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? Choices: - cluster - tuck - spasm - clade A:
clade
Answer the following question given this paragraph: Recall that air pollution is due to chemical substances and particles released into the air mainly by human actions. When most people think of air pollution, they think of the pollution outdoors. But it is just as easy to have indoor air pollution. Your home or school classroom probably doesn't get much fresh air. Sealing up your home reduces heating and cooling costs. But this also causes air pollution to stay trapped indoors. And people today usually spend a majority of their time indoors. So exposure to indoor air pollution can become a significant health risk. Q: What is caused by human actions that releases chemical substances and particles into the air? Choices: - CFO pollution - Improper Emissions - heavy pollution - air pollution A:
air pollution
Q: Answer the following question given this paragraph: Magma at the mid-ocean ridge creates new seafloor. Q: What creates a new seafloor at the mid-ocean ridge? Choices: - earthquake - hurricane - glaciers - magma A:
A: magma
Question: Answer the following question given this paragraph: Q: What parts of the cell does cell differentiation involve changes in? Choices: - cystine and cell wall - endoderm and epidermis - cell membrane and nucleus - cytoplasm and cell wall A:
Answer: cytoplasm and cell wall

Answer the following question given this paragraph: Chapter 38 1 Figure 38.19B 3 Figure 38.38 In the presence of Sarin, acetycholine is not removed from the synapse, resulting in continuous stimulation of the muscle plasma membrane. At first, muscle activity is intense and uncontrolled, but the ion gradients dissipate, so electrical signals in the T-tubules are no longer possible. The result is paralysis, leading to death by asphyxiation. 4 A 6 D 8 B 10 A 12 B 14 C 16 D 18 D 20 The female pelvis is tilted forward and is wider, lighter, and shallower than the male pelvis. It is also has a pubic angle that is broader than the male pelvis. 22 Compact bone tissue forms the hard external layer of all bones and consists of osteons. Compact bone tissue is prominent in areas of bone at which stresses are applied in only a few directions. Spongy bone tissue forms the inner layer of all bones and consists of trabeculae. Spongy bone is prominent in areas of bones that are not heavily stressed or at which stresses arrive from many directions. 24 The hip joint is flexed and the knees are extended. 26 Because ATP is required for myosin to release from actin, muscles would remain rigidly contracted until more ATP was available for the myosin cross-bridge release. This is why dead vertebrates undergo rigor mortis. 28 Neurons will not be able to release neurotransmitter without calcium. Skeletal muscles have calcium stored and don't need any from the outside. Q: What kind of tissue consists of trabeculae and forms the inner layer of all bones? Choices: - flotsam bone tissue - denser bone tissue - corregated bone tissue - spongy bone tissue A:
**Answer**
spongy bone tissue
Q: Answer the following question given this paragraph: Chemical reactions that consume energy are called endothermic reactions . Energy is usually absorbed from the surroundings as heat. An example is the synthesis of ammonia, described above. In organisms, endothermic reactions are called anabolic reactions . Anabolic reactions construct molecules from smaller units. An example is the synthesis of proteins from amino acids. Endothermic reactions can be represented by the general chemical equation:. Q: Chemical reactions that consume energy are called what? Choices: - exothermic reactions - inefficient reactions - greedy reactions - endothermic reactions A:
A: endothermic reactions
