How does the relationship between salt concentration effect osmosis in the aquatic plant Elodea? Quantitative data From observing the cells under a microscope‚ we see that they are continuously moving and therefore are alive. We have observed that when the cells are in the 10% sodium chloride‚ the chloroplasts are positioned to the sides of the cell wall and the cytoplasm is more expanded. Cells in the distilled water are slightly smaller than the cells in the sodium chloride solution and

separated into two categories prokaryotes and eukaryotes. Prokaryotes are typically found in unicellular organisms. They do not have a nucleus or nucleus bound organelles. Therefore their DNA‚ proteins‚ ribosomes and etc. are enclosed within the cell membrane‚ without any specific location. They reproduce by the process of binary fission. The two domains of organisms that contain these cells are bacteria and archae. Archae is a unicellular organism that grows in extreme environmental conditions‚ it is

exercise – Bones & Joints. • We produce more synovial fluid – Movement stimulates the secretion of synovial fluid. • The joints become warmer – Exercise increases the bodies temperature – The synovial fluid becomes thinner‚ making movement more efficient. • The range of movement increases – Due to the fact that the synovial fluid is thinner and warmer • All of this is because exercise makes our joints move quickly‚ so there needs to be more synovial fluid in the joints to allow and assist this

Describe the basic anatomy of the human body affected by assisting and moving The human body is only able to assume it’s different posture and maintain its structure due to the skeletal system. The skeletal system is made up of bones which have an outer hard cortical layer and an inner soft trabecular layer made of cancellous bone. Within some long bone is the all important marrow from where all the blood cells originate after maturation. The skeletal system can be divided into 2 groups: 1.

This is because lipids help the body function by storing energy and nutrients‚ structural components of the cell membrane. Proteins help structure and function throughout the body‚ and the nucleic acids is the gene that carries genetic information and forms structure within the cells. B. Dehydration synthesis and Hydrolysis are the opposite of each other. Dehydration
