Waves move faster in higher temperature and in solid phase because there is more energy and the particles are closer together.
What is meant by intermolecular force ?Intermolecular force is defined as the force of attraction experienced between the neighboring molecules in the same state.
Here,
During higher temperature and when in a solid phase, the waves exhibit movements very faster than in other phases.
This is because, when the temperature of the system is increased, the energy of the molecules in the system will be increased to a higher level. This energy formation is in the form of kinetic energy of the molecules.
Molecules in the solid phase have a greater intermolecular force of attraction with their neighboring molecules. Therefore, the molecules in the system will be more closer to each other.
As the kinetic energy of the molecules in the system increases, the molecules will start vibrating. These vibrating molecules induces the vibration to their neighboring particles, since they are closer together.
As a result, more and more highly energetic molecules are set to vibrate, which causes the wave to move faster in the system.
Hence,
Waves move faster in higher temperature and in solid phase because there is more energy and the particles are closer together.

2. What structure caused rotifers to be called wheel animals or wheel bearers?
1 the foot
2 the corona
3 the brain
4 the stomach
The structure that caused rotifers to be called wheel animals or wheel bearers is the corona.
Rotifers are also known as wheel animals or wheel bearers because of the corona structure around their mouth region.
Some rotifers are sessile and live inside tubes or gelatinous holdfasts that are attached to a substrate. Other rotifers migrate around a substrate through inch worming.
This is because when corona is seen in a sequential coordinated movement, it resembles the structure of a wheel, although it does not rotate in reality.
Therefore, we conclude that rotifers are called wheel animals or wheel bearers due to the presence of the corona structure.

Write a complete scientific explanation to account for why the heavier ball caused more flour to spread out. Be sure to include the relationship between amount of mass and amount of kinetic energy in your explanation, and include a claim, evidence, and reasoning.
The heavier ball caused more flour to spread out because it possessed greater kinetic energy due to its greater mass.
What is kinetic energy ?Kinetic energy is proportional to an object's mass and velocity, and since both balls were dropped from the same height, they had the same initial potential energy.
However, the heavier ball had more kinetic energy as it hit the flour, causing it to displace more flour than the lighter ball. This can be observed in everyday situations, such as a heavier object causing more damage than a lighter object when dropped from the same height.
Therefore, the relationship between mass and kinetic energy can explain why the heavier ball caused more flour to spread out.

Which of the following are true about endergonic and exergonic reactions? Select all that apply. A) Endergonic reactions consume energy and exergonic reactions release energy. B) Both endergonic and exergonic reactions require a small amount of energy to overcome an activation barrier. C) Endergonic reactions have a positive delta G and exergonic reactions have a negative delta G. D) Exergonic reactions take place slowly and endergonic reactions take place quickly
D) The speed of endergonic reactions is faster than that of exergonic ones.
Energetic and exergonic reactions: what are they?In thermochemistry or physical chemistry, there are two different types of chemical reactions or processes: endergonic and exergonic. The names give an explanation of how energy is used up during the reaction.
The classifications are similar to endothermic and exothermic reactions, however endothermic and exothermic only apply to heat or thermal energy, whereas endergonic and exergonic describe what occurs with any form of energy.
Energy from the environment is absorbed during an endergonic process. As they absorb heat, endothermic reactions make for interesting illustrations. Citric acid and baking soda (sodium carbonate) should be combined with water.
Although the liquid will become chilly, frostbite won't develop. Energy is released into the environment during an exergonic reaction. Exothermic reactions are excellent illustrations of this kind of reaction since they produce heat.

Answer:
1) Weathering, Erosion, Disposition
2) Physical weathering is the breakdown of large rocks into fragments by physical forces; the chemical composition of the rock is not changed. Chemical weathering is the breakdown of rock by chemical reactions; the chemical composition is changed.
3) The four forces of erosion are water, wind, gravity, and glaciers.
4) Because the velocity of the river slows down a great deal when it reaches the large body of water, the sediment that the river was carrying is deposited along the mouth of the large body of water.
--------------------------------------------------------------------------------------------------------
Abrasion: Abrasion is the breaking down and wearing away of rock material by the mechanical action of another rock. Three agents of physical weathering that cause abrasion are moving water, wind, and gravity. Also, rocks suspended in thence of a glacier can cause abrasion of other rocks on Earth's surface. This would be a prime example of physical weathering, or mechanical weathering.
----------------------------------------------------------------------------------------------------------
Acid Precipitation: Acid rain causes less erosion than normal rainwater does. Rainwater can break down rocks by dissolving minerals in the rocks. Acid rain is rainwater that is more acidic than normal rainwater. Acid rain can also dissolve the minerals in rocks faster than normal rainwater can. This is chemical weathering.
--------------------------------------------------------------------------------------------------------
Animal actions: Animal and plant mobility is a factor in biological weathering. For instance, a plant may grow in a gap in a rock and, as its roots spread, cause the fracture to expand. A rabbit may also burrow into a crack in a rock, making it wider and eventually separating the rock. This is an example of physical weathering.
---------------------------------------------------------------------------------------------------------
Ice wedging: Ice wedging ,sometimes known as frost wedging ,can also cause rocks to break apart. Ice wedging causes cracks in rocks to expand as water seeps in and the water freezes and expands opening the crack further. Rocks formed under pressure deep within earth can become exposed at the surface. This is physical weathering
----------------------------------------------------------------------------------------------------------
Oxidation: Oxidation is another kind of chemical weathering. It occurs when oxygen from air dissolves in water and combines with chemicals in the rocks to form oxides. if the rock contains a lot of iron, then oxidation produces a brown material called iron oxide. This looks like rust on the rock.
What is the difference between weathering erosion and deposition?Weathering is the chemical and mechanical breakdown of exposed rock. The chemical changes alter the minerals and make them softer, and mechanical weathering physically breaks rock into smaller and smaller pieces.
Erosion is the REMOVAL of those chemically and mechanically softer and broken pieces of rock from their original locations, by gravity, water, ice or wind. Erosion is transport (and as a result, fresh unaltered rock is exposed to wind, water and weather, and THAT becomes weathered in turn). The material being transported is ‘sediment’: sand, silt, mud and gravel.
Deposition is when the weathered and eroded (transported) material is dropped and settles down elsewhere, forming a ‘deposit’ of transported rock material.
If this deposit remains undisturbed long enough, and is buried by enough arriving material, it will eventually go through compaction and chemical reactions forming cement between the grains - thus resulting in a brand new, sedimentary rock.
Weathering, erosion, transport, deposition, compaction and cementation are part of the ‘rock cycle’.
How can the complete rock cycle be described?Let’s start with basalt that form at mid ocean spreading centers. At mid ocean spreading centers rock material from the earth’s mantle continuously melts due to continuous decreasing in pressure from the oceanic crust spreading at this point. The molten rock quickly cools at the earth’s surface and forms rock known as basalt that makes up the oceanic crust all over the world. The newly produced oceanic crust rock slowly moves towards a boundary with a continental crust where the oceanic crust subducts beneath the continental crust due to the oceanic crust having a higher density than the continental crust. This is where things get a bit more interesting.

Physical oceanography is one of several sub-domains into which oceanography is divided. Others include biological, chemical and geological oceanography.
Chemical oceanography is a broad and complex study of the metamorphosis that the chemicals within oceans, living marine organisms, and the ocean floor undergo. The ocean contains a multitude of chemicals; some are natural, and others are man-made. These chemicals enter the sea in a number of ways.
Biological oceanography is a field of study that seeks to understand what controls the distribution and abundance of different types of marine life, and how living organisms influence and interact with processes in the oceans.

Why do large scale mutations have such a significant effect on organisms?
Large-scale mutations can have a significant effect on organisms because they involve changes in the DNA sequence that affect the function or expression of one or more genes.
These mutations can result in changes to the structure or function of proteins, which are the building blocks of cells and perform many critical functions in the body.
In some cases, large-scale mutations can also affect multiple genes or entire genetic pathways, leading to more widespread effects on an organism's physiology or behavior. This can result in reduced fitness, decreased survival, or even extinction in some cases.
