Answer the following question given this paragraph: In trees, some of the epidermal tissue is replaced by bark. Bark is a combination of tissues that provides a tough, woody external covering on the stems of trees. The inner part of bark is alive and growing; the outer part is dead and provides strength, support, and protection. Q: What is the combination of tissues that provides a tough, woody external covering on the stems of trees called? Choices: - cuticle - scale - epidermis - bark A:
bark

Ques: Answer the following question given this paragraph: CHAPTER SUMMARY 30.1 The Plant Body A vascular plant consists of two organ systems: the shoot system and the root system. The shoot system includes the aboveground vegetative portions (stems and leaves) and reproductive parts (flowers and fruits). The root system supports the plant and is usually underground. A plant is composed of two main types of tissue: meristematic tissue and permanent tissue. Meristematic tissue consists of actively dividing cells found in root and shoot tips. As growth occurs, meristematic tissue differentiates into permanent tissue, which is categorized as either simple or complex. Simple tissues are made up of similar cell types; examples include dermal tissue and ground tissue. Dermal tissue provides the outer covering of the plant. Ground tissue is responsible for photosynthesis; it also supports vascular tissue and may store water and sugars. Complex tissues are made up of different cell types. Vascular tissue, for example, is made up of xylem and phloem cells. Q: A plant is composed of two main types of tissue: meristematic tissue and what other kind of tissue? Choices: - synovial tissue - muscle tissue - nonvascular tissue - permanent tissue A:
Ans: permanent tissue

Answer the following question given this paragraph: Investigation is at the heart of science. It is how scientists do research. Scientific investigations produce evidence that helps answer questions and solve problems. If the evidence cannot provide answers or solutions, it may still be useful. It may lead to new questions or problems for investigation. As more knowledge is discovered, science advances. Q: In science, what process produces evidence that helps answer questions and solve problems? Choices: - information - manipulation - suspension - investigation A:
(A).
investigation

Ans:neutral
Ques:Answer the following question given this paragraph: Mechanical energy is the energy of an object that is moving or has the potential to move. It is the sum of an object's kinetic and potential energy. In Figure below , the basketball has mechanical energy because it is moving. The arrow in the same figure has mechanical energy because it has the potential to move due to the elasticity of the bow. What are some other examples of mechanical energy?. Q: What term describes the energy of an object that is moving or has the potential to move? Choices: - stationary energy - molecular energy - thermal energy - mechanical energy A:

Ans:
mechanical energy
