Problem:OPTIONS:
- alternating current
- direct current
- relativity current
- conventional current

Answer the following question given this paragraph: Figure 20.4 Current I is the rate at which charge moves through an area A , such as the cross-section of a wire. Conventional current is defined to move in the direction of the electric field. (a) Positive charges move in the direction of the electric field and the same direction as conventional current. (b) Negative charges move in the direction opposite to the electric field. Conventional current is in the direction opposite to the movement of negative charge. The flow of electrons is sometimes referred to as electronic flow. Q: Positive charges move in the direction of the electric field and the same direction as what current? A:
****
A: conventional current

Answer the following question given this paragraph: Marsupials give birth to a tiny, immature embryo. The embryo then continues to grow and develop in a pouch on the mother's belly. This is less risky for the mother. However, the embryo is fragile, so it may be less likely to survive than the fetus of a placental mammal. Q: What type of mammal gives birth to young that need to develop further in the mother's pouch after birth? A:
OPTIONS:
- humans
- whales
- aborigines
- marsupials
marsupials

Answer the following question given this paragraph: Chemical reactions vary widely in the speeds with which they occur. Some reactions occur very quickly. If a lighted match is brought in contact with lighter fluid or another flammable liquid, it erupts into flame instantly and burns fast. Other reactions occur very slowly. A container of milk in the refrigerator will be good to drink for weeks before it begins to turn sour. Millions of years were required for dead plants under Earth's surface to accumulate and eventually turn into fossil fuels such as coal and oil. Q: Exemplified by a lit match bursting into flame or the process that forms fossil fuels, chemical reactions vary greatly in terms of what? A:
OPTIONS:
- duration
- density
- power
- speed

Answer: speed

Question: Answer the following question given this paragraph: Childhood cancer is rare. The main type of cancer in children is leukemia. It makes up about one third of all childhood cancers. It occurs when the body makes abnormal white blood cells. Q: What is the most common type of cancer developed in children? A:
OPTIONS:
- anemia
- lung cancer
- stomach cancer
- leukemia
Answer: leukemia

output: sporozoites

Problem: OPTIONS:
- deletions

Q: Answer the following question given this paragraph: 16.7 | Cancer and Gene Regulation By the end of this section, you will be able to: Describe how changes to gene expression can cause cancer Explain how changes to gene expression at different levels can disrupt the cell cycle Discuss how understanding regulation of gene expression can lead to better drug design Cancer is not a single disease but includes many different diseases. In cancer cells, mutations modify cell-cycle control and cells don't stop growing as they normally would. Mutations can also alter the growth rate or the progression of the cell through the cell cycle. One example of a gene modification that alters the growth rate is increased phosphorylation of cyclin B, a protein that controls the progression of a cell through the cell cycle and serves as a cell-cycle checkpoint protein. For cells to move through each phase of the cell cycle, the cell must pass through checkpoints. This ensures that the cell has properly completed the step and has not encountered any mutation that will alter its function. Many proteins, including cyclin B, control these checkpoints. The phosphorylation of cyclin B, a post-translational event, alters its function. As a result, cells can progress through the cell cycle unimpeded, even if mutations exist in the cell and its growth should be terminated. This post-translational change of cyclin B prevents it from controlling the cell cycle and contributes to the development of cancer. Q: Cancer involves what changes that modify cell-cycle control and alter the growth rate or progression of the cell through the cell cycle? A:
Answer:
mutations
