Q: Evolution that occurs over a short period of time is known as what? Read this paragraph and choose the correct option from the provided answers: 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. Choices: - short term evolution - pseudoevolution - relatedness - microevolution A:
**Answer**
microevolution

Q: What do you get by multiplying volume by the density of water? Read this paragraph and choose the correct option from the provided answers: Consider a gigantic tub filled with water as shown below. A column of water with a cross-sectional area of 1.00 m 2 is designated. If we multiply the cross-sectional area by the height of the column, we get the volume of water in this column. We can then multiply this volume by the density of water, 1000. kg/m 3 , and get the mass of water in the column. We then multiply this mass by the acceleration due to gravity, , to get the weight of the water in this column. Choices: - velocity of water - temperature of water - weight of water - mass of water A:
**Answer**
mass of water
