends on the flaggelate for enzymes that helps them digest cellulose while the flaggelates depend on termite for nourishment/food.
The termite will not survive if it doesn't get enzymes to digest its cellulose while the flaggelates will also not survive if they do not get nourished. Hence, the two organisms share an OBLIGATE MUTUALISTIC RELATIONSHIP.
Termites and flagellates have an obligate mutualistic relationship where the flagellates digest cellulose for the termites, and termites provide habitat and food for the flagellates.
Explanation:The association between termites and flagellates is described as an obligate mutualistic relationship. In this symbiosis, both parties are entirely dependent on each other to survive. The flagellates aid in the digestion of cellulose which is the primary food source of the termite. These protozoans possess bacteria that produce an enzyme called cellulase which is necessary for the breakdown of cellulose into sugars the termite can absorb. Conversely, the flagellates depend on the termites to provide them with a safe habitat and consistent food supply derived from the cellulose-rich wood that termites consume.

Why does Ocean City MD. have warmer winters than Sterling VA?
Final answer:
Ocean City, MD experiences warmer winters than Sterling, VA due to its proximity to the ocean, which moderates temperatures through the process of oceanality, while Sterling experiences more extreme temperature fluctuations due to continentality.
Explanation:
The reason Ocean City, MD has warmer winters than Sterling, VA can be attributed to the phenomenon known as oceanality, which is influenced by the proximity to the coast and the regulation of temperature by the ocean. In contrast, Sterling, VA experiences more continentality, which results in greater temperature fluctuations. The ocean impacts temperature on nearby coasts by warming the air in winter and cooling it in summer because water has a high heat capacity and changes temperature more slowly than land.
Oceans and large bodies of water like the Atlantic Ocean near Ocean City moderate temperature because they absorb heat during the warmer months and release it during the cooler months. This creates a milder climate with less extreme temperatures compared to inland areas. As Sterling, VA is located further inland, it lacks this moderating influence and thus experiences colder winters.

A skier is going down a hill at an initial velocity of 9 m/s East. The hill gets steeper and the skier's velocity increases to 18 m/s
East in 3 seconds. Find the acceleration.
MEANING
Answer:
Acceleration is 3m/s2
Explanation:
From the question, the formula for acceleration is ∆velocit÷∆time.
V1=9m/s
V2=18m/s
T1=0 seconds
T2=3 seconds.
V1 represent initial velocity
V2 represent final velocity
T1 represent initial time
T2 represent final time.
Acceleration=v2-v1÷T2-T1
=18-9/3-0
=9÷3
=3m/s2.
Acceleration is 3m/s2.
Acceleration is the rate of change of velocity of a body per unit time.
The acceleration of the skier is 3 m/s² eastward, calculated by dividing the change in velocity (9 m/s) by the time interval (3 s).
Explanation:The question involves finding the acceleration of a skier who increases their velocity from 9 m/s to 18 m/s eastward over a time interval of 3 seconds. To find acceleration, we use the formula a = ∆v / ∆t, where ∆v is the change in velocity, and ∆t is the change in time. The change in velocity (∆v) is 18 m/s - 9 m/s = 9 m/s. The change in time (∆t) is 3 seconds. Therefore, the acceleration (a) is 9 m/s ÷ 3 s = 3 m/s² eastward.
The skier's acceleration can be calculated using the equation:
a = (vf - vi) / t
where a is the acceleration, vf is the final velocity, vi is the initial velocity, and t is the time interval.
In this case, the initial velocity is 9 m/s East, the final velocity is 18 m/s East, and the time interval is 3 seconds.
Plugging in these values, we get:
a = (18 m/s - 9 m/s) / 3 s = 3 m/s² East
Therefore, the acceleration of the skier is 3 m/s² East.
An invasive species is a non-native species that lives in a region. Human activity has accidentally or intentionally introduced many invasive species into ecosystems. Name two human activities that could contribute to the introduction of invasive species. Explain your response.
1. Intentionally taking species over to another place. Think smuggling animals over, you might think a squirrel is cute and bring it home from your trip to Paris back to the US. That squirrel can now be an invasive species. Don't be spiderman and take a banana on the plane!
2. Unintentionally carrying a species over. This can be on boat propellers, water tanks in boats, airplane wheels, etc. Getting animals stuck in transportation can become invasive.
Answer:
Human travel can lead to an increased risk of invasive species. Native species—both animals and plants—can stow away on cars, trains, boats, and airplanes that bring them to another ecosystem. Climate change also can play a role. Human activity causes increased levels of carbon dioxide and other greenhouse gases in the atmosphere, which in turn creates an increase in global temperatures. Because all species are adapted to a specific climate, climate changes can result in non-native species spreading into other ecosystems.

What is the function of heart valves?
They return blood to the heart.
They force blood to flow out of the heart.
They regulate the heart rhythm.
They prevent blood from flowing backwards.
Answer: EDUCATED GUESS
Explanation:
They regulate the heart rhythm.
Heart valves prevent blood from flowing backwards, ensuring unidirectional flow that is essential for effective blood circulation throughout the body.
Explanation:The function of the heart valves is crucial for the cardiovascular system, as they prevent blood from flowing backwards by ensuring unidirectional flow through the heart. There are four valves in the heart: the tricuspid valve, the pulmonary valve, the mitral valve, and the aortic valve.
These valves open to allow blood to move forward and close to prevent it from leaking back into the chamber it came from. This action is vital as it maintains the efficiency and pressure necessary for blood to reach all parts of the body. The unidirectional flow is necessary for efficient circulation, ensuring that oxygen-rich blood reaches the systemic circulation and deoxygenated blood reaches the lungs for oxygenation.

When a blacksmith is working with hot metal, what places does the thermal energy go?
Question 15 options:
The thermal energy in the hot part of the metal moves to the cold part of the metal.
The thermal energy is transferred to the anvil and hammer.
Heat escapes into the air through convection.
All of the above.
None of the above.
Answer:
The thermal energy is transferred to the anvil and hammer.
Explanation:
In metallurgical processes, part of the thermal energy present in the hot metal is transferred to the anvil and the hammer. This is because the anvil and the hammer have different temperature than the temperature of the hot metal. With that, part of the thermal energy of the metal will be transferred to the hammer and the anvil, in an attempt to balance the thermal energy in the 3 objects.
Final answer:
When a blacksmith is working with hot metal, the thermal energy can go to the cold part of the metal, to the tools, and to the air.
Explanation:
When a blacksmith is working with hot metal, the thermal energy can go to several places. First, the thermal energy in the hot part of the metal moves to the cold part of the metal through conduction. This happens because the atoms in the hot part of the metal vibrate more and transfer some of their energy to the neighboring atoms in the colder part. Second, the thermal energy can be transferred to the tools used by the blacksmith, such as the anvil and hammer, through conduction. Finally, some of the thermal energy can also escape into the air through convection, where the hot air rises and carries away some of the heat.
Jonathon tests four people that were present during a shooting incidence. He notes that there is gunshot residue on all but two of the people, the victim
and another person. What might he conclude about the person with no gunshot residue on his hands or clothing?
O A. The person was next to the shooter.
OB. The person was the shooter.
Oc.
The person was not the intended victim.
OD.
The person was not beside the shooter.
O E.
The person struggled with the shooter.
Final answer:
Given the absence of gunshot residue on one individual besides the victim at the scene, the most likely conclusion is that this person was not beside the shooter when the gun was fired. D. The person was not beside the shooter is correct.
Explanation:
When Jonathan discovers that gunshot residue is absent on one of the people at the shooting scene, it suggests a few possibilities, but with the options provided, one stands out. Given that the victim also didn't have gunshot residue, it's reasonable to infer that someone not involved with the gunfire itself would likely be free from residue. Therefore, the absence of residue on another individual could indicate that they were not in proximity to the shooter when the gun was discharged. Interpreting evidence requires careful thought and consideration of all potential scenarios.
The most fitting conclusion from the given options is that this person was not beside the shooter. This would be consistent with the expectation that someone standing close to the shooter might have residue on them from being in close vicinity to the fired weapon. Hence, the correct option is:
OD. The person was not beside the shooter.

b.) 50 percent (half of the DNA)
c.) none of it
Answer:
B
Explanation:
Gametes are haploid that contains 1 set of chromosomes.
To form a zygote, fertilisation occurs which causes the fusion of a sperm and an egg to form a diploid cell.
In each gamete, they contain 50 percent of the genetic material as compared to the zygote, fusing to form a zygote with 100 percent DNA after fertilisation.
Why was the continental drift theory rejected at the time of its proposal?
A) It did not explain the mechanism causing the movement of continents.
It did not explain the mechanism behind the discovery of continents.
It did not explain the mechanism behind the existence of continents.
D) It did not explain the mechanism causing the formation of continents
Answer: Option A.
It did not explain the mechanism causing the movement of continents.
Explanation:
The continental drift theory was proposed by A geophysicist Alfred wengener In 1912 but it was rejected by many scientists due to lack of motion mechanism. This theory explained why Continent shift position on the Earth surface. It was rejected because there was not scientific evidence to prove how continents move.
The continental drift theory proposed by Alfred Wegener was initially rejected because it did not provide a satisfactory explanation for the mechanism responsible for the movement of continents. It wasn't until the development of plate tectonics in the mid-20th century that the concept of moving continents became generally accepted.
Explanation:The continental drift theory was first proposed by Alfred Wegener in 1912. This theory suggested that the continents were once joined together in a single landmass and have since drifted apart. However, this proposal was largely rejected by the scientific community at the time.
One of the main reasons for its initial rejection was that Wegener could not provide a satisfactory explanation or mechanism to account for the movement of the continents. Although he proposed that the continents 'ploughed' through the ocean floor, this was deemed to be physically impossible with the understanding of physics at the time. Therefore, despite some matching geological and palaeontological evidences between different continents, the lack of a plausible mechanism for the drift led to the rejection of Wegener's theory.
It wasn’t until the mid-20th century with the development of plate tectonics, where scientists understood that the crust of the earth is broken into plates that move relative to each other, that the idea of continents moving became widely accepted.

A person with an incomplete chromosome is missing many genes. This condition is known as aneuploidy and can lead to serious developmental issues or non-viability, notably in the case of monosomy where an entire chromosome is absent.
A person with an incomplete chromosome is missing many genes. An individual with the correct number of chromosomes is referred to as euploid. However, an aneuploid example, such as monosomy, involves the loss of one chromosome, leading to a deficit of essential genes required for development and survival. Autosomes are non-sex chromosomes, and monosomic zygotes missing an autosome usually do not survive to birth. For sex chromosomes, abnormalities can lead to milder conditions since cellular mechanisms inactivate all but one X chromosome. A common example is trisomy of chromosome 21, which results in Down syndrome, a genetic imbalance that can cause physical and developmental delays.
