Answer the following question given this paragraph: There are a variety of types of movable joints, which are illustrated in Figure below . The joints are classified by how they move. For example, a ball-and-socket joint, such as the shoulder, has the greatest range of motion, allowing movement in several directions. Other movable joints, including hinge joints such as the knee, allow less movement. Q: What type of joint has the greatest range of motion? Choices: - Hinge - Gliding - Pivot - ball-and-socket A:
ball-and-socket

Answer the following question given this paragraph: Plants don't have an immune system, but they do respond to disease. Typically, their first line of defense is the death of cells surrounding infected tissue. This prevents the infection from spreading. Q: Because plants lack what kind of system, their first line of defense is usually the death of cells surrounding infected tissue to prevent spread of infection? Choices: - nervous system - digestion system - hormones system - immune system A:
(Answer)
immune system
Ques: Answer the following question given this paragraph: Carl Woese and the Phylogenetic Tree In the past, biologists grouped living organisms into five kingdoms: animals, plants, fungi, protists, and bacteria. The organizational scheme was based mainly on physical features, as opposed to physiology, biochemistry, or molecular biology, all of which are used by modern systematics. The pioneering work of American microbiologist Carl Woese in the early 1970s has shown, however, that life on Earth has evolved along three lineages, now called domainsBacteria, Archaea, and Eukarya. The first two are prokaryotic cells with microbes that lack membrane-enclosed nuclei and organelles. The third domain contains the eukaryotes and includes unicellular microorganisms together with the four original kingdoms (excluding bacteria). Woese defined Archaea as a new domain, and this resulted in a new taxonomic tree (Figure 1.17). Many organisms belonging to the Archaea domain live under extreme conditions and are called extremophiles. To construct his tree, Woese used genetic relationships rather than similarities based on morphology (shape). Woese's tree was constructed from comparative sequencing of the genes that are universally distributed, present in every organism, and conserved (meaning that these genes have remained essentially unchanged throughout evolution). Woese's approach was revolutionary because comparisons of physical features are insufficient to differentiate between the prokaryotes that appear fairly similar in spite of their tremendous biochemical diversity and genetic variability (Figure 1.18). The comparison of homologous DNA and RNA sequences provided Woese with a sensitive device that revealed the extensive variability of prokaryotes, and which justified the separation of the prokaryotes into two domains: bacteria and archaea. Q: In the past, biologists grouped living organisms into five kingdoms: animals, plants, fungi, protists, and what? Choices: - trees - pathogens - lizards - bacteria A:
Ans: bacteria
(Q).
Answer the following question given this paragraph: Q: In multicellular organisms, only mutations in cell lines that produce gametes can be passed to what? Choices: - cells - clones - proteins - offspring A:
(A).
offspring
Ques:Answer the following question given this paragraph: In a hydrogen replacement reaction, the hydrogen in the acid is replaced by an active metal. Q: In a hydrogen replacement reaction, the hydrogen in the acid is replaced by what? Choices: - gas - water - oxygen - an active metal A:

Ans:an active metal
Ques: Answer the following question given this paragraph: Concentration is the number of particles of a substance in a given volume. When the concentration of reactants is higher, the reaction rate is faster. At higher concentrations, particles of reactants are crowded closer together, so they are more likely to collide and react. Did you ever see a sign like the one in the Figure below ? You might see it where someone is using a tank of pure oxygen for a breathing problem. Combustion, or burning, is a chemical reaction in which oxygen is a reactant. A greater concentration of oxygen in the air makes combustion more rapid if a fire starts burning. Q: What kind of reaction do you see when the concentration of reactants is higher? Choices: - regular reaction rate - slow reaction rate - constant reaction rate - faster reaction rate A:
Ans:
faster reaction rate
