Q: Answer the following question given this paragraph:   Veins are made primarily of xylem and phloem. They transport water and minerals to the cells of leaves and carry away dissolved sugar.   Q: What are xylem and phloem responsible for transporting to the cells of leaves?   Choices:  - air and dirt  - water and blood  - light and gas  - water and minerals  A:
A: water and minerals


Q: Answer the following question given this paragraph:   When electrons return to a lower energy level, they emit energy in the form of light.   Q: When electrons return to a lower energy level, they emit the excess energy in the form of what?   Choices:  - weight  - electricity  - energy  - light  A:
A: light


Q: Answer the following question given this paragraph:      Q: What are the outpocketings of the digestive tract that remove nitrogenous wastes and function in osmoregulation?   Choices:  - olivary tubules  - integumentary tubules  - intestinal tubules  - malpighian tubules  A:
A: malpighian tubules


Q: Answer the following question given this paragraph:   Paleontology, another branch of biology, uses fossils to study life’s history (Figure 1.20). Zoology and botany are the study of animals and plants, respectively. Biologists can also specialize as biotechnologists, ecologists, or physiologists, to name just a few areas. This is just a small sample of the many fields that biologists can pursue. Biology is the culmination of the achievements of the natural sciences from their inception to today. Excitingly, it is the cradle of emerging sciences, such as the biology of brain activity, genetic engineering of custom organisms, and the biology of evolution that uses the laboratory tools of molecular biology to retrace the earliest stages of life on earth. A scan of news headlines—whether reporting on immunizations, a newly discovered species, sports doping, or a genetically-modified food—demonstrates the way biology is active in and important to our everyday world.   Q: What branch of biology uses fossils to study life’s history?   Choices:  - morphology  - entomology  - gerontology  - paleontology  A:

A: paleontology
