Q: What is it called when bones get longer and bigger? Read this paragraph and choose the correct option from the provided answers: Choices: - expansion - replication - reproduction - growth A:
growth

(Question)
Q: What organism constitutes frothy green "pond scum"? Read this paragraph and choose the correct option from the provided answers: Polluted water can form a frothy green scum on the surface. This "pond scum" is actually a living organism, algae. The algae are plant-like protists. Usually the algae are too small to notice, but sometimes algae grow in excess because of the excess nutrients in polluted water. Choices: - bacteria - sponges - protozoa - algae A:
(Answer)
algae

Ques: Q: What does erosion do to pieces of broken rock? Read this paragraph and choose the correct option from the provided answers: Erosion moves the pieces of broken rock. Choices: - lead them - Smooth them - Cancel Them - moves them A:
Ans: moves them

Q: On the atomic level, the dissolution of an ionic compound occurs when water interacts with the what in the crystal lattice? Read this paragraph and choose the correct option from the provided answers: The last property above requires some additional explanation. We are all familiar with the process of dissolution on a large scale. If you stir a spoonful of salt into a glass of water, the salt crystals are broken down and seem to disappear into the water. On the atomic level, the dissolution of an ionic compound occurs when water interacts with the ions in the crystal lattice, causing the lattice to break apart ( Figure below ):. Choices: - atoms - fractals - particles - ions A:
(A).
ions

Ques:Q: Amphibians are ectothermic vertebrates that divide their time between freshwater and what else? Read this paragraph and choose the correct option from the provided answers: Amphibians are ectothermic vertebrates that divide their time between freshwater and terrestrial habitats. They are the first true tetrapods, or vertebrates with four limbs. Amphibians breathe with gills as larvae and with lungs as adults. They have a three-chambered heart and relatively complex nervous system. Choices: - saltwater - deserts - arboreal habitats - terrestrial habitats A:

Ans:terrestrial habitats

Ques:Q: Gases are most ideal at high temperature and what pressure? Read this paragraph and choose the correct option from the provided answers: Under what conditions then, do gases behave least ideally? When a gas is put under high pressure, its molecules are forced closer together as the empty space between the particles is diminished. A decrease in the empty space means that the assumption that the volume of the particles themselves is negligible is less valid. When a gas is cooled, the decrease in kinetic energy of the particles causes them to slow down. If the particles are moving at slower speeds, the attractive forces between them are more prominent. Another way to view it is that continued cooling the gas will eventually turn it into a liquid and a liquid is certainly not an ideal gas anymore (see liquid nitrogen in the Figure below ). In summary, a real gas deviates most from an ideal gas at low temperatures and high pressures. Gases are most ideal at high temperature and low pressure. Choices: - absolute - high - stable - low A:

Ans:
low
