Answer the following question given this paragraph: You can see how Mendeleev organized the elements in the Figure below . From left to right across each row, elements are arranged by increasing atomic mass. Mendeleev discovered that if he placed eight elements in each row and then continued on to the next row, the columns of the table would contain elements with similar properties. He called the columns groups . They are sometimes called families, because elements within a group are similar but not identical to one another, like people in a family. Q: Mendeleev organized what basic units into rows and columns? Choices: - solutions - compounds - animals - elements A:
elements
Answer the following question given this paragraph: Almost all fungi have a single common ancestor. The earliest fungi may have evolved about 600 million years ago. Fungi colonized land at least 460 million years ago. By 250 million years ago, they may have been the dominant life forms on Earth. Q: Evolving from a single common ancestor, what group of organisms was perhaps the dominant life form on earth 250 million years ago? Choices: - acids - atoms - proteins - fungi A:
fungi
Q: Answer the following question given this paragraph: We saw that the amount of solar radiation an area receives depends on its latitude. The amount of solar radiation affects the temperature of a region. Latitude has other effects on climate. Q: Latitude affects the amount of what received by an area, which in turn affects the temperature of a region? Choices: - chemical radiation - geothermal radiation - current radiation - solar radiation A:
A: solar radiation
Question: Answer the following question given this paragraph: Q: What is the process by which plants and animals increase in size? Choices: - reproduction - grafting - splicing - growth A:
Answer: growth

Answer the following question given this paragraph: The vascular tissues for which these plants are named are specialized to transport fluid. They consist of long, narrow cells arranged end-to-end, forming tubes. There are two different types of vascular tissues, called xylem and phloem. Both are shown in Figure below . Q: What are the two different types of vascular tissues called? Choices: - acid and base - biotic and abiotic - epidermis and dermis - xylem and phloem A:
**Answer**
xylem and phloem
Answer the following question given this paragraph: the bottom of the cell. In roots, a high concentration of IAA inhibits cell elongation. The effect slows growth on the lower side of the root, while cells develop normally on the upper side. IAA has the opposite effect in shoots, where a higher concentration at the lower side of the shoot stimulates cell expansion, causing the shoot to grow up. After the shoot or root begin to grow vertically, the amyloplasts return to their normal position. Other hypothesesinvolving the entire cell in the gravitropism effecthave been proposed to explain why some mutants that lack amyloplasts may still exhibit a weak gravitropic response. Q: In plants, a high concentration of iaa inhibits what? Choices: - Cell reproduction - same elongation - technology elongation - cell elongation A:
cell elongation
