Answer the following question given this paragraph: When waves of two different frequencies interfere, a phenomenon known as beating occurs. The frequency of a beat is the difference of the two frequencies. Q: When waves of two different frequencies interfere, what phenomenon occurs? Choices: - making - opening - soaking - beating A:
beating
Answer the following question given this paragraph: Sperm are released into the surrounding water through the osculum. If they enter a female sponge through a pore, they may be trapped by collar cells. Trapped sperm are delivered to eggs inside the female body, where fertilization takes place. The resulting zygote develops into a larva. Unlike the adult, the larva is motile. It is covered with cilia that propel it through the water. As the larva grows, it becomes more similar to an adult sponge and loses its ability to swim. Q: Unlike an adult sponge, what stage is motile due to cilia that propel it through water? Choices: - parasite - zygote - pupa - larva A:
larva
Q: Answer the following question given this paragraph: Inside of the nucleus, you will find the chromosomes . Chromosomes are strands of DNA wrapped around proteins. They contain genes , or small units of genetic material (DNA) that contains the code for the creation of a protein. Human cells have 46 chromosomes (23 pairs). There are hundreds to thousands of genes on each chromosome. Q: What do you call the strands of dna wrapped around proteins, which are located inside the nucleus? Choices: - receptors - ribosomes - fibrils - chromosomes A:
A: chromosomes
Question: Answer the following question given this paragraph: There are no forces of attraction or repulsion between gas particles . Attractive forces are responsible for particles of a real gas condensing together to form a liquid. It is assumed that the particles of an ideal gas have no such attractive forces. The motion of each particle is completely independent of the motion of all other particles. Q: Which measure indicates the number of electrons in a given sublevel? Choices: - subscripts - mole - coefficients - superscripts A:
Answer: superscripts

Answer the following question given this paragraph: 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. Q: Class bivalvia ("two shells") includes clams, oysters, mussels, scallops, and these? Choices: - grendels - crabs - octopuss - geoducks A:
**Answer**
geoducks
