Question
Which statement is an accurate description of water molecules? C they are uncharged and polar A they are charged and polar D. they are uncharged and nonpolar B they are charged and nonpolar E. they are ionically bonded 4 Organic molecules always B contain carbon, bydrogen, and oxygen respectively in a 1:2.1 ratio D. dissolve in water carbon, hydrogen, and oxygen respectively in a 1:2:1 ratio A contain carbon C. are produced by living organisms E are hydrophobic 5. The primary compounds that are indicative of living organisms are B. carbohydrates, lipids, proteins, nucleic acids A, carbohydrates, lipids, steroids, proteins C sugans, fats, deosymbonucleic acids, enzymes D. sugars,rnbonucleic acids, deoxynibonucleic acids, fas E carbohydrates, lipids, proteins, and enzymes Which unit of organization is indicative of all living organisms A cell B. tissue C. organ D. systemE organelleExplanation / Answer
Ans 3) c) They are uncharged and polar – On stating that the water molecules are polar, it means they are able to form hydrogen bonds. The water molecule is able to interact with each other as they don’t have a charge. It has no net charge.
Ans 4) c) are produced by living organisms. It is a large group of chemical compounds that consists of one or more atoms of carbons covalently linked to atoms of other elements like hydrogen, oxygen or nitrogen. They are only found in living organism.
Ans 5) The primary compounds that are indicative of living organisms are (b) carbohydrates, lipids, proteins and nucleic acids. They are the building blocks of any organisms and extremely important for survival and growth.
Ans 6) a) Cell – It is the basic unit of life and all the higher parts like tissues or organs or the complete body is formed by cell
