D Aisha wants to conduct an experiment to determine whether sun and shade varieties of the same plant species prefer the same wavelengths of light. She plans to measure rates of photosynthesis. Which design would be best for her experiment? A.1 plant of the sun variety tested under blue light only, and 1 plant of the shade variety tested under blue light only. B.4 plants of the sun variety: 1 tested under blue light, 1 under green, 1 under red, and 1 under yellow light, and 4 plants of the sh...

Population - Answer - a group of individuals from the same species that occupy an area of space at the same time - can produce viable offspring - uses the same resources and are affected by similar factors Ecology - Answer - the study of how organisms interact with their environment What is population ecology? - Answer - measures changes in population size, pop composition - identifies factors that cause changes in population - studies how and why a population changes over tiime -IMP ...

the document focuses on project implantation and review on the practical performed which was effects of caffeine concentration on the daphnia heart rate. The document contains hypothesis, methods for preliminary investigation and preliminary results. The document also has final methods and results with analysis and graph construction with error bars. The document also contains mean and standard deviation calculated from the data generated for all the different concentration of caffeine. the docu...

Daphnia - ANS-A small water flea, they are often used to test the effects of caffeine on the heart as their heart is easily visible.
