L_0453 | asexual vs. sexual reproduction | T_2732 | FIGURE 1.4 Fungi can also reproduce sexually, but instead of female and male sexes, they have (+) and (-) strains. When the filaments of a (+) and (-) fungi meet, the zygote is formed. Just like in plants and animals, each zygote receives DNA from two parent strains. | image | textbook_images/asexual_vs._sexual_reproduction_21716.png |
L_0455 | b and t cell response | T_2737 | FIGURE 1.1 This diagram shows how an antibody binds with an antigen. The antibody was produced by a B cell. It binds with just one type of antigen. Antibodies produced by different B cells bind with other types of antigens. The antigen-binding sites can vary, such that they are specific for just one antigen. | image | textbook_images/b_and_t_cell_response_21719.png |
L_0455 | b and t cell response | T_2738 | FIGURE 1.2 In this diagram, a killer T cell recognizes a body cell infected with a virus. After the killer T cell makes contact with the in- fected cell, it releases poisons that cause the infected cell to burst. This kills both the infected cell and the viruses inside it. | image | textbook_images/b_and_t_cell_response_21720.png |

L_0475 | cell biology | DD_0199 | This diagram all comes down to one thing; that is cells are the building blocks of life. Cells are the functioning units of living things. All cells share certain common components. These parts are cytoplasm, cell membrane, ribosome and DNA. The DNA is the specific instructions or makeup which explains that specific cell. There are many different types of cells. Some cells in this diagram include blood cells, skin surface cells, bone cells, neuron, smooth muscle cells, cardiac muscle cell, skeletal muscle cell and columnar epithelial and goblet cells. These cells all help makeup the human body. | image | teaching_images/types_cells_7640.png |
L_0475 | cell biology | DD_0200 | This diagram shows some of the specialized cells in the human body. The red blood cells carry oxygen to the other cells in the human body. The columnar epithelial cells form the inner lining of the human intestine. The smooth muscle cells are found in the lining of arteries, veins and blood vessels. They help is contraction and relaxation of the body part they are found in. The bone cells are found in the bone tissue and help in building up the human skeleton. The nerve cells are found in the brain, spinal cord and nerves. They process and transmit information through electrical and chemical signals. The ovum and sperm cell help in reproduction. The function of a sperm cell is to swim through fluid to an ovum cell. | image | teaching_images/types_cells_7639.png |
L_0476 | cell cycle | T_2806 | FIGURE 1.1 resulting in two cells. After cytokinesis, cell division is complete. The one parent cell (the dividing cell) forms two genetically identical daughter cells (the cells that divide from the parent cell). The term "genetically identical" means that each cell has an identical set of DNA, and this DNA is also identical to that of the parent cell. If the cell cycle is not carefully controlled, it can cause a disease called cancer in which the cells divide out of control. A tumor can result from this kind of growth. | image | textbook_images/cell_cycle_21758.png |

The hy- drophilic ("water-loving") head and two hydrophobic ("water-hating") tails are shown. The phospholipids form a bilayer (two layers). The middle of the bilayer is an area without water. There can be water on either side of the bilayer. There are many proteins throughout the membrane. | image | textbook_images/cell_membrane_21760.png |

This figure shows the complexity of the coiling process. The red dot shows the location of the centromere, which holds the sis- ter chromatids together and is where the spindle microtubules attach during mitosis and meiosis. Notice that a chromosome resembles an "X." | image | textbook_images/mitosis_and_cytokinesis_21989.png |
L_0602 | mitosis and cytokinesis | T_3182 | FIGURE 1.2 After telophase, each new nucleus contains the exact same number and type of chromosomes as the original cell. The cell is now ready for cytokinesis, which literally means "cell movement." During cytokinesis, the cytoplasm divides and the parent cell separates, producing two genetically identical cells, each with its own nucleus. A new cell membrane forms and in plant cells, a cell wall forms as well. Below is a representation of dividing plant cells ( Figure 1.3). | image | textbook_images/mitosis_and_cytokinesis_21990.png |

The contacts in a PV cell are like the terminals in a chemical cell. One contact is negative and the other contact is positive, creating a difference in electric potential, or volt- age, which produces electric current. | image | textbook_images/electric_current_22474.png |

L_0759 | electric circuits | DD_0225 | In this figure, you see a Series and a Parallel circuit. The circuits are composed of one battery, two lamps and wires. The battery provides the required voltage for these circuits, and the wire is used to conduct the electricity between different components of the circuit. The Series circuit is shown on the left and the Parallel circuit is shown on the right. There is only one loop in the Series circuit, while the Parallel circuit has two loops. The lamps in the Series circuit will be turned off if one of the circuit components get disconnected. However, one of the lamps in the Parallel circuit will remain on even if the other lamp is disconnected. | image | teaching_images/circuits_1056.png |
L_0759 | electric circuits | DD_0226 | The diagram we see here is that of an electric circuit. There are four components in this circuit - the battery, the switch, the wire and the light bulb. The light bulb shall work only when it is connected to the battery. If the wire is connected loosely, the light bulb won't light because electric current needs a smooth path to flow the current. Wire is a very essential component as the current flows through the wire. Charges must have an unbroken path to follow between the positively and negatively charged parts of the voltage source, in this case, the battery. Electric current cannot flow through an open circuit. A switch controls the flow of current through the circuit. When the switch is turned on, the circuit is closed and current can flow through it. When the switch is turned off, the circuit is open and current cannot flow through it. | image | teaching_images/circuits_228.png |
L_0759 | electric circuits | DD_0227 | The diagram shows both an open and closed circuit. Each circuit contains wires connected to each terminal of the battery along with a light bulb. Each battery contains two terminals, a positive and negative. The positive side is shown with a plus symbol. In the closed circuit, electrons are allowed to flow and illuminate the light bulb. The flow of electrons are shown by the arrows from the positive to the negative terminal through the light bulb. In the open circuit, the wire connected to the negative terminal is not connected to the light bulb. This prevents electrons from flowing through the circuit and the light bulb does not get illuminated. | image | teaching_images/circuits_1578.png |
L_0759 | electric circuits | DD_0228 | The diagram shows a parallel circuit with a battery and 4 resistors. A parallel circuit has two or more paths for current to flow through. All electric circuits have at least two parts: a voltage source and a conductor. The voltage source of the circuit in the diagram is a battery. Voltage is the same across each component of the parallel circuit. The conductor must form a closed loop from the source of voltage and back again. From the diagram, the wires are connected to both terminals of the battery, so they form a closed loop. The diagram also has 4 resistors, which can be any device (such as a lightbulb) that converts some of the electricity to other forms of energy. | image | teaching_images/circuits_1547.png |
L_0759 | electric circuits | DD_0229 | This diagram shows an open circuit. It consists of a bulb, a battery and wires connecting the bulb to the battery. The battery has two terminals, a positive and a negative terminal. A and B are the ends of the wire. In this diagram, A and B are not connected to each other. Hence the circuit is called an open circuit. Electric current cannot flow through an open circuit. Hence the bulb will not light up. If the ends of the wires, A and B were connected to each other, the circuit would be known as a closed circuit. Electric current would flow through this closed circuit which would lead the bulb to be lit. | image | teaching_images/circuits_224.png |
