Answer the following question given this paragraph: Knowledge gained by this basic research on yeast cells has been applied to practical problems. Scientists have developed drugs to treat cancer based on knowledge of the cell cycle. Cancer is a disease in which cells divide out of control. The new drugs interfere with the cell cycle of cancer cells, so the cells stop dividing. This is an example of applied science. The aim of applied science is to find solutions to practical problems. Applied science generally rests on knowledge gained by basic science. Q: What is the name for the disease in which cells divide out of control? Choices: - diabetes - mutation - angina - cancer A:
cancer
Answer the following question given this paragraph: The epidermis is the outer layer of skin, consisting of epithelial cells and little else (see Figure below ). For example, there are no nerve endings or blood vessels in the epidermis. The innermost cells of the epidermis are continuously dividing through mitosis to form new cells. The newly formed cells move up through the epidermis toward the skin surface, while producing a tough, fibrous protein called keratin. The cells become filled with keratin and die by the time they reach the surface, where they form a protective, waterproof layer called the stratum corneum. The dead cells are gradually shed from the surface of the skin and replaced by other cells. Q: What is the outer layer of skin, consisting almost entirely of epithelial cells? Choices: - hypodermis - connective tissue - dermis - epidermis A:
epidermis
Q: Answer the following question given this paragraph: Q: Where a cell resides, how it appears, and what it does define its what? Choices: - minute race - slowing rate - life cycle - development fate A:
A: development fate
Question: Answer the following question given this paragraph: Q: What kind of cell is a cell with two chromosomes? Choices: - haploid cells - mutated cell - neurotic cell - diploid cell A:
Answer: diploid cell

Answer the following question given this paragraph: Pressure and temperature at constant volume are directly proportional. Q: When volume does not change, temperature is proportional to what other property? Choices: - Length - resistance - Density - pressure A:
**Answer**
pressure

Answer the following question given this paragraph: Linnaeus classified organisms based on obvious physical traits. Basically, organisms were grouped together if they looked alike. After Darwin published his theory of evolution in the 1800s (discussed in the following chapter), scientists looked for a way to classify organisms that showed phylogeny. Phylogeny is the evolutionary history of a group of related organisms. It is represented by a phylogenetic tree , like the one in Figure below . Q: Which scientist was responsible for the theory of evolution by natural selection? Choices: - stephen hawking - galileo Galilei - albert einstein - charles darwin A:
**Answer**
charles darwin
