Answer:

The last answer

Explanation:

The sun is a perpetual resource because solar radiation steadily streams from the sun without interruption and is expected to do so for the next 6 billion years.

Perpetual resources are those that last forever like solar energy and wind. Non-renewable resources, once extracted completely from a given area, will never be available in the same spot again (except after millions of years).

Perpetual resources are natural resources—such as solar energy, wind, and tides—that have no chance of being used in excess of their availability. They can be used for power generation and conversion to electric energy.

Sunlight, wind, geothermal heat, tides, and flowing water are perpetual resources. On Earth, there are only limited amounts of fossil fuels such as oil, coal.

Answer: Low Density

Gases contain scattered molecules that are dispersed across a given volume and are therefore less dense than in their solid or liquid states. Their low density gives gases fluidity, which allows gas particles to move rapidly and randomly past one another, expanding or contracting with no fixed positioning. The average distances between the molecules are large enough that interactions between molecules don't interfere with their motion.

Indefinite Shape or Volume

Gases have no definite shape or volume.The random movement of gas molecules allows them to expand or contract to assume the volume of the container holding them. Therefore, a gas's volume refers to the space of the container in which its molecules have range to move. This property results in gases occupying more space than they would in their liquid or solid state. Gases also contract and expand by predictable amounts depending upon changes in temperature and pressure.

Compressibility and Expandability

The low density of gases makes them compressible since their molecules can be positioned far apart from one another. This allows them to move freely to fit into the gaps of space between them. Just as gases are compressible, they are also expandable. The freedom of gas molecules causes them to take the shape of any container in which they are placed, filling the container's volume.

Diffusivity

Given the large amounts of space between gas molecules, two or more gases can mix quickly and easily with one another to form a homogeneous mixture. This process is called diffusion.

Pressure

Gas molecules are in constant motion. They exert pressure, or force per unit area, on the interior surface of their container. The pressure varies according to the amount of gas confined to a given container's volume, the temperature and the pressure.

Explanation:

These are the 5 properties of gas, they don't have particles, they have properties.

The statement "the chaparral biome is generally characterized by its terrain" is absolutely false.

A biome may be defined as a type of very large area which is characterized by a particular type of vegetation. In a more simple sense, it is a very large ecosystem that is running in nature in an unmanaged way. Examples may include tropical rainforests, coral reefs, grasslands, etc.

The chaparral biome is a type of biome that has hot and dry summers with mild and rainy winters. This biome receives about 38-100 cm. of precipitation in a year. It makes this biome most vulnerable to fire in the late summer and fall.

Therefore, the statement "the chaparral biome is generally characterized by its terrain" is absolutely false.

Answer:

I think because of the chemical reaction I think something to do with carbon dioxide but I forget

Answer:

no, because they do not have the same number of protons

Explanation:

No of protons represents atomic number which decides the characteristics of an atom . Two atoms having same number of protons but different number of neutrons are same element . They differ only in some physical characteristics . They are called isotopes . In respect of chemical properties they are same .  In a neutral element number of protons and number of electrons are same . But in some case number of electrons may differ . In that case they form ions of the element . In positive ion , number of electrons is shorter than number of protons .

In the present case , atom A and atom B differ in respect of number of protons so they represent different element .

Answer:

Lionfish are rapidly consuming many smaller fish species along the coast at depths up to 90 meters.

Explanation:

Lionfish is an invasive species that has been successfully established in the Atlantic Ocean. It is a tropical species that lives mostly in reefs and rocks that provide protection. It inhabits waters from the coast to 50 meters deep.

Because of its high densities in the Atlantic, Lionfish is a promoter of ecological, economic, socio-cultural consequences. They only have a few predators and consume a high diversity of prey items. They produce an ecological imbalance in the trophic chains of the marine ecosystem. When competing with native piscivores, they imbalance the dynamics of fish communities in coral reefs and mangroves. The density of young and herbivores fishes has decreased because of their predation by the lionfish. By predating on algae eating fishes, they provoke a sharp increase in algae populations, which produces serious damages in the coral reefs, enhancing their mortality. The main consequences of these damages are marine biodiversity loss, water quality decrease, ecosystem recovery difficulty, and impacts on food provisioning for many other ocean species.

Osmosis is the movement of water molecules through a selectively permeable membrane from high to low concentrations.  

Diffusion is the process in which molecules move from an area of high concentration to low concentration.

The statement doesn't say that the molecules are water, so we put false.  If it is wrong then tell the teacher that she has to include water molecules in there to be more detailed.

Answer: They are,

benthic zone or ocean floor and pelagic zone or ocean waters

Explanation:

The pelagic or ocean waters refers to the zone beyond the continental shelf and it is the zone where organisms swim or float. Organisms live and survive in this zone.

The benthic zone is the deepest part of the ocean and it is beyond the pelagic zones, some organisms live in this zone too but there are sediments or deposits in this zone of the ocean.
