- variable intermolecular forces
- angular intermolecular forces
- uniform intermolecular forces

Answer the following question given this paragraph: Deformation of the ionic crystal causes one plane of atoms to slide along another. The resulting repulsive interactions between ions with like charges cause the layers to separate. Crystals tend to have relatively sharp, well-defined melting points because all the component atoms, molecules, or ions are the same distance from the same number and type of neighbors; that is, the regularity of the crystalline lattice creates local environments that are the same. Thus the intermolecular forces holding the solid together are uniform, and the same amount of thermal energy is needed to break every interaction simultaneously. Amorphous solids have two characteristic properties. When cleaved or broken, they produce fragments with irregular, often curved surfaces; and they have poorly defined patterns when exposed to x-rays because their components are not arranged in a regular array. An amorphous, translucent solid is called a glass. Almost any substance can solidify. Q: Why do crystals have relatively sharp and well-defined melting points? A:
****
A: uniform intermolecular forces

Answer the following question given this paragraph: the history of galactic evolution has been, and the nature of space in their vicinity. However, so many black holes are now known that correlations between black hole mass and galactic nuclei characteristics are being studied. What is the mechanism for the energy output of quasars? These distant and extraordinarily energetic objects now seem to be early stages of galactic evolution with a supermassive black-hole-devouring material. Connections are now being made with galaxies having energetic cores, and there is evidence consistent with less consuming, supermassive black holes at the center of older galaxies. New instruments are allowing us to see deeper into our own galaxy for evidence of our own massive black hole. Q: What distant and extraordinarily energetic objects now seem to be early stages of galactic evolution with a supermassive black-hole-devouring material? A:
OPTIONS:
- pulsars
- stars
- neutrinos
- quasars
quasars

Answer the following question given this paragraph: Adolescence includes the physical changes of puberty among other changes. Q: Puberty and other physical changes occurs during which stage of development? A:
OPTIONS:
- childhood
- infancy
- adulthood
- adolescence

Answer: adolescence

Question: Answer the following question given this paragraph: Natural Methods of Asexual Reproduction Natural methods of asexual reproduction include strategies that plants have developed to self-propagate. Many plantslike ginger, onion, gladioli, and dahliacontinue to grow from buds that are present on the surface of the stem. In some plants, such as the sweet potato, adventitious roots or runners can give rise to new plants Figure 32.25. In Bryophyllum and kalanchoe, the leaves have small buds on their margins. When these are detached from the plant, they grow into independent plants; or, they may start growing into independent plants if the leaf touches the soil. Some plants can be propagated through cuttings alone. Q: Natural methods of asexual reproduction, such as cuttings or budding, include strategies that plants have developed to perform what? A:
OPTIONS:
- multi-propagation
- mono-propagation
- iso-propagation
- self-propagation
Answer: self-propagation

input with options: Answer the following question given this paragraph: One way of classifying organisms that shows phylogeny is by using the clade. A clade is a group of organisms that includes an ancestor and all of its descendants. Clades are based on cladistics. This is a method of comparing traits in related species to determine ancestor-descendant relationships. Clades are represented by cladograms, like the one in Figure below . This cladogram represents the mammal and reptile clades. The reptile clade includes birds. It shows that birds evolved from reptiles. Linnaeus classified mammals, reptiles, and birds in separate classes. This masks their evolutionary relationships. Q: What is one way of classifying organisms called? A:
OPTIONS:
- cluster
- tuck
- spasm
- clade
output: clade

Problem: OPTIONS:
- deep sea diversions
- deep sea caves
- deep sea resonances
- deep sea trenches
Q: Answer the following question given this paragraph: Deep sea trenches are found near chains of active volcanoes. These volcanoes can be at the edges of continents or in the oceans. Trenches are the deepest places on Earth. The deepest trench is the Mariana Trench in the southwestern Pacific Ocean. This trench plunges about 11 kilometers (35,840 feet) beneath sea level. The ocean floor does have lots of flat areas. These abyssal plains are like the scientists had predicted. Q: What are the deepest places on earth? A:
Answer:
deep sea trenches
