Two students were testing the amount of fertilizer that would best promote the growth of strawberries in a garden. Which of the following could be an unavoidable source of experimental error? - Variation in the strawberry plants Both petri dishes with a dilute solution of iodine to indicate the presence of starch. The surface of petri dish 1 turned completely blue, indicating starch. Most of the surface of petri dish 2 was blue, except the letter was clear. The most probable explanation...

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 ...

This document covers the two last assignments of unit 6 of BTEC Applied Science. DISTINCTION as well.

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...

lab 1: What did caffeine and ethanol do to the heart rate of the Daphnia? correct answers Caffeine speeds up the heart rate and alcohol slows it down lab 1: know independent vs dependent variable correct answers independent- one or more factors that the scientist varies during the experiment dependent- measured in order to determine if it changes in response to the independent variable lab 1: mean, median, mode, range correct answers mean- average, median- number in the middle, mode- occu...
