Here are the answers to your questions:
**Question 1**: A freshwater paramecium is placed in salt water. Which of the following events would most likely occur?
- **Answer**: **a** shriveling of the cell
Water from the paramecium would move out into the salt water (which is a hypertonic solution), causing the cell to shrivel.
---
**Question 2**: Crystals of dye, when placed in a beaker of water, eventually spread evenly throughout the water. This is an example of:
- **Answer**: **c** diffusion.
The dye molecules move from an area of higher concentration to an area of lower concentration until evenly distributed.
---
**Question 3**: Which of the following is NOT an example of homeostasis?
- **Answer**: **b** As humans age, they become more susceptible to disease and cancer.
This statement describes a change over time rather than a regulatory mechanism that maintains homeostasis.
---
**Question 4**: Which of the following pairs of structures are analogous?
- **Answer**: **b** insect wing and bird wing.
Both serve a similar function (flight) but do not share a common evolutionary origin.
---
**Question 5**: Some species of snakes have leg bones before birth but lose them before they are born. What is the name for this type of evidence of evolution?
- **Answer**: **c** embryologic.
This refers to the study of embryos in different species showing similarities and differences that can indicate evolutionary relationships.
---
**Question 6**: Which of the following is an assumption that can be made about two species with comparable embryological development?
- **Answer**: **d** They are closely related and are thought to share a similar evolutionary history.
Similar embryological development often indicates a closer evolutionary relationship.
---
**Question 7**: What reproductive barrier appears to keep bullfrogs from mating with leopard frogs?
- **Answer**: **b** breeding season.
Different mating seasons can prevent the two species from mating.
---
**Question 8**: For a polygenic trait, the two extremes were selected for - therefore changing the allelic frequency in a population and the distribution of phenotypes. This is an example of _____.
- **Answer**: **b** disruptive selection.
Disruptive selection favors the extremes of a trait distribution.
---
**Question 9**: The graphs show two types of natural selection. Which statement correctly describes the types of selection represented in the two graphs?
- **Answer**: **b** Stabilizing selection is represented in Graph A, and disruptive selection is represented in Graph B.
(Assuming a typical graph structure where A shows a more central peak and B shows two peaks at extremes.)
---
**Question 10**: Vaccination is a process to help the immune system recognize foreign antigens in the body. Which type of immunity does it affect?
- **Answer**: **a** acquired immunity.
Vaccination helps develop acquired immunity through the recognition of specific antigens.
