Answer:
When a solid is heated the particles gain energy and start to vibrate faster and faster. Further heating provides more energy until the particles start to break free of the structure. Although the particles are still loosely connected they are able to move around. At this point the solid is melting to form a liquid.

When one gram of liquid water at its boiling point is changed into water vapor
Answer:
Water needs 40.65 kJ/mole of energy.
Explanation:
One gram of liquid water changed into water vapor at its boiling point, energy is required called the heat of vaporization. Water has a heat of vaporization of 40.65 kJ/mol. Hydrogen bonding is present between water molecules so to break this hydrogen bond, heat energy is required. This heat energy is different for different liquids, water needs 40.65 kJ/mole of energy to break the bond and change into vapors.
What are the two types and functions of vascular tissue?
Answer:
Vascular tissue transports water, minerals, and sugars to different parts of the plant. Vascular tissue is made of two specialized conducting tissues: xylem and phloem. Xylem tissue transports water and nutrients from the roots to different parts of the plant, and also plays a role in structural support in the stem. Phloem tissue transports organic compounds from the site of photosynthesis to other parts of the plant. The xylem and phloem always lie adjacent to each other in a vascular bundle

Landslide is an inevitable process in hilly areas. Do you agree with this statement? Why?
Answer:
In hilly areas, the landforms are generally sloped and heavy rainfall loosens the material. When the right combination of materials, moisture, and steepened slope angle (i.e. increased gravity) makes a hillside unstable, a slide or flow is inevitable.

Research the fossil record of humans and answer these questions:
Name at least two extinct species that share a close evolutionary relationship with humans.
Explain the similarities and differences that exist between these species and humans.
Is the fossil record complete for humans? Explain your answer.
Answer:
here is ur answer
Plzzz mark me as brainliest
Answer:
Paranthropus and Giantopithecus are two extinct species that have close evolutionary ties to humans. Paranthropus is an extinct genus of extinct hominin, while Giantopithecus is an extinct genus of ape. Hominins and apes share at least 95% of their DNA with humans, so these two extinct animals probably had some evolutionary ties to humans. Humans walk on two legs and have the ability to speak, whereas both extinct animals walked on four legs. Humans and these extinct animals also share similar body makeup and bone structure. The fossil record of humpback whales is probably incomplete because everything is continuously changing due to evolution.

Large shrubs and trees are often planted near rivers to help prevent flooding. The deep, highly-absorbent roots of these shrubs and
trees help soak up heavy rains before they begin to flood the land. Because they reach high above the ground and their branches
and leaves spread outward, trees can also reduce the amount of rainfall that reaches the ground by up to 45%. In the event of a
flood, what additional benefit might these shrubs and trees provide?
They store and hold excess water to prepare for dry seasons:
B)
They prevent flood waters from entering and polluting the rivers.
O
They help to slow down the flow of water, reducing damaging impacts.
D)
They absorb harmful pollutants and stop debris from entering the river.

What resources does your body require to sustain basic levels of nonathletic activity?
Answer:
Remember: Athletes need more food and fluids than non-athletes. Regular meals and healthy snacks will help fuel your body before and after exercise. It's important to give your body enough of the right fuel in order to feel good and have the energy you need to perform your best.
The human body requires several resources to sustain basic levels of non-athletic activity. These are mentioned below.
What are non-athletic activities?Non-athletic activities refer to activities that do not involve significant physical exertion or athletic performance. These activities can include a wide range of daily tasks and routines.The important resources are mentioned below:
Energy: The body needs energy to perform all of its functions, including breathing, pumping blood, and maintaining body temperature.Water: The body is about 60% water, and water is essential for many bodily functions, including regulating body temperature, transporting nutrients and oxygen, and removing waste products.Oxygen: The body requires oxygen to produce ATP through cellular respiration, which is the process by which cells convert glucose and oxygen into energy.Macronutrients and Micronutrients: The body requires macronutrients and micronutrients such as carbohydrates, proteins, and fats to provide energy and build and repair tissues.Learn more about non-athletic activities, here:

How does water heat Earth?
O Water traps heat and holds it deep inside the ocean.
O Water transports nutrients and waste.
O Water carries heat from the equator toward the poles.
O Water from rainfall on land starts in the ocean.
The water traps heat and holds it deep inside the ocean.
Water carries heat from the equator toward the poles. This is one way that water can heat the Earth. This is because the ocean has a significant impact on Earth's climate. The correct option is C.
How does water transfers heat?Ocean currents transport heat from the tropics toward the poles, and this helps regulate the Earth's temperature. This is why regions near the coast are often more moderate in temperature than regions located inland.
Another way that water can heat the Earth is through the greenhouse effect. Water vapor is a greenhouse gas, which means that it helps trap heat in the Earth's atmosphere. This is important because if the Earth were not warmed by the greenhouse effect, it would be much colder and uninhabitable.
Finally, water also heats the Earth by storing heat deep inside the ocean. This heat can be transported to the surface through ocean currents or released into the atmosphere over time. Overall, water plays a significant role in heating the Earth and regulating its climate.
Therefore, the correct option is C.

Gavin learns in science class that small objects such as meteoroids and debris can move through space at such high speGavin learns in science class that small objects such as meteoroids and debris can move through space at such high speeds that they can damage or puncture the sides of space vehicles. He decides to design an experiment based on this information. Gavin uses an empty shoe box, a sheet of paper towel, and tape to build a model of a spacecraft. Then, he shoots a pea at the paper towel part of the model using a straw pea shooter. For his first trial, Gavin shoots a 3.0-gram pea at the model. Its speed is measured at 12 meters per second as it leaves the straw. The pea does not break the paper towel, but it bounces back off and lands on the ground.eds that they can damage or puncture the sides of space vehicles. He decides to design an experiment based on this information. Gavin uses an empty shoe box, a sheet of paper towel, and tape to build a model of a spacecraft.
