Fungi can reproduce either of the two depending on the growth condition of the fungi. If the growth condition is stable, the fungi undergoes asexual reproduction. In asexual reproduction, the mycelium produces haploid spores via mitosis. These spores then spread themselves by air, water or other organisms. Once the spores landed on a place with stable growth condition, they will develop into new hyphaes. On the other hand, if the growth condition keeps changing, the fungi will exhibit sexual reproduction. Two haploid mycelia will fuse via plasmogamy and karyogamy, thus creating a diploid spore. This spore then produces haploid daughter cells via meiosis, which can then be developed into new hyphaes. | 0.259223 |

A material will change from one state or phase to another at specific combinations of temperature and surrounding pressure. Typically, the pressure is atmospheric pressure, so temperature is the determining factor to the change in state in those cases. The states of matter shown are ice (solid), water (liquid) and water vapor (gas). When heat is applied to a material, its change in state typically goes from solid to liquid to gas. There are some exceptions where the material will go directly from a solid to a gas. When a material is cooled, its change in state typically goes from gas to liquid to solid. There are some exceptions where the material will go directly from a gas to a solid. | 0.284817 |

Changes of state are physical changes in matter. They are reversible changes that do not involve changes in matters chemical makeup or chemical properties. They occur when matter absorbs or loses energy. Processes in which matter changes between liquid and solid states are freezing and melting. For a solid to change to a liquid, matter must absorb energy from its surroundings. Freezing happens when the water cools and loses energy until they remain in fixed positions as ice. Processes in which matter changes between liquid and gaseous states are vaporization, evaporation, and condensation. Processes in which matter changes between solid and gaseous states are sublimation and deposition. | 0.281249 |

Ionic bonding is a type of chemical bond that occurs between a metallic atom and a nonmetallic atom that join together to form an ionic compound. In the figure, the metallic atom is the sodium atom and the nonmetallic atom is the chlorine atom. During iconic bonding, the metallic atom gives up an electron to the nonmetallic atom. The sodium atom therefore loses an electron while the chlorine atom gains an electron. Because of the electron transfer, each atom now has an unequal number of electrons and protons, thereby becoming an electrically charged ion. An atom that has lost an electron becomes an ion with a positive charge. A positive ion is called a cation. An atom that has gained an electron becomes an ion with a negative charge. A negative ion is called an anion. In short, the sodium atom becomes a sodium cation, whereas the chlorine atom becomes a chloride anion. (Chlorine becomes chloride when it gains an electrical charge.) Because the two ions have opposite electrical charges, they become attracted to each other and bond together, forming the ionic compound sodium chloride. | 0.275742 |

Thats because state of matter is a physical property. As a result, when matter changes state, it doesnt become a different kind of substance. For example, water is still water whether it exists as ice, liquid water, or water vapor. | 0.726136 |

Is an object reflecting only red light? | a | DD_0274 | image | teaching_images/human_system_eye_2876.png | This picture shows the parts of the eye. The light enters the eye through the pupil. The cornea covers the eye and protects it from damage. The iris controls the size of the pupil. The size of the pupil changes based on the amount of light that enters the eye. The lens projects the image onto retina. The retina has nerve cells which transmit color and other information to the brain. The space between the lens and Retina is filled by a transparent liquid called Viterous gel. Fovea has the highest concentration of cone cells.

Is an object reflecting only red light? | a | DD_0039 | image | teaching_images/earth_moon_phases_2736.png | Illustrated in the diagram are the 8 different phases of the moon. The moon does not produce its own light. However, the moon becomes visible to us due to its capability to reflect light from the sun. As it moves around the Earth, we see these phases that result from the different angles the moon makes with the sun. A New Moon occurs when the side of the moon facing the earth is not illuminated by the sun. After a few days, a thin crescent shape of the moon becomes visible in the night sky. The crescent moon waxes, or appears to grow fatter, each night. When half of the moon is illuminated, it is called a First Quarter moon. The moon continues to wax, forms a gibbous shape, until it eventually becomes a Full Moon. This now means that the moon has completed one half of a month. During the second half, the shape of the moon starts to wane, growing thinner every night. Once the moon reaches the Third Quarter, it shows the other half of its disc that is illuminated by the sun. It continues to wane while nearing its approach to the New Moon Phase. The Moon undergoes a complete cycle of phases about every 29.5 days. | 0.249003 |

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. | 0.233797 |
