What are the correct answers to this page of questions?

28. Listed below are four biologically-relevant disaccharides and the hypothetical products of Lactose Alucbe balarto ii Maltose-7wo iii. Sucrose their hydrolysis: se7vve a(A· 1erae two aldoses two ketoses one aldose and one ketose c. Match the disaccharide on the left with the appropriate products on the right 29. Du ring a research excursion to study volcanoes in the South Pacific, you are surprised to discover a previously unknown single-celled life form in an environment of high heat, high pressure, and no oxygen. Without doing any genetic or biochemical testing, which one of the following predictions would you be least likely to make with any certainty? A. The organism could be in the bacterial domain B. None of the ribosomes in the organism are bound to a biological membrane C. The DNA of the organism is found in circular form. D The plasma membrane of the organism is surrounded by a cell wall. E. All of the above predictions could be made with reasonable certainty 30. Consider the following two statements about lipids: 1) Lipids are categorized more by a physical property than by a defined chemical structure 2) A glycerol molecule esterified to three fatty acids is called an oil if it is liquid at room temperature Determine which one of the options below is correct B. C. D. Statement I) and statement 2) are both true. Statement 1) and statement 2) are both false. Statement 1) is true; statement 2) is false. Statement 1) is false; statement 2) is true 14

Explanation / Answer

a) lactose on hydrolysis produce glucose and galactose and both glucose and galactose contain aldehyde group so they yield both aldoses.

B)maltose is made up of two molecules of glucose so it also produce two molecules of aldehyde because glucose is aldoses

C)sucrose=glucose+Fructose

Glucose is aldoses and Fructose is ketoses

So one molecule of aldoses and other ketoses

D)cellobiase is made up of two glucose molecula which are aldoses

29)the plasma membrane is highly evolved and it is covered by cell wall in the kingdom plants and cell wall is found in highy evolved oraganism of plant kingdom so we cannot see it in primitive organism.

30)both are true because lipids which are having same chemical property can behave as a oil at different temperature.so we can category them by physical property

And the second option define the oil .
