Use at least three complete sentences to explain how global wind patterns such as the prevailing westerlies in the northern hemisphere would be impacted if the rotation of Earth stops.(5 points)
Answer:
If the Earth did not spin on its axis, the atmosphere would only circulate between the poles and the equator. And if this happens, the very same thing is bound to happen over again. That is, the atmosphere would only circulate in a back-and-forth pattern between the poles and the equator over and over.

What do motor nerve cells do?
A. carry messages from cerebellum to cerebrum
B. carry messages from brain to the organs and tissues in the body
C. carry water to the well
D. send messages to the brain stem
Answer:
Motor neurons of the spinal cord are part of the central nervous system (CNS) and connect to muscles, glands and organs throughout the body. These neurons transmit impulses from the spinal cord to skeletal and smooth muscles (such as those in your stomach), and so directly control all of our muscle movements.

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.
