WGU C190 Intro to Bio - Exam Practice Ques tions Water molecules binding to each other is called _______; wa ter molecules binding to other molecules is called _______. - ✔✔Cohesion; adhesion Water molecules form hydrogen bonds because water is - ✔✔Polar Water can bind to the walls of these cells because they are _____ When water binds to the walls of the cells , this is called ________ - ✔✔Polar; adhesion Water molecules within these cells will also bind to each other. What is this called? - ✔✔Cohesion Dissolving sugar in water makes a _______. The sugar is the _____ and the water is the _____ - ✔✔Solution; so lute; solvent As water moves up the plant, it carries matter with it (such as nutrients and some hormones). What are these materials called? - ✔✔Solutes What characteristic of water allows a paperclip to float on the surface of the water. - ✔✔Surface tension Why does mercury (Hg) not travel as far up the capillary tube as water does? - ✔✔Mercury is not as adhesive as water If the plant gets too dry, the water column can break. This creates an air bubble in the xylem. What happens to the water when the a ir bubble forms? - ✔✔The water is still adhering to the xylem walls, but the water column is no longer continuous. Explain why plants produce smaller cells during dry seasons. - ✔✔The smaller cells are more resistant to air bubbles. Explain why plants pr oduce larger cells during wet seasons. - ✔✔These cells can transport more water. Organic molecules take many different shapes. This is because: - ✔✔Carbon can form up to four covalent bonds with other molecules, allowing for a variety of structures Which of the following molecules might be broken down (hydrolyzed) to produce simple sugars? Select all that apply; more than one is correct. - ✔✔Maltose (a disaccharide), cellulose, starch Which molecule is abundant in seeds and is easily digested to yie ld glucose? - ✔✔Starch
