When water freezes, it forms a lattice crystal, causing ice to float. Large bodies of water stabilize climates due to water's high specific heat. The polarity of water's bonds allows for covalent bonding between molecules. Hydrogen bonding results in water having strong cohesive and adhesive properties. Correct Answer The polarity of water's bonds allows for covalent bonding between molecules. Which biologic molecule would you recommend a patient limit if they want to avoid having cardiovascular problems? Unsaturated fats Carbohydrates Phospholipids Saturated fats Correct Answer Saturated fats DNA and RNA are subunits of which type of biologic molecule? Proteins Lipids Nucleic acids Carbohydrates Correct Answer Nucleic acids Which type of protein acts to catalyze different reactions or processes? Amino acids Enzymes Steroids Hormones Correct Answer Enzymes What are the three types of lipids? Fatty acids, enzymes, and steroids Fatty acids, phospholipids, and enzymes Fatty acids, saturated fats, and unsaturated fats Fatty acids, phospholipids, and steroids Correct Answer Fatty acids, phospholipids, and steroids In a cell, reactions take place in a series of steps called ____________? catabolic pathways metabolic pathways the electron transport chain cellular respiration Correct Answer metabolic pathways What function do cholesterol molecules serve within the cell membrane? They allow for carbohydrate chains to extend beyond the cell membrane to communicate with other cells. They allow the cell membrane to be selectively permeable by making the bilayer structure more flexible. They act as transport highways for molecular movement into and out of the cell. They stabilize the flexible bilayer structure to prevent breakage. Correct Answer They stabilize the flexible bilayer structure to prevent breakage. Although animal cells lack cell walls, they do have an elaborate
