Input: Read this: The Paleozoic spanned from roughly 541 to 252 million years ago (Ma) and is subdivided into six geologic periods; from oldest to youngest they are the Cambrian, Ordovician, Silurian, Devonian, Carboniferous and Permian.

Toward the end of the era the continents gathered together into a supercontinent called Pangaea, which included most of the Earth's land area.

Jehovah's Witnesses refuse blood transfusions, which they consider a violation of God's law based on their interpretation of Acts 15:28, 29 and other scriptures. Since 1961 the willing acceptance of a blood transfusion by an unrepentant member has been grounds for expulsion from the religion. Members are directed to refuse blood transfusions, even in "a life-or-death situation". Jehovah's Witnesses accept non-blood alternatives and other medical procedures in lieu of blood transfusions, and their literature provides information about non-blood medical procedures.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What do Jehovah Witnesses accept in lieu of blood transfusions?
Ah, so.. non-blood alternatives


Question: The American bison is a large bovid which inhabited much of western North America prior to the 1800s, living on the prairies in large herds. However, the vast herds of bison attracted market hunters, who killed dozens of bison for their hides only, leaving the rest to rot. Thousands of these hunters quickly eliminated the bison herds, bringing the population from several million in the early 1800s to a few hundred by the 1880s. Conservation efforts have allowed the population to increase, but the bison remains near-threatened.
Try to answer this question if possible: What type of creature is the American bison?
Answer: a large bovid
