The row major components of the cellular member are Lipids a

The row major components of the cellular member are: Lipids and carbohydrates Proteins and carbohydrates Lipids and proteins Nucleic acids and proteins. The gene theory states that all information that specifies organism is in: Polypeptide chains. Polycarbohydrate chains. Glycoproteins. DNA molecules. Phospholipids molecules. Choose the pair of terms that correctly completes this sentence: Nucleotides are to as are to proteins. Nucleic acids; amino acids. Amino acids; polypeptides. Glycosidic linkages; polypeptide bonds. Genes; enzymes. Simple sugars; fatty acids. Unsaturated fats are differed from saturated by: They have two glycerol molecules in their structure. They have double bonds between their carbon atoms. They are hydrophilic, whereas saturated fats are hydrophobic. They can be dissolved in water, whereas saturated cannot. Unsaturated fats always have carbon ring structure in molecule, whereas saturated do not The cell theory states that: All organisms are made of cells. All cells come from other preexisting cells. Cell is a smallest unit of life. A and B only are correct. All of the above are correct. A good example of a positive homeostatic feedback mechanism would be: Regulation of the glucose level in the blood. Regulation of calcium level in body fluids. Enhancement of labor contraction during delivery. Regulation of body temperature. Regulation of blood pressure.

Solution

36. Ans: C

Main components of cell membrane are lipids (phospholipid, cholesterol), proteins and carbohydrate group attached to the lipid and proteins.

Cell membrane of typical human cell contain 50% protein of the total composition by mass, 40% lipids and 10% of carbohydrate.

37. Ans: C

Gene theory says that traits (heredity characters) are transferred from parents to their generation (offspring) through gene transmission. Genes are made up of DNA molecules and located on chromosome.

38. Ans: A

Nucleotides are the subunit of nucleic acid and these units after polymerization form nucleic acids which may be DNA or RNA. Nucleotides made up of three component ribose sugar, nitrogenous base (Adenine, guanine, cytosine, urecil and thymine) and phophate groups.

Amino acids are the building blocks of protein. After polymerization amono acids forms polypeptide chains by formation of peptide bonds.

39. Ans:B

Unsaturated fats are differ from saturated fats by their chemical structure. Unsaturated fates contain one or more double bonds. On the basis of double bonds they are categories in Monounsaturated and Poly unsaturated fates.
