Answer the following question given this paragraph: The organs of the digestive system are lined with muscles. The muscles contract, or tighten, to push food through the system ( Figure below ). The muscles contract in waves. The waves pass through the digestive system like waves through a slinky. This movement of muscle contractions is called peristalsis . Without peristalsis, food would not be able to move through the digestive system. Peristalsis is an involuntary process, which means that it occurs without your conscious control. Q: What is the movement of muscle in the digestive system called? Choices: - acid reflux - labor contractions - apoptosis - peristalsis A:
peristalsis

Answer the following question given this paragraph: The Levels of Classification Taxonomy (which literally means "arrangement law") is the science of naming and grouping species to construct an internationally shared classification system. The taxonomic classification system (also called the Linnaean system after its inventor, Carl Linnaeus, a Swedish naturalist) uses a hierarchical model. A hierarchical system has levels and each group at one of the levels includes groups at the next lowest level, so that at the lowest level each member belongs to a series of nested groups. An analogy is the nested series of directories on the main disk drive of a computer. For example, in the most inclusive grouping, scientists divide organisms into three domains: Bacteria, Archaea, and Eukarya. Within each domain is a second level called a kingdom. Each domain contains several kingdoms. Within kingdoms, the subsequent categories of increasing specificity are: phylum, class, order, family, genus, and species. As an example, the classification levels for the domestic dog are shown in Figure 12.3. The group at each level is called a taxon (plural: taxa). In other words, for the dog, Carnivora is the taxon at the order level, Canidae is the taxon at the family level, and so forth. Organisms also have a common name that people typically use, such as domestic dog, or wolf. Each taxon name is capitalized except for species, and the genus and species names are italicized. Scientists refer to an organism by its genus and species names together, commonly called a scientific name, or Latin name. This two-name system is called binomial nomenclature. The scientific name of the wolf is therefore Canis lupus. Recent study of the DNA of domestic. Q: Who invented the taxonomic classification system? Choices: - Pascal - gregor mendel - Isaac Newton - carl linnaeus A:
(Answer)
carl linnaeus
Ques: Answer the following question given this paragraph: The strength of acids is measured on the pH scale. A pH value less than 7 indicates an acid, and the lower the number is, the stronger the acid. Q: The strength of acids is measured on what scale? Choices: - Killalot - qcd - g - ph A:
Ans: ph

Ques:Answer the following question given this paragraph: Animal-like protists are called protozoa. Most consist a single cell. Q: What is the term for animal-like protists that are usually single-celled? Choices: - eukaryotes - vertebrates - larvae - protozoa A:

Ans:protozoa
Answer the following question given this paragraph: The rise in greenhouse gases due to human actions is too much of a good thing. It increases the greenhouse effect and causes Earth's average temperature to rise. Rising global temperatures, in turn, are melting polar ice caps and glaciers. Figure below shows how much smaller the Arctic ice cap was in 2012 than it was in 1984. With more liquid water on Earth's surface, sea levels are rising. Q: The rise in greenhouse gases has what effect on the temperature of earth? Choices: - no effect - more moderate - it drops - it increases A:
it increases
