Answer the following question given this paragraph: Most flatworms have a distinct head region that includes nerve cells and sensory organs, such as eyespots. The development of a head region, called cephalization , evolved at the same time as bilateral symmetry in animals. This process does not occur in cnidarians, which evolved prior to flatworms and have radial symmetry. Q: The development of a head region is called what? A:

OPTIONS:
- trichina
- spore
- cocklebur
- cephalization

Answer: cephalization

Problem: OPTIONS:
- tropical
- desert
- taiga
- tundra

Answer the following question given this paragraph: The cerebrum is the largest part of the brain. It controls conscious functions such as reasoning, language, sight, touch, and hearing. It is divided into two hemispheres, or halves. The hemispheres are very similar but not identical to one another. They are connected by a thick bundle of axons deep within the brain. Each hemisphere is further divided into the four lobes shown in Figure below . Q: What is the largest part of the brain? A:
OPTIONS:
- cerebellum
- limbic system
- stem
- cerebrum
cerebrum

Answer the following question given this paragraph: An example of a human polygenic trait is adult height. Several genes, each with more than one allele, contribute to this trait, so there are many possible adult heights. For example, one adult's height might be 1.655 m (5.430 feet), and another adult's height might be 1.656 m (5.433 feet) tall. Adult height ranges from less than 5 feet to more than 6 feet, but the majority of people fall near the middle of the range, as shown in Figure below . Q: Because several genes, each with more than one allele, contribute to determining height in humans, height is considered what kind of trait? A:
OPTIONS:
- adaptive
- maladaptive
- epigenetic
- polygenic

Answer: polygenic

input with options: Answer the following question given this paragraph: Total internal reflection allows the light to travel down the optical fiber and not pass through the sides of the tube. The light continuously reflects from the inside of the tube and eventually comes out the end. Optical fibers make interesting lamps but they are also used to transport telephone and television signals. Q: What kind of fibers are used to transport telephone and television signals? A:
OPTIONS:
- touch fibers
- process fibers
- hair fibers
- optical fibers
output:
optical fibers
