Tsunamis are huge waves that carry large amounts of energy across the ocean. They are often caused by underwater earthquakes. One a tsunami forms, the wave can travel hundreds of kilometers before reaching land. Are the water molecules that touch land the same ones that the earthquake initially moved? Why or why not?
Answer:
Some of them yes but some of them no.
Explanation:
When the tsunami moves across other bodies of water it initially gets bigger. When it is moving across the water it is picking up molecules as well as dropping them off. But the farther away the tsunami gets from the water the smaller it gets.
Some of the water on land may be initaited by earthquake or may be not.
What is tsunami?Tsunami is a natural disaster, which causes the large destroy of natural lands, forests, habitats of many living beings, etc.
As it is mention that tsunami is caused by the earthquake which is occured underwater and as a effect of this, waves of ocean can travel hundreds of miles before touching the land. So, it is not necessary the water molecules which touches the land after this disaster is always that ones which are initiated by the earthquake.
Because during the travelling process may be some water will again drop off in the ocean or some may get evaporate.
Hence, it may be the water initiated by the earthquake or may be not.

How are mixtures and solutions different?
1.Unlike a solution, a mixture has density and will always sink in a liquid because mixtures lack buoyancy.
2.Unlike a solution, a mixture can dissolve completely in a liquid because the properties of the ingredients change.
3.Unlike a solution, a mixture is unable to change states of matter from a solid to a liquid or gas.
4.Unlike a solution, a mixture can easily be separated and each ingredient keeps its physical properties.

Which statements accurately describe parasite-host relationships? Check all that apply.
Parasites can live in or on their hosts.
Parasites benefit from their hosts.
Parasites are harmed by their hosts.
Parasites usually kill their hosts.
Hosts benefit from parasites.
Hosts are harmed by parasites.
Parasites can live in or on their hosts, they benefit themselves from their hosts and usually kill their hosts and hosts are harmed by parasites this is called parasitism.
What is Parasitism?A parasitism is a kind of symbiotic relationship in which two species lives in close association. In this association one species is benefited by harming the other species so as to derive nourishment and shelter. The species which causes harm is called as the parasite the species which is being harmed is called as host. In parasitism the parasitic as well as the host species evolve together. The parasite is adapted to live in the host body in adverse conditions too. Also the host is adapted to get rid from the parasite and attain a protection from the parasitic damage.
Therefore, first, second, fourth and sixth statements are correct.

How could you use a model to show the cause-and-effect relationship between Earth's rotation and the apparent motion of the stars across the night sky?
Question:
How could you use a model to show the cause-and-effect relationship between Earth's rotation and the apparent motion of the stars across the night sky?
Answer:
Gravity? or density because of the pull from the sun.
We can describe the cause-and-effect by showing the rotation of earth and its effect on the apparent motion of the stars across the night sky.
What is rotation of Earth?Rotation of earth means, spinning motion of earth at its own position as a result of which day and night will occur.
Because of the motion of earth will night occur and at the night time stars will travel from east to west direction. And polar starts will rotate with the pole star at center making a circular trial.
Hence, the above model is used.

Water, copper ferrous sulphate and potassium chloride are the compounds. Therefore, option A, B and E are correct.
What are compounds ?A chemical compound is a substance that contains atoms from many chemical elements bonded together by chemical bonds. It is made up of numerous similar molecules. Therefore, a molecule made up of only one type of atom is not a compound.
When various atoms are linked or chemically bound together to form molecules, the result is a compound. Water is an example of a compound. Due to the chemical bonding of two hydrogen atoms and one oxygen atom, water is known chemically as H2O.
Substances that cannot be divided into less complex substances with differing properties are known as elements. The periodic table is an arrangement of elements according to their properties. A molecule is made up of two or more atoms. Compounds are molecules made up of more than one element.
