Major structural differences between a plant and an animal cell include: Plant cells have a cell wall, but animal cells do not. Cell walls provide support and give shape to plants. Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles if any are present.
independent= pH as you will change the pH in order to test your hypothesis and see if it's true
dependent= how amylase works-needs to be measured so you can see how easily it does it function depending on the pH (dependent on the independent variable)
Anything from virus vaccines, insecticide or even some of the food we eat (such as corn, soy beans, plums) have been Genetically modified with some sort of fish genes.
UV intensity predicts the skin color of indigenous populations. Stronger UV radiation is correlated with darker skin color. Data suggest that variation in human skin melanin production arose as different populations adapted biologically to different solar conditions around the world.
