Concept explainers
(a)
To determine: The other variable needs to known for calculating the net ecosystem production (NEP) if the NPP is known.
Concept introduction: Net ecosystem production (NEP) is the gross production remain after the loss of total respiration of all the organisms in the system, on the other hand the NPP can be expressed as the amount of novel biomass added by producers in that time.
(b)
To determine: Why it is difficult to measure a variable that involves in net ecosystem production (NEP) ocean.
Concept introduction: Net ecosystem production (NEP) is the gross production remain after the loss of total respiration of all the organisms in the system, on the other hand the NPP can be expressed as the amount of novel biomass added by producers in that time.

- Pick a small area of the cell (NOT THE ENTIRE CELL!) and label and show the following:a. An Na+ gradient (show where Na+ is high and low). Use a triangle to show the gradient from high to low as in the various worksheets for all gradientsb. An K+ gradient (show where K+ is high and low)c. An H+ gradient (show where H+ is high and low)d) For each of the gradients, sketch the location of the protein or proteins that create the gradient and ANY associated reactions that occurarrow_forwardCreate a line weaver burke plot from the following data.arrow_forwardr^2=6Dt , where D is the diffusion coefficient of thediffusing object and t is the time that the object is allowed to diffuse. If the diffusion coefficient, D, of a small protein is 5 x 10^-10 m2 s-1, how long (on average) does ittake for the protein to diffuse across a parasitic wasp that is 189 um long ?arrow_forward
- In an experiment design to test the effects of outboard motor oil on the growth of algae, identify the control, the independent variable, and the dependent variables. Construct a simple hypothesis.arrow_forwardT or farrow_forwardCompare the responses of modular organisms and unitary organisms toenvironmental perturbations. How did plants (growth of mung bean in sunny and shaded) and ants (the ants trail is blocked with a paper to see how they react) respond to the simulated environmental disturbances? Explain their responses in relation to being a modular or unitaryorganism.arrow_forward
- The solutions in the two arms of the U-tube are separated by a membrane that is permeable to water and glucose but not to sucrose. Side A is filled with a solution of 2.0 M sucrose and 1.0 M glucose. Side B is filled with 1.0 M sucrose and 2.0 M glucose. Initially, the solution in side A, with respect to that in side B, is what? After the system reaches equilibrium, what changes are observed?arrow_forwardIn this problem, you will design a filter system for a flow cytometer. The four fluorescent dyes are FITC,PE, PE-TR,and PE-Cy5. Their emisison spectra are provided below. Detectors are arranged as shown in thefigure below. The FITC signal is detected from Filter 1, the PE signal from Filter 2, the PE-TR signal fromFilter 3 and the PE-Cy 5 signal from Filter 4. Part 4.1Provide a rationale for the order in which the filters are arranged with respect to the unfiltered signal. Part 4.2You are given 9 candidates from which you have to choose 4 for the filters in the diagram above. Choose4 and justify your selection.# Filter type WavelengthA Long pass 650 nmB Short pass 530 nmC Long pass 490 nmD Band pass 550-590 nmE Long pass 560 nmF Short pass 640 nmG Long pass 620 nmH Band pass 620-640 nmI Short pass 590 nmarrow_forwardPond B Pond C Figure 3. Representation of three experimental ponds located in the Hagen Aqualab at the University of Guelph. Ponds have one or both of two fish species: Stripey- Orange Clownfish and Black Herring. All ponds have been kept at 20°C for many years and contain large and small worms as food. For each statement, select TRUE if it is consistent, or FALSE if it is not consistent with the information presented above. True Felco If we add 3 Black Herring to Pond A and over time the number of Black Herring returns to 2, then the carrying capacity of Black Herring in Pond A is 5.arrow_forward
