it’s melting
From the diagram of the rock cycle the missing part is ( B ) ; Melting
Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.
Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting
Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.

what is the difference between fraternal twins and identical twins in terms of gene reproduction?
Answers
Answer:
Fraternal twins are dizygotic and Identical twins are monozygotic.
Explanation:
Fraternal twins are dizygotic, meaning that they developed from two different eggs fertilized by two different sperms. Their genetic code is as similar (or dissimilar) as any other siblings. Identical twins are monozygotic, meaning that they developed from the same fertilized egg, and so have nearly identical genetic code.

How does passive transport come into play in oxygen's journey through our body?
Answers
In the alveoli of the lungs, oxygen frequently diffuses from the air into the erythrocytes and blood plasma.
What is passive transport?Diffusion is a form of passive transport where molecules migrate from a high concentration to a low concentration, if you didn't know. Therefore, it follows that the oxygen content of the air must be higher than that of the blood.
Passive membrane transport methods are the most direct. Passive transport is a phenomenon that happens naturally and doesn't require the cell to use energy to move.
Diffusion is the process by which chemicals travel passively from a region of higher concentration to a region of lower concentration.
Therefore, Passive transport is a term that refers to both osmosis and diffusion. They don't need any power.

(Savannas)
(Both Types of
Grasslands)
(Temperate

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.

pls 3-5 sentence and then explain briefly the answer. ty
Answers
Answer:
1. There's air pollution, water pollution, noise pollution, and light pollution. The worst pollution is air pollution because it can cause severe health problems like respiratory diseases or even cancer.
2. Fossil fuels are resources that are formed from the remains of dead plants and animals. An example would be coal, oil, and natural gas. These fuels are used to generate electricity, power vehicles, heat homes and buildings. Yes, there many other energy sources that can replace fossil fuels.
3. One way to prevent factories from dumping waste water in rivers and oceans is to implement stricter regulations and penalties for those who violate them.
4. One of the best ways to reduce the amount of garbage is to reduce, reuse, and recycle.
5. Yes, I drink bottled water because it's more water to drink from a bottle and its effect on the environment is recycling and being reused.
1. Pollution can be of many types such as air pollution, water pollution, noise pollution, and land pollution. In my opinion, air pollution is the worst because it affects people's health and can cause breathing problems, heart diseases, and even cancer. Discussing this issue in a group can help us understand different perspectives and find solutions to reduce pollution.
2. Fossil fuels are non-renewable sources of energy that are formed from the remains of dead plants and animals. Examples of fossil fuels include coal, oil, and natural gas. They are used to generate electricity, fuel vehicles, and heat homes. However, they are a major contributor to air pollution and climate change. Fossil fuels can be replaced by renewable sources of energy such as solar, wind, and hydro power.
3. Factories dumping waste water in rivers and oceans can have a negative impact on aquatic life and the environment. To prevent this, factories can treat their waste water before discharging it into the environment. Governments can also enforce strict regulations and penalties for factories that violate environmental laws.
4. To reduce the amount of garbage, we can follow the three R's - reduce, reuse, and recycle. We can reduce the amount of waste we generate by using reusable bags, bottles, and containers. We can also compost organic waste such as food scraps and yard waste. Recycling can also help reduce the amount of garbage by turning waste into new products.
5. I try to avoid drinking bottled water because it generates a lot of plastic waste that can take hundreds of years to decompose. Plastic waste can also harm wildlife and pollute the oceans. Instead, I use a refillable water bottle and fill it with tap water. Tap water is safe to drink in most developed countries and can be a more sustainable choice.

It does not change its position or direction.
The North Pole always points in the same direction in the northern sky, which is towards the North Star or Polaris.
However, the tilt of the Earth's axis in relation to its orbit around the Sun causes the amount of sunlight received by different parts of the Earth to vary throughout the year.

An important step in science is supporting a theory or idea with data. The questions we ask help determine the type of data we collect.In the warm up, you reviewed the equation to calculate kinetic energy. What question could you ask about kinetic energy which will include the variables that affect it?
Answers
Answer: Kinetic energy depends on m, v in the expression, 1/2xmxv²
Explanation:we can ask how kinetic energy is changing if velocity is doubled, how kinetic energy changes if velocity changes. you can change the value of m, v in each question you ask.
Kinetic energy is the energy stored in a moving object. Kinetic energy depends upon mass and velocity of an object. During warmup, the velocity changes which results in increased kinetic energy.
What is Kinetic energy?Kinetic energy is the energy an object which is under motion. For accelerating an object, we must apply a force. Application of force requires some work to be done. After work has been done on the object, energy has been transferred to the object, and the object will be moving with a new constant speed or velocity.
Formula for the calculation of Kinetic energy is as follows:
K.E. = 1/2 m.v²
where, K.E. = kinetic energy of an object
m = mass of an object
v = velocity of an object
Kinetic energy can occur in any direction. Kinetic energy depends upon mass of an object and its velocity. When an objects' mass doubles, its kinetic energy also doubles and when the objects' speed doubles, its kinetic energy quadruples.

Natural selection is to ensure that only the best individuals live. Natural selection does not allow the sick or the incapacitated to survive. But man does not have natural selection, only in some cases. There is also little natural selection on farms.
Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. For example, treefrogs are sometimes eaten by snakes and birds, evolving long necks has enabled giraffes to feed on leaves that others can't reach, giving them a competitive advantage.
