Scientists use weather tools to figure out if there is a big storm/tornado/hurricane so they can warn the people to prepare for whatever is coming
Answer:
B.Active transport, because energy is being used to move molecules against the concentration gradient
Explanation:
Substances move in and out of living cells through various transport means. Some substances move passively (without energy) while others move actively (with energy). Active transport of substances involves the movement of molecules against the concentration gradient.
Active transport moves against concentration gradient in the sense that the movement occurs from a region which is less concentrated to one which is more concentrated, hence, energy input in form of ATP is required for such transport to occur. This is the case of the cellular transport in the diagram. Therefore, it is an ACTIVE TRANSPORT because energy input (ATP) is required.
Note, Osmosis and facilitated diffusion are types of passive transport that requires no energy to occur.

An Overview of Geothermal Pros and Cons:
Pros Cons
This energy source is more environmentally friendly than conventional fuel sources. The largest single disadvantage of geothermal energy is that it is location specific.
A source of renewable energy. Gases are released into the atmosphere during digging.
The number of exploitable geothermal resources will increase with ongoing research and development in the industry. Geothermal energy runs the risk of triggering earthquakes.
A sustainable source of energy as its always available unlike wind and solar. Expensive resource to tap into, with high upfront costs ranging from around $2-$7 million for a plant with a 1 megawatt capacity.
A reliable source as its easier to predict the power output from a geothermal plant with a high degree of accuracy. Energy fluid needs to be pumped back into the underground reservoirs faster than it is depleted. Management is required to maintain sustainability.
No fuel is required.
Increase in exploration meaning that new technologies are being created to improve the energy process.
Pollution levels are much lower compared to fossil fuels.

Answer:
Population density of horse
Explanation:
Population density refers to the number of people (or any other living species) existing in a particular area. This reflects the quantity of a particular type of living species that exist over an area of about 1 km².
Population density is obtained mathematically by, dividing the total population of the area by the total size of the area.
In the given question, it describes the quantity (number) of wild horses that are present per square kilometer in the prairie lands. This refers to the population density of horses.
