What is weather forecasting?Weather forecasting is the application of science and technology to predict atmospheric conditions at a particular place and time.People have been trying to predict the weather informally for thousands of years, but have been doing so formally since the 19th century.Weather forecasting is the application of science and technology to predict atmospheric conditions for a particular place and time.Humans have tried to predict the weather informally for thousands of years, but only formally since the 19th century due to incomplete understanding of the ocean, measurement errors in initial conditions, atmosphere and related processes.Weather warnings are important forecasts that protect lives and property.Forecasts based on temperature and precipitation are important for agriculture and therefore for commodity market traders. Temperature forecasts are used by utility companies to forecast demand for the next few days.Many people use the daily weather forecast to decide what to wear on any given day.To learn more about weather forecasting, refer to:

how does energy transfer through a system? Is all the energy conserved?
Answer:
Explanation:
The total change of energy in any system is always equal to the total energy transferred into or out of the system. This is called conservation of energy. ... Energy can also be transferred from place to place by electric currents. Heating is another process for transferring energy.

Owls, hawks, and eagles are types of raptors, animals which have hooked beaks and sharp claws, and are therefore adapted for seizing prey animals. Hawks and eagles differ from owls in that they eat their prey animals by tearing them into small pieces, picking out the flesh, and avoiding most of the fur and bones. They also have strong stomachs that can digest most of the bone material which they might eat. The relatively small amount of indigestible bone and fur that remain will be compacted by their stomach muscles into a pellet similar to the owls. Do you think an eagle pellet would be as useful for dissecting as an owl's? Why or why not? Explain your reasoning.
An eagle pellet wouldn't be as useful for dissection as an owl pellet. The pellet also contains the animal's bones and fur.
What is dissection?Dissection is the dissection of an animal or plant's body to examine the anatomical structure. In pathology along with forensic medicine, autopsy is used to identify the cause of human death. In biology or natural science classrooms under middle school as well as high school, less thorough dissections of plants or smaller animals stored with a formaldehyde solution are often carried out or displayed.
Medical students on medical schools perform in-depth dissections on adult and child cadavers, both fresh and preserved, as part of their instruction in topics including anatomy, pathology, and forensic medicine. As a result, dissection is frequently performed at an anatomy lab or a mortuary. An eagle pellet wouldn't be as useful for dissection as an owl pellet. The pellet also contains the animal's bones and fur.
Therefore, an eagle pellet wouldn't be as useful for dissection as an owl pellet. The pellet also contains the animal's bones and fur.
