there's a mistake in the question, weight isn't measured in pounds its measured in newtons, mass is measured in pounds
im going to assume ur asking why our weight is different on the moon and earth, and why the mass remains the same
weight is how many newtons of gravity is acting on you. the gravitational field strength on earth and moon are very different. on earth its 9.8N and on the moon its 1.6N. Because the force of gravity is weaker on the moon, you weigh less.
Answer:
B:The formation of two or more species from a common ancestor.
Explanation:
Answer:
Examples of scientific theories in different areas of science include: Astronomy: Big Bang Theory. Biology: Cell Theory; Theory of Evolution; Germ Theory of Disease. Chemistry: Atomic Theory; Kinetic Theory of Gases.
Answer:
Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved. Fossils provide evidence of long-term evolutionary changes, documenting the past existence of species that are now extinct.
To give one classic example, the forelimbs of whales, humans, and birds look quite different on the outside. That's because they're adapted to function in different environments. However, if you look at the bone structure of the forelimbs, you'll find that the organization of the bones is remarkably similar across species. It's unlikely that such similar structures would have evolved independently in each species, and more likely that the basic layout of bones was already present in a common ancestor of whales, humans, and birds.
