Read this paragraph and choose the correct option from the provided answers: Partial lunar eclipses occur at least twice a year, but total lunar eclipses are less common. The Moon glows with a dull red coloring during a total lunar eclipse ( Figure below ). Choices: - six - 11 - five - two A:

photosynthesis

Q: Q: Class bivalvia ("two shells") includes clams, oysters, mussels, scallops, and these? Read this paragraph and choose the correct option from the provided answers: Class Bivalvia ("two shells") includes clams, oysters, mussels, scallops, and geoducks. Members of this class are found in marine as well as freshwater habitats. As the name suggests, bivalves are enclosed in a pair of shells (valves are commonly called "shells") that are hinged at the dorsal end by shell ligaments as well as shell teeth (Figure 28.22). The overall morphology is laterally flattened, and the head region is poorly developed. Eyespots and statocysts may be absent in some species. Since these animals are suspension feeders, a radula is absent in this class of mollusks. Respiration is facilitated by a pair of ctenidia, whereas excretion and osmoregulation are brought about by a pair of nephridia. Bivalves often possess a large mantle cavity. In some species, the posterior edges of the mantle may fuse to form two siphons that serve to take in and exude water. Choices: - grendels - crabs - octopuss - geoducks A:
A: geoducks

Question: Q: Defined as a difference in electric potential energy, a source of what is required in order to produce an electrical current? Read this paragraph and choose the correct option from the provided answers: Current requires a source of voltage, which is a difference in electric potential energy. Sources of voltage include chemical cells and solar cells. Choices: - wattage - momentum - magnetism - voltage A:
Answer: voltage

Q: In what year was the hardy-weinberg theorem formulated? Read this paragraph and choose the correct option from the provided answers: Evolution occurs in a population when allele frequencies change over time. What causes allele frequencies to change? That question was answered by Godfrey Hardy and Wilhelm Weinberg in 1908 (see the Hardy-Weinberg Theorem concept). Choices: - 1938 - 1901 - 1928 - 1908 A:
**Answer**
1908

Q: How is carbon dioxide and water vapor that is produced by cellular respiration released? Read this paragraph and choose the correct option from the provided answers: A: Breathing consists of inhaling and exhaling, and its purpose is to move gases into and out of the body. Oxygen needed for cellular respiration is brought into the body with each inhalation. Carbon dioxide and water vapor produced by cellular respiration are released from the body with each exhalation. Choices: - peroxidation - fermentation - evaporation - exhalation A:
exhalation
