Nitrogen Cycle Questions 1. Nitrogen is both the __most abundant element__ and in organisms it is the raw material of two main macromolecules __ammonia and nitrite which build proteins and _nitrates which build your genetic material‚ DNA. 2. In the atmosphere it is found in the form of N2 which is __nitrogen gas____. 3. These Nitrogen molecules then need to go through a process called __nitrogen fixation__ in order to be converted into molecules that living organisms can use readily. 4. Two forms

Name___ Chapter 16-Lymphatic System & Immunity Take Home Quiz 1. Explain the functions of the lymphatic system. Transports excess fluid to the bloodstream‚ absorbs fats‚ and helps the body defend against disease causing agents. 2. Trace the general pathway of lymph from the interstitial spaces to the bloodstream. The lymphatic capillary network is found next to the systemic and pulmonary capillary networks. It then travels through lymph vessels into lymph nodes. It returns to lymph vessels

Question 1 In a resting state‚ the axon is polarized‚ with mostly positively charged ions outside and negatively charged ions inside. Question 2 In the brain‚ learning occurs as experience strengthens certain connections in cell work groups called neural networks. Question 3 When the effect of one factor (such as environment) depends on another (such as heredity)‚ we say there is a(n) ________ between the two factors. interaction Question 4 Chromosomes are composed of a coiled

AP Biology Lab 1 Ross Lordo Introduction Questions 1. The solute potential would be -2.48. If the concentration inside the cell is .15 M‚ then would diffusion out of the cell and into the solution of .1 M. This is due to water potential and the tendency for water to move from areas of high water potential to low water potential. 2. The turgor pressure must be equal to the water potential if there is no net diffusion. The cell and environment have reached equilibrium and the movement of water
