Answer the following question given this paragraph: makes it clear that the deformation is proportional to the applied force. Figure 5.13 shows the Hooke's law relationship between the extension L of a spring or of a human bone. For metals or springs, the straight line region in which Hooke's law pertains is much larger. Bones are brittle and the elastic region is small and the fracture abrupt. Eventually a large enough stress to the material will cause it to break or fracture. Tensile strength is the breaking stress that will cause permanent deformation or fracture of a material. Hooke's Law. Q: What term refers to the breaking stress that will cause permanent deformation or fracture of a material? Choices: - elasticity - malleability - viscosity - tensile strength A:
tensile strength

Answer the following question given this paragraph: Sex chromosomes determine sex in animals and many plants. Other chromosomes are called autosomes. Sex-linked traits are controlled by genes on sex chromosomes. They may be inherited differently than autosomal traits. Q: What determines sex in animals? Choices: - cell structure - ribosomes - cell density - sex chromosomes A:
(Answer)
sex chromosomes
Ques: Answer the following question given this paragraph: Air pollution is another significant cause of respiratory disease. The quality of the air you breathe can affect the health of your lungs. Asthma, heart and lung diseases, allergies, and several types of cancers are all linked to air quality. Air pollution is not just found outdoors; indoor air pollution can also be responsible for health problems. Q: Air pollution can cause disease of what system by affecting the health of your lungs? Choices: - excretory - digestive - cardiac - respiratory A:
Ans: respiratory
(Q).
Answer the following question given this paragraph: Make sure formulas of all reactants and products are correct before balancing the equation. Oxygen gas is a diatomic molecule. Potassium oxide is an ionic compound and so its formula is constructed by the crisscross method. Potassium as an ion becomes K + , while the oxide ion is O 2 . Q: What kind of atomic molecule is oxygen gas? Choices: - aromatic - symbiotic - dramatic - diatomic A:
(A).
diatomic
Ques:Answer the following question given this paragraph: 22 Classification of Living Things 22.0.1 Classification of Living Things & Naming With so many flora and fauna on planet Earth, there must be a method to classify each organism to distinguish it from others so it can be correctly identified. Classification does not only apply to biology. For example, supermarkets and grocery stores organise their products by classifying them. Beverages may occupy one aisle, while cleaning supplies may occupy another. In science, the practice of classifying organisms is called taxonomy (Taxis means arrangement and nomos means law). The modern taxonomic system was developed by the Swedish botanist Carolus (Carl) Linneaeus (1707-1788). He used simple physical characteristics of organisms to identify and differentiate between different species. Linneaeus developed a hierarchy of groups for taxonomy. To distinguish different levels of similarity, each classifying group, called taxon (pl. taxa) is subdivided into other groups. To remember the order, it is helpful to use a mnemonic device. The taxa in hierarchical order: . Q: The scientific practice of classifying organisms is also known as what? Choices: - taxodermy - terminology - methodology - taxonomy A:

Ans:taxonomy
Ques:Answer the following question given this paragraph: In physics, resistance is opposition to the flow of electric charges in an electric current as it travels through matter. The SI unit for resistance is the ohm. Resistance occurs because moving electrons in current bump into atoms of matter. Resistance reduces the amount of electrical energy that is transferred through matter. That's because some of the electrical energy is absorbed by the atoms and changed to other forms of energy, such as heat. You can see an animation of resistance at the level of atoms and electrons at this URL: http://www. physics. org/explorelink. asp?id=1738&q=electricalresistance&currentpage=1&age=0&knowledge=0&item=3. Q: In physics, resistance is opposition to the flow of what? Choices: - temperature charges - capacitance - surface flow - electrical charges A:

Ans:
electrical charges
