Pellets are the portions of a bird's diet that have not been digested and are regurgitated. Examples of pellets include hair and bones . Pellets are produced by a wide variety of bird species, including but not limited to birds of prey, crows, and even sparrows.
Owl pellets consist of indigestible elements of their prey, such as bones, fur, claws, and teeth. However, they perform another crucial function for the owl. Regurgitating pellets, which travel through the bird's gullet on the way back up, scrub and clean the digestive tract, eliminating infections and maintaining the bird's health. Those who raise birds of prey like owls and falcons can utilize the pellets to determine the health of their birds.
Prey animals, such as field mice, have learnt to avoid the pellets since they are infectious agents. However, certain owl pellet pathogens, such as Salmonella, can potentially infect humans.

Answer:
What is a difference between prokaryotic and eukaryotic cells?
Prokaryotes lack membrane-bound nucleus while eukaryotes possess membrane-bound nucleus also eukaryotes are well developed which made it to houses several cell organelles compared to prokaryotes which are not fully developed to make up more cell organelles.

Answer:
4.index fossils, intrusions, and cross-cutting relationships
Explanation:
There are various geologic features or phenomenon that determines the relative ages of rocks . This geologic features or events includes index fossils , intrusions, cross cutting relationship etc. Note relative ages of rock does not give the actual ages oft the rocks but instead compares the ages of these rocks. Knowing the relative ages of rocks, one can decipher which rock is older or which one is younger. The geologic features give details on the sequence of event that happens through the formation.
Like the principle of cross cutting relationship states that the geologic feature which cut across or intrudes another geologic feature is younger than it surrounding rock.
Index fossils are remains of organisms that are widely spread. The deposition of this remains can give the sequence for deposition of the surrounding rocks which these fossils are found.
Intrusions occurs when geologic features like plutons invades another rock body. Geologically, the plutons will be younger than the surrounding or host rock.

Image result for An organ system is made up of organisms that have
Humans—and other complex multicellular organisms—have systems of organs that work together, carrying out processes that keep us alive. The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems
