True or false. Nonmagnetic Rare Earth Metal Samarium can be used to repel sharks.
Answer:
false
Explanation:
Answer: i think false
Explanation:
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.

Which best describes two counteracting forces on an object?
using a dolly to push a box to another location
two children pulling apart a wishbone
a group of dogs pulling a dogsled across ice
two people pushing a broken-down car up the road
Answer: B) two children pulling apart a wishbone
One person is on the left side, and the other person is on the right side. They pull in opposite directions to separate the bone. These forces counteract each other since they go in opposite directions.
In contrast, each of choice A, C, and D describe one or more forces that work together to go in the same direction. This could be a pulling force, or a pushing force, it doesn't matter either way. We can rule out choices A,C, and D for this reason.
