Q: Answer the following question given this paragraph: Evolution that occurs over a short period of time is known as microevolution . It might take place in just a couple of generations. This scale of evolution occurs at the level of the population. The Grants observed evolution at this scale in populations of Darwin's finches. Beak size in finch populations changed in just two years because of a serious drought. Q: Evolution that occurs over a short period of time is known as what? Choices: - short term evolution - pseudoevolution - relatedness - microevolution A:
A: microevolution

Q: What kind of summers do humid continental climates have? Choices: - dry summers - warm summers - wet summers - cold summers A:

Q: Answer the following question given this paragraph: Eukaryotic cells have many specific functions, so it can be said that a cell is like a factory. A factory has many machines and people, and each has a specific role. Just like a factory, the cell is made up of many different parts. Each part has a special role. The different parts of the cell are called organelles , which means "small organs. " All organelles are found in eukaryotic cells. Prokaryotic cells are "simpler" than eukaryotic cells. Though prokaryotic cells still have many functions, they are not as specialized as eukaryotic cells, lacking membrane-bound organelles. Thus, most organelles are not found in prokaryotic cells. Q: In which type of cells are most organelles not found? Choices: - endoplasmic cells - eukaryotic cells - heterogeneous cells - prokaryotic cells A:
A: prokaryotic cells

Elements with magic numbers of protons tend to have more stable isotopes than elements that do not. Q: Elements with magic numbers of what tend to have more stable isotopes? Choices: - nucleus - pressure - molecules - protons A:
A: protons
