Litmus is a dye extracted from lichens that is used to test a substance’s acidity or alkalinity. When blue litmus paper comes into contact with an acid, it turns red. 3 / 25 The process of cell division can take place by Fusion None of these Heterosis Mitosis Cell division can take place by mitosis, which is a process that involves the separation of chromosomes and division of a cell into two new cells. 4 / 25 The power house of energy in cells is Golgi bodies Endoplasmic reticulum Mitochondria Ribosomes Mitochondria are known as the powerhouse of cells. It is because the mitochondrion is the site of cellular respiration where energy in the form of ATP (Adenosine triphosphate) is generated as a result of oxidation of food constituents. This energy is required for various chemical activities needed for life. 5 / 25 The most electropositive element among the following is K Na Cs Ca Cesium (Cs) is the most electropositive element on the periodic table. 6 / 25 Name cancer that starts in the skin or the tissues that line other organs? Carcinoma None of the above Leukemia Pancreas Carcinoma is a cancer that begins in the skin or in tissues that line or cover internal organs. Sarcoma is a cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue. 7 / 25 The most electronegative element among sodium, bromium, fluorine and oxygen is Fluorine Oxygen Sodium Bromium Fluorine is the most electronegative element of the four, with an electronegativity of 3.98, compared to 0.93 for sodium, 2.96 for bromine, and 3.44 for oxygen. 8 / 25 The astronomical unit (AU) is the mean distance between the surface of the sun to the surface of the earth mean distance from the centre of the sun to the centre of the earth minimum distance between the sun and the earth maximum distance between the sun and the earth An Astronomical Unit (AU) is the average distance between Earth and the Sun, which is about 93 million miles or 150 million kilometers. Astronomical units are usually used to measure distances within our Solar System 9 / 25 The material used for a fuse wire should have High melting point Low melting point High resistivity High ductility A fuse wire is designed to melt quickly when too much current flows through it, which is why a material with a low melting point is essential. Typically, a fuse wire is made from an alloy of lead and tin due to its low melting point and relatively high resistance 10 / 25 Which of the following devices converts electrical energy into mechanical energy? Transformer Electric motor Dynamo Inductor 11 / 25 The so-called fourth state of matter refers to Dry Ice Plasma Mercury LPG Plasma is a super-heated state of matter made of positively charged ions and negatively charged electrons. It’s created when a gas is heated to the point that its electrons separate from the nuclei of its atoms. 12 / 25 The acid present in lemons and oranges is acetic acid oxalic acid citric acid hydrochloric acid Citric acid is found in high concentrations in lemons and limes, making up to 8% of the dry weight of the fruit. It’s also found in other citrus fruits, such as grapefruit. 13 / 25 Lights of different colours are arranged below in order of increasing wavelengths:1. Violet, indigo, blue2. Green, orange, red3. Red, green, indigo4. Blue, green, yellow Which of the above are in proper sequence? 1 and 4 1 and 2 Only 1 2 and 3 The order of visible light colors in increasing wavelength is violet, indigo, blue, green, yellow, orange, and red. This order is commonly remembered by the acronym VIBGYOR. 14 / 25 Lichen is considered to be a symbiotic association of two living organisms. Which organisms are involved in it? Algae and fungi Algae and bryophytes Fungi and bryophytes Algae and bacteria Lichens are a symbiotic association between a fungus and an alga or cyanobacteria. The fungus’s filaments (hyphae) surround the algae or cyanobacteria cells. Some lichens can have three or more partners. 15 / 25 By which of the following methods could a cup of hot coffee lose heat if placed on a metal table in a room? Conduction and convection Conduction, convection, radiation and evaporation Convection and radiation Conduction and radiation A cup of hot coffee on a metal table in a room temperature loses heat by Conduction, Convection and Radiation. Heat leaves the cup of coffee as the steam and air pressure increases. Conduction is the flow of energy from particle to particle by matter. 16 / 25 Which of the following is the universal recipient blood group? A O AB B 17 / 25 Consider the following statements:1. Carbyne is an allotrope of carbon.2. Gasoline, used as a fuel in motor vehicles is a mixture of petrol and alcohol.3. Petroleum is also known as ‘liquid gold’.4. The various components of crude oil are separated by fractional distillation.The correct statements are: 1, 2, 3 and 4 1, 2 and 4 only 1, 3 and 4 only 1, 2 and 3 only 18 / 25 Name the most common type of cancer that kills men in the world? Prostate Cancer Lung cancer Colon and Rectum Cancer Liver Cancer 19 / 25 The mass number of an atom is equal to The number of protons and electrons The number of neutrons The number of protons The number of nucleons The mass number of an atom is equal to the total number of protons and neutrons in its nucleus. It’s also known as the atomic mass number or nucleon number. The mass number is different for each isotope of an element. You can calculate the number of neutrons in an atom by subtracting its atomic number from its mass number 20 / 25 An element with atomic number 36 belongs to the d-block p-block f-block s-block The element with atomic number 36 is krypton (Kr) and it belongs to the noble gas group (group 18) in the periodic table. Krypton is a rare, colorless, odorless, gaseous element that is inert and only forms a few chemical compounds.Krypton is used in fluorescent lights and flash lamps for high-speed photography. It’s also used in bright, high-powered gas lasers, and krypton fluoride is a useful laser medium. 21 / 25 The average pH value of the milk is: 7.4 6.6 6.1 8 The pH of fresh milk is usually between 6.7 and 6.9, which is slightly acidic because of the lactic acid in milk. A significant deviation from this range may indicate spoilage or contamination. 22 / 25 The average pH value of the human blood is: 7.4 8.7 6.2 5.4 The average pH of human blood is 7.40, with a normal range of 7.35 to 7.45. This means that blood is slightly alkaline or basic. 23 / 25 Name cancer that occurs in the bone marrow and creates blood cells? Leukemia Myeloma Sarcoma Lymphoma Leukemia, a type of cancer found in your blood and bone marrow, is caused by the rapid production of abnormal white blood cells. The high number of abnormal white blood cells are not able to fight infection, and they impair the ability of the bone marrow to produce red blood cells and platelets. 24 / 25 Which of the following is not a compound of calcium ? Marble Gypsum Molybdenum Chalk 25 / 25 Water has maximum density at 4°C 0°C 100°C Room temperature Water has its maximum density at 4°C (39.2°F). This is because when water’s temperature increases from 0°C to 4°C, some of its hydrogen bonds break, causing its molecules to move closer together and its volume to decrease. This decrease in volume increases the density of water. Your score isThe average score is 50% 0% Restart quiz Please translate the page, if you want to change the language of quiz.
