In one species of guinea pig, the gene for black fur is dominant while the gene for
brown fur is recessive. A male guinea pig with black fur and a female guinea pig with
black fur produce a female offspring with black fur. Which of the following BEST
describes why the trait for fur color is transferred from the parents to the offspring?
O Genetic mutations
O Acquired traits that are passed on through mitosis
O Environmental conditions such as the type of cage the owner keeps the guinea pig in
O Genes store hereditary information in the DNA of a cell, that leads to traits passing from one
generation to the next

For the strategies below, decide whether they are best described as demand-side solutions or supply-side solutions to meeting human needs for fresh water. remember that a demand-side solution reduces demand for fresh water, whereas a supply-side solution increases the supply of fresh water. (a) damming a river to create a reservoir (b) desalinating seawater (c) a nation invading a neighboring country to access their rivers (d) raising water prices for consumers and businesses (e) providing tax breaks for companies that use less water (f) replacing inefficient irrigation with more-efficient drip irrigation to grow crops (g) requiring low-flow showerheads in all new homes
