What are the products of anaerobic respiration in yeast? Alcohol and Carbon dioxide Which layer of the Earth is composed primarily of solid rock? Crust Which mirror is used for side view in vehicles? Convex Concave Lenses Are for the Nearsighted, Convex for the Farsighted The convex shape of the mirror causes light rays to diverge, resulting in a wider view Acids Taste Sour. Acids are known to have a sour taste. This is a common characteristic of acidic substances, such as lemon juice and vinegar, which contain citric acid and acetic acid, respectively. This sourness is a typical property used to describe acids. Therefore, the statement "Acids taste sour" is true. What is the role of the mitochondria in animal cells? To convert glucose into energy Mitochondria are often referred to as the powerhouses of the cell. They are specialized organelles within animal cells that play a critical role in converting the energy stored in glucose into ATP (adenosine triphosphate) through a process known as cellular respiration. ATP is the main energy currency of cells, used to power various biological processes such as muscle contraction, nerve impulse propagation, and chemical synthesis. The Standard International Unit of Speed m/s capability of being shaped or extended by hammering, forging, etc Malleability Iron and Aluminum The property of the metals to be drawn into thin wires is called Ductility Copper What do you call the amount of space occupied by a matter? Volume What do you call the amount of matter inside an object? Mass The following are properties that are common to all matter except Force It is the ability of solid to resist scratching or breaking Hardness. It is the property that makes solids easy to break. Brittleness. What do you call the ability of liquids to flow? Fluidity Solid, liquid and gas are different states of matter. It can change its state by changing its temperature. What do you call the change of state in matter Phase Change What is the standard unit of measurement in temperature? Celsius What do you call the temperature at which solid starts to melt? Melting Point It is the process of changing liquid object to solid such as water to ice cubes Freezing What do you call the process of changing liquid to gas, such as the vaporin a boiling water? C. Evaporation It undergoes a change from solid to gas. What do you call this phase change? A. sublimation What do you call the process that changes gas to liquid? B. condensation What do you call the process in which gaseous materials change into solid without passing through the liquid phase?. Deposition What do you call the process of food-making among plants? Photosynthesis These are animals that only eat plants just like cows, goats, horses and rabbits. C. Herbivores Lions, tigers, sharks and snakes consume only meat or flesh in order for them to survive. What group of animals do they belong? B. Carnivores Other animals like bears, monkeys as well as human eat both plants and animal flesh or meat in order to survive. What do you call this group? A. Omnivores What do you call the instant reaction that you do as response to a certain stimulus? Reflexes It is the transparent film-like covering of the eye that controls and focus the amount of light entering it Cornea The colorful part of the eye that regulates the amount of light that can enter the pupil Iris It is the center opening of the IRIS where light enters our eyes PUPIL It is a clear and colorless part behind the iris that receives the light that enters through the pupil LENS It is the part of eye located at the back which receives the light from thelens. The image that is form in this part is inverted RETINA It is the white part of the eye that surrounds the pupil and iris SCLERA The nerve that sends message to the brain regarding the visual image that we see Optic Nerve This is an infection that makes the eyes pinkish, itchy, sore and painful. Sore Eyes What is the other term for Farsightedness? Hyperopia An eye condition where a person sees near objects very clearly. Howeverobjects that are far away will appear blurry. What do you call this condition? Nearsightedness or Myopia An eye condition that is caused by a curved eyeball or an irregularly-shaped cornea that blurs one’s vision. This condition results in the inability of the eye to focus on an object A. ASTIGMATISM It sends sound signals to the brain Auditory Nerve The nerve that sends smell signals to the brain are called Olfactory nerve It is the outer layer of the skin Epidermis Part of the skin below the epidermis Dermis What gland in the dermis that produces sebum which serves as skin’s natural lubricant? Oil Glands It is the largest organ in the body. Skin Is the natural environment where animals live, find food and interact with other animals HABITAT Sunlight is white light. White light is a mixture of many colors. What is formed when white light passes through some transparent materials? Rainbow The smallest galaxies are called ______ and the largest are called ___ dwarf spheroidal and giant ellipticals Our Sun is just one of many millions of stars in a group of stars called a… Galaxy The unit of length that astronomers use is the… Meters Current evidence suggests that most of the mass of the universe is in the form of… DARK MATTER What is the largest planet in our solar system? Jupiter Which planet in our solar system has massive rings that are easily visible with a small telescope? Saturn Mars is often called “The Red Planet,” but why does it look so red to begin with? The surface has a lot of iron which turns orange-red when it rusts How many planets are there in our solar system? Eight How long does it take for light from the Sun to reach Earth 8 Minutes Bond that shares electrons covalent bond Bond that donates electrons Ionic bond 3. Which of the following makes a heterogenous mixture? Oil and Water 5. Which of the following parts allow different activities of the cell to happen? Cytoplasm 6. What part of the cell stores water and maintain its rigidity? Vacoule 7. What does the slope of a distance VS. time graph represent? Speed 8. This refers to the shortest distance between the object's two positions. Displacement Which part in the atmosphere that protects us against the sun's harmful radiation? Stratosphere 2. It is a reaction between ar acid and a base forming salt and water. Neutralization 2. The word atom is from a Greek word meaning: indivisible 6. The heart, brain, and stomach are made up of groups of: Tissue The atoms we study are neutral, which means they have the same number of protons and electrons what is the biggest group on the periodic table metals Hg in periodic table is Mercury is the only metal that is a liquid at room temperature.
