What is the goal of artificial selection?

If false, explain briefly. We choose the linear model that passes through the most data points on the scatterplot.

Determine if the statement below were true or false:

Sensitivity analysis may be useful in decision analysis since prior probabilities may be inaccurate.

Consider the following linear programming problem:

Maximize $4 X+10 Y$

Subject to: $3 X+4 Y \leq 480$

$\hspace{1.5cm}$ $4 X+2 Y \leq 360$

$\hspace{1.5cm}$ $X, Y \geq 0$

The feasible corner points are $(48,84),(0,120),(0,0)$, and $(90,0)$. What is the maximum possible value for the objective function?

a) $1,032$

b) $1,200$

c) 360

d) $1,600$

e) 840

What characteristics of the Galapagos Islands were particularly important for Darwin?

How has genetic drift affected the world's populations of cheetahs?

How can evolutionary theory explain why Australia is home to relatively few native placental mammals?

Tell how the forelimbs of a bat, a whale, a cat, and a human contribute evidence to support the hypothesis that these mammals evolved from a common ancestor.

True or false: To determine blood type, Luminol is added to blood.

To determine one’s blood type, what is added to the slide? a) blood and antibodies b) only the antibodies c) luminol d) none of the above

How do Lyell's ideas about geology and evidence from the fossil record reinforce each other as ideas about the age of Earth?

Describe how the ideas of Lamarck and Darwin are similar and how they differ.

Analyzing Data: A population containing striped and unstriped snails has recently moved into a new region. Birds break the snails open by dropping them onto rocks. The birds eat the bodies of the snails and leave the shells. In one area, researchers counted both live snails and broken shells. The data are summarized below.

a.Based on the data, tell which form of snail (striped or unstriped) is more likely to be caught by the birds for food. Explain.
b. Suggest a hypothesis to explain what is happening to the snails.
c. Predict how the frequencies of striped and unstriped individuals in the population might change over the generations.
