shortly after world war ||, chickens were bred to grow much more quickly and produce more meat. what is this an example of?
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.
Where does FGF5 occur in the cell?
Answer: FGF5 is produced in the outer root sheath of the hair follicle as well as perifollicular macrophages, with maximum expression occurring in the late anagen phase of the hair cycle. The receptor for FGF5, FGFR1, is largely expressed in the dermal papilla cells of the hair follicle.

What happens when the net energy is zero
Answer: Zero Net Energy = Zero Net Emissions
Explanation: With the addition of renewable energy generation, a ZNE building's annual energy costs become negligible, and since there is a net-zero balance of energy production and use, your building's carbon footprint with respect to energy consumption would also approach zero.
Identify the two major zones of the ocean
environment
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.

In osmosis molecules move through a semi-permeable membrane from a high concentration to a low concentration. True or False
Answer:
False
Explanation:
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.

What type of resource is the sun and why?
The sun is a perpetual resource because solar radiation steadily streams from the sun now, but it will only do so for the next thousand years.
The sun is an unsustainable resource because solar radiation steadily streams from the sun without interruption and is expected to do so for the next 6 billion years.
The sun is an unsustainable resource because solar radiation steadily streams from the sun now, but it will only do so for the next thousand years.
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.
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.

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.

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.
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.

If the sequence of one strand on DNA is CTA GCT CCA, what is the
complementary strand? *
Answer:
If the sequence of one strand on DNA is CTA GCT CCA, the complementary strand is GAT CGA GGT.
Explanation:
The DNA molecule has four nitrogenous bases in its structure, two purines —adenine and guanine— and two pyrimidines, cytosine and thymine.
The two DNA strands are linked by hydrogen bonds established between their complementary nitrogenous bases, where a purine is complemented by a pyrimidine.
In the case of DNA, adenine is complemented by thymine and cytosine is complemented by guanine:
A=T
C≡G
In the sequence belonging to a DNA strand CTA GCT CCA, the strand that is complementary would be GAT CGA GGT.
