Answer the following question given this paragraph: Monocots Plants in the monocot group are primarily identified as such by the presence of a single cotyledon in the seedling. Other anatomical features shared by monocots include veins that run parallel to the length of the leaves, and flower parts that are arranged in a three- or six-fold symmetry. True woody tissue is rarely found in monocots. In palm trees, vascular and parenchyma tissues produced by the primary and secondary thickening meristems form the trunk. The pollen from the first angiosperms was monosulcate, containing a single furrow or pore through the outer layer. This feature is still seen in the modern monocots. Vascular tissue of the stem is not arranged in any particular pattern. The root system is mostly adventitious and unusually positioned, with no major tap root. The monocots include familiar plants such as the true lilies (which are at the origin of their alternate name of Liliopsida), orchids, grasses, and palms. Many important crops are monocots, such as rice and other cereals, corn, sugar cane, and tropical fruits like bananas and pineapples (Figure 26.17). Q: What is the type of plant that has a single cotelydon in the seedling? Choices: - dicot - conifer - moss - monocot A:
monocot

Answer the following question given this paragraph: However, despite this secrecy several contributions were made to modern-day chemistry. Early acids and bases were discovered, and glassware for running chemical reactions was developed. Alchemy helped improve the study of metallurgy and the extraction of metals from ores. More systematic approaches to research were being developed, although the idea of orderly scientific experimentation was not yet well-established. The groundwork was being laid for the development of chemistry as a foundational science. Q: What was the early study of chemistry called? Choices: - magic systems - horticulture - pharmacology - alchemy A:
**Answer**
alchemy
Q: Answer the following question given this paragraph: 0 .033 g 1 .117 g 100 = 3 .0% When a series of measurements is precise but not accurate, the error is usually systematic. Systematic errors can be caused by faulty instrumentation or faulty technique. The difference between accuracy and precision is demonstrated in Skill Builder ES7. Q: When a series of measurements is precise but not what, the error is usually systematic? Choices: - velocity - length - color - accurate A:
A: accurate
