Answer the following question given this paragraph: The patterns of atoms that make a mineral affect its physical properties. A mineral's crystal shape is determined by the way the atoms are arranged. For example, you can see how atoms are arranged in halite in Figure above . You can see how salt crystals look under a microscope in Figure below . Salt crystals are all cubes whether they're small or large. Q: A mineral's crystal shape is determined by the way what objects are arranged? Choices: - molecules - particles - Electrons - atoms A:
atoms
Answer the following question given this paragraph: A solution forms when a solute dissolves in a solvent. The rate of dissolving is faster with stirring, a higher temperature, or greater surface area. Many solutes are soluble in water because water is polar. Q: What forms when a solute dissolves in a solvent? Choices: - chemical - gas - liquid - solution A:
solution
Q: Answer the following question given this paragraph: Subphylum Chelicerata includes animals such as spiders, scorpions, horseshoe crabs, and sea spiders. This subphylum is [4] predominantly terrestrial, although some marine species also exist. An estimated 103,000 described species are included in subphylum Chelicerata. The body of chelicerates may be divided into two parts and a distinct "head" is not always discernible. The phylum derives its name from the first pair of appendages: the chelicerae (Figure 15.23a), which are specialized mouthparts. The chelicerae are mostly used for feeding, but in spiders, they are typically modified to inject venom into their prey (Figure 15.23b). As in other members of Arthropoda, chelicerates also utilize an open circulatory system, with a tube-like heart that pumps blood into the large hemocoel that bathes the internal organs. Aquatic chelicerates utilize gill respiration, whereas terrestrial species use either tracheae or book lungs for gaseous exchange. Q: Chelicerata are know for their first pair of appendages, also know as what? Choices: - ambers - chelicides - maxillae - chelicerae A:
A: chelicerae
Question: Answer the following question given this paragraph: Fission is the opposite of fusion and releases energy only when heavy nuclei are split. As noted in Fusion, energy is released if the products of a nuclear reaction have a greater binding energy per nucleon ( BE / A ) than the parent nuclei. Figure 32.25. Q: What process is the opposite of fusion and releases energy only when heavy nuclei are split? Choices: - activation - osmosis - diffusion - fission A:
Answer: fission

Answer the following question given this paragraph: The stars that make up a constellation appear close to each other from Earth. In reality, they may be very distant from one another. Constellations were important to people, like the Ancient Greeks. People who spent a lot of time outdoors at night, like shepherds, named the constellations. They told stories about them. Pictured below is one of the most easily recognized constellations ( Figure below ). The ancient Greeks thought this group of stars looked like a hunter. They named it Orion, after a great hunter in Greek mythology. Q: What do you call the patterns and groups of stars in the sky that ancient people observed and made stories about? Choices: - planets - meteors - asteroid fields - constellations A:
**Answer**
constellations

Answer the following question given this paragraph: Some mutations have a positive effect on the organism in which they occur. They are called beneficial mutations. They lead to new versions of proteins that help organisms adapt to changes in their environment. Beneficial mutations are essential for evolution to occur. They increase an organism's changes of surviving or reproducing, so they are likely to become more common over time. There are several well-known examples of beneficial mutations. Here are just two:. Q: Some mutations lead to new versions of proteins that help organisms adapt to changes in their environment and are essential for evolution to occur. what are these mutations known as? Choices: - superficial mutations - evolutionary mutations - provisional mutations - beneficial mutations A:
(A).
beneficial mutations
