Question
The pH of urine is 6.0 and the pH of orange juice is 3.0. The concentration of hydrogen ions is greater in which liquid? They have the same concentration of hydrogen ions. Orange juice Urine All organic compounds contain the element Carbon. True False The DNA double helix holds together because the base pairs on each strand are attracted to each other by __________ bonds. ionic hydrogen covalent Which of the following are macromolecules? (There will be more than one correct answer.) Carbhohydrates Nucleotides Lipids proteins A key source of energy in almost all organisms is glucose, a fuel for cellular respiration and is the product of photosynthesis. True FalseExplanation / Answer
15. higher concentration of H+ means lower ph and lower ph means it's more acidic. Hence orange juice is more acidic and it has higher concentration of hydrogen ion. Hence ORANGE JUICE is the correct answer
16.Organic compounds are chemical substances that make up organisms and carry out life processes.As carbon is the major element in organic compounds, it is essential to all known life on Earth.Answer is TRUE
17.The DNA double helix is held together by two types of bonds, covalent and hydrogen bonds. Covalent bonds occur within each linear strand and strongly bond the bases, sugars, and phosphate groups. Whereas, hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing. These hydrogen bonds are individually weak but collectively quite strong.Hence HYDROGEN is the correct answer
18.Carbohydrades and proteins are macromolecules nucleic acids which are made up of nucleotides are macromolecules Lipids are not considered as true macromolecules as they are not covalently bonded as other macromolecules. CARBOHYDRATES AND PROTEINS are correct answer
19. Glucose is a product for photosynthesis and is utilized for cellular respiration. Hence the statment is TRUE
