Q: Answer the following question given this paragraph: Figure 5.7 Not all cells of a leaf carry out photosynthesis. Cells within the middle layer of a leaf have chloroplasts, which contain the photosynthetic apparatus. (credit "leaf": modification of work by Cory Zanker). Q: Not all cells of a leaf carry out photosynthesis. cells within the middle layer of a leaf have chloroplasts, which contain the photosynthetic what? A:

OPTIONS:
- pipes
- structure
- wires
- apparatus

A: apparatus

input: OPTIONS:
- chemical reactions
- change in temperature
- microscopic inspection
- measured energy changes Now, answer this question: Answer the following question given this paragraph: There are a number of different ways to measure the strength of a given crystal lattice. One way would be to measure the amount of energy needed to completely pull apart an ionic substance into isolated ions. This value, known as the lattice energy , cannot be measured directly, but it can be calculated based on measured energy changes for other more feasible processes. The lattice energy of an ionic solid provides us with one way to measure the relative strength of the ionic bonds in that compound. Table below shows the lattice energies for various ionic substances:. Q: Lattice energy cannot be measured directly. what is its calculation based on? A:
A:
output: measured energy changes

Answer the following question given this paragraph: The cell wall is located outside the cell membrane. It consists mainly of cellulose and may also contain lignin, which makes it more rigid. The cell wall shapes, supports, and protects the cell. It prevents the cell from absorbing too much water and bursting. It also keeps large, damaging molecules out of the cell. Q: Where is the cell wall located? A:

OPTIONS:
- in cell membrane
- in the chloroplast
- in the mitochondria
- outside cell membrane

Answer: outside cell membrane

Problem: OPTIONS:
- bronchial circulation
- respiratory system
- kidneys
- pulmonary circuit
Q: Answer the following question given this paragraph: Figure 19.4 Dual System of the Human Blood Circulation Blood flows from the right atrium to the right ventricle, where it is pumped into the pulmonary circuit. The blood in the pulmonary artery branches is low in oxygen but relatively high in carbon dioxide. Gas exchange occurs in the pulmonary capillaries (oxygen into the blood, carbon dioxide out), and blood high in oxygen and low in carbon dioxide is returned to the left atrium. From here, blood enters the left ventricle, which pumps it into the systemic circuit. Following exchange in the systemic capillaries (oxygen and nutrients out of the capillaries and carbon dioxide and wastes in), blood returns to the right atrium and the cycle is repeated. Q: Blood flows from the right atrium to the right ventricle, where it is pumped into the what? A:
Answer: pulmonary circuit

Problem:OPTIONS:
- hypothesis
- observation
- theory
- evidence

Answer the following question given this paragraph: The term theory is used differently in science than it is used in everyday language. A scientific theory is a broad explanation that is widely accepted because it is supported by a great deal of evidence. Because it is so well supported, a scientific theory has a very good chance of being a correct explanation for events in nature. Because it is a broad explanation, it can explain many observations and pieces of evidence. In other words, it can help connect and make sense of many phenomena in the natural world. Q: What allows theories to be widely accepted? A:
****
A: evidence

Problem:OPTIONS:
- size
- variation
- precipitation
- temperature

Answer the following question given this paragraph: There are other units in chemistry that are important, and we will cover others in the course of the entire book. One of the fundamental quantities in science is temperature. Temperature is a measure of the average amount of energy of motion, or kinetic energy, a system contains. Temperatures are expressed using scales that use units called degrees, and there are several temperature scales in use. In the United States, the commonly used temperature scale is the Fahrenheit scale (symbolized by F and spoken as "degrees Fahrenheit"). On this scale, the freezing point of liquid water (the temperature at which liquid water turns to solid ice) is 32F, and the boiling point of water (the temperature at which liquid water turns to steam) is 212F. Science also uses other scales to express temperature. The Celsius scale (symbolized by C and spoken as "degrees Celsius") is a temperature scale where 0C is the freezing point of water and 100C is the boiling point of water; the scale is divided into 100 divisions between these two landmarks and extended higher and lower. By comparing the Fahrenheit and Celsius scales, a conversion between the two scales can be determined: C=(F32)59 Saylor URL: http://www. saylor. org/books.
