Existing rocks are buried and forced toward the mantle, increasing heat and pressure. This is the first step in the formation of metamorphic rocks.
(PLEASE HELPPPP 90 POINTS!!)
Which best describes the next step in the formation of metamorphic rocks?
Buried rocks melt deep within the mantle.
Lava melts underlying rocks, which crystallize into new minerals.
Rocks that were buried are exposed at Earth’s surface, where they are weathered and eroded.
Magma pockets rise, which increases heat, and minerals change due to temperature and pressure.
Answers
The correct answer is B. When buried rocks are forced toward the mantle, they undergo extreme heating and pressure, which can cause them to melt. This molten rock is known as magma, which then crystallizes as new minerals as the magma cools and solidifies. This process is known as metamorphosis and is the second step in the formation of metamorphic rocks.
Buried rocks melt deep within the mantle.
Mechanical energy can take on many forms, but these different forms can be categorized as either potential energy or energy of motion. The height an object is dropped from has an effect on the amount of energy in the object. Let’s conduct an experiment to see the effect.
:How does the height of an object affect the amount of mechanical energy it contains?
1:Variables What is the test variable?
Answers
The height of an object is crucial to the amount of energy something has because the higher up it is the most potential energy it has and kinetic energy it could have.
For example, if the height of a basketball was just a couple inches off the ground, it would not have a large amount of potential energy because because there is not much of a fall between the ball and the ground. However, if the ball was higher, there would be more potential energy because there is more room to fall.
---
"What is the test variable?"
The test variable, or independent variable in this case would be the height, as the scientist is changing the height in order to get different results in the total mechanical energy, which would be the dependent variable.

What best describes ribosomes?
Answers
Ribosomes are cellular structures that synthesize proteins from amino acids. They are composed of ribosomal RNA and proteins and are found in both prokaryotic and eukaryotic cells.
Ribosomes are essential for gene expression and cell growth. They can be free in the cytoplasm or bound to the endoplasmic reticulum or the nuclear envelope.
An example of a ribosome function is the translation of a messenger RNA (mRNA) sequence into a polypeptide chain. The ribosome reads the mRNA codons and matchesthem with the corresponding transfer RNA (tRNA) anticodons that carry the amino acids. The ribosome then forms a peptide bond between the amino acids and releases the tRNA. This process continues until the ribosome reaches a stop codon on the mRNA and terminates the protein synthesis.
Answer:
A ribosome is a intercellular structure made of RNA and protein

Models usually do not have exactly the same features as the objects or events that they represent.
Answers
Answer:
d
Explanation:
The answer would be d because limitation of models is basically about non realistic part of models that separate them from real life which is what d is saying.
The branch of science which deals with chemicals and bonds is called chemistry.
The correct option is D.
Whenever a scientist gave the theory, he has to prove it experimentally and prove its physical existence to the world.
He can use various ways to prove his theory. One of the several ways of them is model making.
In the model, he tries to convey all the points which he mentioned in his theory but in the actual case the real event and the observation found in the experiment are different and no model can give you the exact 100% result without any error.
Hence, the correct answer is D that is Models usually do not have exactly the same features as the objects or events that they represent.

How can you grow spiritually?
by being obedient to God
by making up your own rules
by being controlled by Him
by following Jesus' example
by doing only what you want to do
Pick all that apply!
Answers
Growing spiritually can involve different practices and beliefs for different individuals, but some ways to grow spiritually may include: - Being obedient to God and following His teachings - Seeking guidance and inspiration through prayer and meditation - Studying religious texts and teachings regularly - Practicing compassion and kindness towards others - Surrounding yourself with supportive and like-minded individuals - Reflecting on your thoughts, actions, and beliefs regularly and striving for personal growth and improvement Making up your own rules or only doing what you want to do may not necessarily lead to spiritual growth as it lacks guidance and accountability. Being controlled by God can also be interpreted in different ways, but ultimately, it is up to the individual to develop their own personal relationship with God and seek ways to grow spiritually.
Answer:
Spiritual growth can manifest in diverse practices and beliefs among individuals. However, common ways to foster spiritual development include obeying God and adhering to His teachings, seeking guidance and inspiration through prayer and meditation, regularly studying religious texts and teachings, demonstrating kindness and compassion towards others, seeking support from like-minded individuals, and engaging in self-reflection to pursue personal growth and progress. Contrarily, self-created rules or adhering solely to one's preferences may not facilitate spiritual growth, as it lacks accountability and direction. The interpretation of being controlled by God may vary; nevertheless, individuals must establish their unique personal relationship with God and explore ways to develop their spirituality.

Answers
Answer:
Here you go!
Explanation:
Crest -it is the highest point in the wave. Trough- it is the lowest point in the wave. Amplitude- It is the distance from the top to bottom of the trough. Wavelength- the horizontal distance between successive crests, troughs or other parts of a wave.
A wave is a disturbance that moves from one location to another through a medium.
What is Wave?The vibration of the thing or material that transports the wave creates waves. By creating a vibration at one end of a jump rope, you can create your own waves.
The wave you produce will flow across the rope from one end to the other. A wave is a disturbance that travels through a medium from one place to another. Waves are formed by the vibration of the object or substance that carries the wave.
Every wave is produced by a certain vibration. The medium is disturbed by vibrations, and this disturbance serves as the wave's source.
Therefore, A wave is a disturbance that moves from one location to another through a medium.

grasslands and share many characteristics, they also have
some differences. Compare them below by writing each
characteristic in the correct location. You will use each only
once.
• home to many types of grazers
• experience all seasons of weather
• home to bison
• home to the African elephant
• example: tallgrass prairies of North America
• example: Serengeti in Tanzania
• also known as tropical grasslands
• few trees due to little rainfall
1)
(Savannas)
(Both Types of
Grasslands)
(Temperate
Grasslands)
Answers
Answer:
S - Savannas are typically found in tropical or subtropical regions.
S - Savannas tend to have more trees and shrubs.
S - Savanna's climate is drier than that of a grassland.
G - Grasslands are found in temperature regions.
G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.
G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.
B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.
B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.
B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.

Describe how bacteria reproduce. How can bacteria acquire new characteristics?
Answers
Answer:
bacteria are found everywhere even in hot springs. Bacteria are different from other organisms because they don't have membranes bound organelles .they replicates to produce
Explanation:
Bacteria can live in hotter and colder temperatures than humans, but they do best in a warm, moist, protein-rich environment that is pH neutral or slightly acidic. There are exceptions, however some bacteria thrive in extreme heat or cold, while others can survive under highly acidic or extremely salty conditions.
How might bacteria avoid dying if an environment is not suitable?Many types of bacteria, if environmental conditions become unfavourable (lack of water, increase in temperature, etc), will go into a sort of dormant state, called an Endospore.
How are bacterial cells different from plant and animal cells?Because bacteria are prokaryotic, they do not have a nucleus and no membrane-bound organelles. In contrast, plants and animals are made up of eukaryotic cells, which means they have a nucleus and membrane-bound organelles like mitochondria or Golgi apparatus.
Describe how bacteria reproduce. How can bacteria acquire new characteristics?Bacteria reproduce through a process called binary fission. During binary fission, the chromosome copies itself, forming two genetically identical copies. Then, the cell enlarges and divides into two new daughter cells. The two daughter cells are identical to the parent cell.

Describe how heat moves in a convection current. How is this process responsible for moving earth’s tectonic plates?
Answers
Part 2: The Earth's crust is broken up into pieces called plates. The crust moves because of movements deep inside the earth. Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. The convection currents move the plates.
Explanation:
Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat. ... Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.
