The statement "the chaparral biome is generally characterized by its terrain" is absolutely false.
What is a Biome?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.

Explanation:
Atom A has six protons , five neutrons and five electrons. Atom B five protons , six neutrons, and five electrons . Are atoms A and B of the same element ?
1. no, because they do not have the same number of protons
2. no, because they do not have the same number of neutrons
3. yes , because they have the same number of electrons
4. yes , because both have 16 protons , neutrons, and electrons combined
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 .

Genes code for specifically structured
sugars.
acids.
lipids.
proteins.
Genes code for specifically structured proteins. The majority of genes have the necessary instructions to produce the useful molecules known as proteins, hence option D is correct.
The segment of DNA needed to make one protein is known as a gene, because they code for proteins consisting of hundreds or thousands of amino acids, genes often have hundreds or thousands of base pairs.
The ribosome, a specialized complex that "reads" the sequence of mRNA nucleotides, interacts with the messenger RNA (mRNA). A codon is a group of three nucleotides that typically codes for one specific amino acid.

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.
What do you mean by perpetual resource?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.

From the list below, select all the probable items that make up the core. (Select all that apply.)A.IronB.AluminumC.SodiumD.MagnesiumE.Nickel
Answer: A. Iron and E. Nickel
Explanation:
Earth's core is the center part of the planet and it is very hot in nature. It is the center of geothermal activities. It is like a furnace. It is associated with intense heat and pressure in the center. It is composed of iron and nickel. The crust and mantle are rich in many minerals. The core is made up of outer core and inner core. The outer core is in borders with the mantle. The temperature of the inner core is higher than the melting point of iron.
the particles of a gas are
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.

select the best answer that describes how lionfish are impacting biodiversity in Florida. O Lionfish are consuming large quantities of plankton, a vital part of the food web O Lionfish are competing with large sharks for prey Lionfish are rapidly consuming many smaller fish species along the coast at depths up to 90 meters. Lionfish are consuming the majority of the shrimp populations near the coast, as it is their only food source
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.
