The sled with a rough metal bottom would take more force to move over ice, because the rough surface would increase friction and the force needed.
Quantum Physics help us understand the properties of solids, atoms, nuclei, sub-nuclear particles and light.
The word quantum refers to discreteness.
-Photosynthesis occurs in the chloroplast, an organelle specific to plant cells. The light reactions of photosynthesis occur in the thylakoid membranes of the chloroplast.
-Energy Cycle in Living Things
The chloroplasts collect energy from the sun and use carbon dioxide and water in the process called photosynthesis to produce sugars. Animals can make use of the sugars provided by the plants in their own cellular energy factories, the mitochondria.
-Cyanobacteria, often known as blue-green algae, are among the most abundant organisms in oceans and fresh water. They are similar to green plants because they can use the energy from sunlight to make their own food through photosynthesis.
-What is a microbe? A microbe is any living organism that spends its life at a size too tiny to be seen with the naked eye. Microbes include bacteria and archaebacteria, protists, some fungi and even some very tiny animals that are too small to be seen without the aid of a microscope.
-Plants, algae and cyanobacteria use a chemical reaction known as photosynthesis to create the materials they need from what's around them. Plucking carbon dioxide from the air, water from the ground and light from the sun, land plants make sugar and kick out oxygen as a waste product.
