Parasitism
Answer:
C. Parasitism
Explanation:
Mutualism means both organisms benefit. An example of this is a bee and flower.
Commensalism means one organism benefits and the other is unaffected. An example of this is a whale and barnacles.
Parasitism means one organism benefits, and the other is harmed. An example of this other than mosquito and human is a dog and fleas.

When the solar system was very young, the sun was just being formed and planets had not yet been made. The solar system was mostly gas and dust. Which statement best explains how planets formed in the early solar system?
A.Planets formed from magnetism in space that interacted with light from the stars.
B.Planets formed from large asteroids that had broken apart.
C.Planets formed from molten metal in volcanic eruptions.
D.Planets formed from small amounts of debris that were attracted together because of gravity.
Answer:
Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. ... When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material. At the center, gravity pulled more and more material in.

Planets formed from small amounts of debris that were attracted together because of gravity.
D. Planets formed from small amounts of debris that were attracted together because of gravity.
A dense cloud of interstellar gas and dust formed our solar system roughly a billion years ago. A solar nebula—a whirling, swirling disk of material—was produced when this dust cloud collapsed. Gravity drew more and more material into the center. The sun was still forming and planets had not yet been created when the solar system was very young. The solar system consisted primarily of gas and dust.
D. Planets formed from small amounts of debris that were attracted together because of gravity.

Answer:
I'm assuming it's convection.
Explanation:
When heat is transferred to liquids and gases, they carry that heat energy with them, further spreading it.
Answer:
I'm not 100% sure but I think it's Convection I'm not sure but I know Convection is heat flux through liquids and gases.

Explanation:
Which situation is an example of heat transfer by radiation?
Answer:
This type of transfer takes place in a forced-air furnace and in weather systems, for example. Heat transfer by radiation occurs when microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed. An obvious example is the warming of the Earth by the Sun.
Answer:
the heat from the hotter to the colder region. Some common examples of Radiation are Ultraviolet light from the sun, heat from a stove burner, visible light from a candle, x-rays from an x-ray machine. All life on Earth depends on the transfer of energy from the Sun, and this energy is transferred to the Earth over empty space.

Relative Dating Using Index Fossils
Index fossils can help geologists compare rock at locations .
• First, geologists give a relative age to a layer at one location.
• Index fossils help identify where may have occurred.
• Then that layer can be to other locations.
The answer choices is layers, distance, compared, unconformities
Index fossils can help geologists compare rock Layers at Distance locations.
Index fossils help identify where Unconformities may have occurred.
Then that layer can be Compared to other locations.

Sound, earthquakes, and waves in water are mechanical waves because they require a physical ______________________ to transport energy.
Disturbance
Electromagnetic field
Location
Medium
Sound, waves are all propagation of energy. Transport of this energy require a physical medium. Thus option D is correct.
What is mechanical waves?Mechanical waves are a form of energy transfer by oscillation of matter and they require a medium to propagate. Sound wave is a longitudinal wave which is only passing through a medium of air. Air disturbance causes these sound waves.
Longitudinal waves are those where the direction of oscillation of matter is along the direction of propagation. Electromagnetic waves does not require a medium to travel.
Waves in water originates from the pressure difference in water earthquakes is caused by seismic waves which are transverse waves, where the oscillation of matter is perpendicular to the direction of propagation.
Hence, sound, earthquakes, and waves in water are mechanical waves because they require a physical medium.

1. What are the different ways tectonic plates move in relation to each other?
2. What landforms could be the result of converging plates? name a location where this occurs.
3. What landforms could be the result of diverging plates? Name a location where this occurs.
4. What major event could occur as the result of transforming plates? Name a location where this can occur.
5. if crust is constantly created at divergent boundaries, why isn't Earth getting larger?
Answer + Explanation:
1. The different ways tectonic plates move in relation to each other are:
convergent (where plates move into one another)
divergent (where plates move apart)
transform (where plates move sideways in relation to each other)
2. Convergent plate boundaries can result in:
earthquakes, volcanoes, and the formation of mountains.
The Himalaya Mountains are the result of convergent plate boundaries.
3. Landforms that are a result of divergent boundaries are rift valleys and mid-oceanic ridges.
Locations where this occurs are: Mid-Atlantic Ridge, Red Sea Rift, Baikal Rift Zone
, East African Rift, East Pacific Rise, Gakkel Ridge, Galapagos Rise, and Explorer Ridge.
4. Transforming plate boundaries results in shallow earthquakes, large lateral displacement of rock, and a broad zone of crustal deformation.
A location where this occurs is: San Andreas Fault in western California

Which is one way that minerals crystallize from materials dissolved in water?
from the air
from solutions that evaporate
from hot water solutions when water boils
from the soil
Answer:
B. from solutions that evaporate
Explanation:
I took the test
The minerals crystallize from materials dissolved in water from solutions that evaporate. Therefore, option B is correct.
What is mineral ?A mineral or mineral species is, generally speaking, a solid chemical compound that naturally occurs in pure form and has a very well-defined chemical composition as well as a particular crystal structure.
Each crystal structure that makes up a chemical compound that exists naturally as a separate mineral species. As an illustration, silicon dioxide is a component of the same mineral species as quartz and stishovite.
They can be mined and have the potential to be exploited as a source of metal. Manganese, iron ore, and bauxite are examples of metallic minerals, which can be either ferrous or non-ferrous. While ferrous minerals do contain iron, non-ferrous minerals do not.
Thus, option B is correct.
