Name:Date:BiologyActive Vs. Passive Transport1. The diagram below represents the major parts of a growing onion plant. Nutrients arerepresented in the soil around the onion.Which statement best describes how nutrients enter the root cells ofthe onion plant?1.Only nutrients needed by the plant enter root cells.2.The nutrients usually move from an area of high concentration inthe soil to an area of low concentration in root cells.3.Nutrients always move into the plant cells by active transport.4.The nutrients always move from an area of low concentration in thesoil to an area of high concentration in root cells.2. The processes of diffusion and active transport are both used to1.break down molecules to release energy2.move molecules into or out of cells of the body3.bring molecules into cells when they are more concentrated outside of the cell4.move molecules against a concentration gradient, using ATP molecules Show

This process of mass flow caused by leaf transpiration explains how most plant nutrients (98 percent) move from the soil to the root surface.
When comparing characteristics of two organisms which evidence would be considered the strongest for supporting a possible genetic relationship?Comparing DNA
Similar DNA sequences are the strongest evidence for evolution from a common ancestor. Look at the diagram in Figure 9.3. 5. The diagram is a cladogram, a branching diagram showing related organisms.
What is one reason why a person's heart rate increases during exercise?During exercise, your heart typically beats faster so that more blood gets out to your body. Your heart can also increase its stroke volume by pumping more forcefully or increasing the amount of blood that fills the left ventricle before it pumps.
Which part of the microscope should the student use to bring the image into focus?Compound Microscopes
Look at the objective lens (3) and the stage from the side and turn the focus knob (4) so the stage moves upward. Move it up as far as it will go without letting the objective touch the coverslip. Look through the eyepiece (1) and move the focus knob until the image comes into focus.
