- isotope
- ion

A: ion

input: OPTIONS:
- muscular
- epithelial
- nervous
- connective Now, answer this question: Answer the following question given this paragraph: Blood Blood is considered a connective tissue because it has a matrix, as shown in Figure 33.17. The living cell types are red blood cells (RBC), also called erythrocytes, and white blood cells (WBC), also called leukocytes. The fluid portion of whole blood, its matrix, is commonly called plasma. Q: What type of tissue is blood? A:
A:
output: connective

Answer the following question given this paragraph: Solar cells convert the energy in sunlight to electrical energy. They contain a material such as silicon that absorbs light energy and gives off electrons. Q: What can be used to convert the energy provided by the sun to usable electrical energy? A:

OPTIONS:
- Wind Mills
- Pannels
- Power Plants
- solar cells

Answer: solar cells

Problem: OPTIONS:
- cooling current
- microwave current
- Light Current
- electric current
Q: Answer the following question given this paragraph: The process of generating electric current with a changing magnetic field is called electromagnetic induction . It occurs whenever a magnetic field and an electric conductor, such as a coil of wire, move relative to one another. As long as the conductor is part of a closed circuit, current will flow through it whenever it crosses magnetic field lines. One way this can happen is pictured in Figure below . It shows a magnet moving inside a wire coil. Another way is for the coil to move instead of the magnet. Q: When you change a magnetic field through electromagnetic induction what do you create? A:
Answer: electric current

Problem:OPTIONS:
- cross-breeding
- assimilation
- mutations
- hybridization

Answer the following question given this paragraph: These are plants that always produce offspring that look like the parent. By experimenting with true-breeding pea plants, Mendel avoided the appearance of unexpected traits in offspring that might occur if the plants were not true breeding. The garden pea also grows to maturity within one season, meaning that several generations could be evaluated over a relatively short time. Finally, large quantities of garden peas could be cultivated simultaneously, allowing Mendel to conclude that his results did not come about simply by chance. Mendel performed hybridizations, which involve mating two true-breeding individuals that have different traits. In the pea, which is naturally self-pollinating, this is done by manually transferring pollen from the anther of a mature pea plant of one variety to the stigma of a separate mature pea plant of the second variety. Plants used in first-generation crosses were called P, or parental generation, plants (Figure 8.3). Mendel collected the seeds produced by the P plants that resulted from each cross and grew them the following season. These offspring were called the F1, or the first filial (filial = daughter or son), generation. Once Mendel examined the characteristics in the F1 generation of plants, he allowed them to self-fertilize naturally. He then collected and grew the seeds from the F1 plants to produce the F2, or second filial, generation. Mendel's experiments extended beyond the F2 generation to the F3 generation, F4 generation, and so on, but it was the ratio of characteristics in the P, F1, and F2 generations that were the most intriguing and became the basis of Mendel's postulates. Q: In his work with pea plants, mendel performed what, which involves mating two true-breeding individuals that have different traits? A:
****
A: hybridization

Problem:OPTIONS:
- snow
- Volcanoes
- air
- rocks on ocean floor

Answer the following question given this paragraph: Scientists don't know for certain why magnetic reversals occur, but there is hard evidence that they have for hundreds of millions of years. The evidence comes from rocks on the ocean floor. Look at Figure below . They show the same ridge on the ocean floor during different periods of time. Q: Where does evidence that magnetic reversals occur come from? A:
****
A:
rocks on ocean floor
