For this experiment petri-dish A is fully exposed to the light source while petri-dish B is partially exposed to the light. Independent Variable: We have chosen our independent variable to be the amount of light exposed to the cress seeds. Our first petri-dish was allowed to be fully exposed to the light surrounding it‚ while the second was fully wrapped in black paper excluding a 0.5cm slit directed towards the sun. Dependent Variable: Our dependent variable is the reaction/actions to

1. The classification system developed by Linnaeus in the early 1700s divided living organisms into plant and animal kingdoms. Today‚ that has been expanded into five kingdoms. Which of the following inventions was most responsible for creating the need for the additional three kingdoms and why? (2 points) (0 pts) Fossil fuel-based transportation made it easier to explore and discover new species. (0 pts) Genetic engineering created new species which then needed new kingdoms.

Biomolecules Essay Before this year‚ I could never remember what DNA stood for‚ but now‚ not only do I know that it stands for Deoxyribonucleic Acid‚ I also know that there is another kind of nucleic acid called Ribonucleic Acid. RNA is an imitation for DNA‚ and like all imitations it is not a perfect replica so therefore it has small differences‚ and these small differences house the properties and opportunities for mutations and therefore it causes evolution‚ which allows us to adapt to our

Different methods of transpiration… Water uptake from the soil: Plant roots are surrounded by soil particles. The outmost layer of cells (the epidermis) contains root hair cells that increase the surface area of the root These cells absorb minerals from the soil by active transport using ATP for energy The minerals reduced the water potential of the cell cytoplasm; this makes the water potential in the cell lower than that in the soil. Movement across a root: The movement of water across the
