Answer the following question given this paragraph: Schrodinger's work on orbitals is the basis of the modern model of the atom, which scientists call the quantum mechanical model. The modern model is also commonly called the electron cloud model. That's because each orbital around the nucleus of the atom resembles a fuzzy cloud around the nucleus, like the ones shown in the Figure below for a helium atom. The densest area of the cloud is where the electrons have the greatest chances of being. Q: The modern model of the atom, which scientists call the quantum mechanical model, is based on what scientist's work on orbitals? Choices: - Sagan - Bohr - Newton - schrodinger A:
schrodinger

Answer the following question given this paragraph: Skeletal system problems include osteoporosis, bone fractures, and ligament sprains. A diet rick in calcium and vitamin D may reduce the risk of osteoporosis and related bone fractures. Following safe practices may also reduce the risk of fractures as well as sprains. Q: A diet rich in calcium and what vitamin may reduce the risk of osteoporosis and related bone fractures? Choices: - niacin - vitamin A - vitamin C - vitamin d A:
(Answer)
vitamin d
Ques: Answer the following question given this paragraph: Bacteria can be used to make cheese from milk. The bacteria turn the milk sugars into lactic acid. The acid is what causes the milk to curdle to form cheese. Bacteria are also involved in producing other foods. Yogurt is made by using bacteria to ferment milk ( Figure below ). Fermenting cabbage with bacteria produces sauerkraut. Q: Bacteria can be used to make cheese from milk. the bacteria turn the milk sugars into what? Choices: - acetic acid - ionic acid - hydrochloric acid - lactic acid A:
Ans: lactic acid
(Q).
Answer the following question given this paragraph: Composite volcanoes usually have craters on the top. Why are the craters sometimes "U" or horseshoe-shaped?. Q: A crater can usually be found on the top of what kind of volcanoes? Choices: - Shield - Dome - Compound - composite A:
(A).
composite
Ques:Answer the following question given this paragraph: For these plants, the name says it all. Vascular seedless plants have vascular tissue but do not have seeds. Remember that vascular tissue is specialized tissue that transports water and nutrients throughout the plant. The development of vascular tissue allowed these plants to grow much taller than nonvascular plants, forming ancient swamp forests. Most of these large vascular seedless plants are now extinct, but their smaller relatives still remain. Vascular tissue includes xylem, which transports water from the roots to the rest of the plant; and phloem, which transports sugars and nutrients from the leaves throughout the plant. Q: What is the specialized tissue that transports water and nutrients throughout the plant and allows these plants to grow taller? Choices: - blood vessels - dioxide tissue - fiber tissue - vascular tissue A:

Ans:vascular tissue
Ques: Answer the following question given this paragraph: Haumea is part of a collisional family. This is a group of astronomical objects that formed from an impact. This family has Haumea, its two moons, and five more objects. All of these objects are thought to have formed from a collision very early in the formation of the solar system. Q: What kind of family is haumea part of? Choices: - eoan family - a moclobemide family - orbital family - a collisional family A:
Ans:
a collisional family
