Is walking on a treadmill good exercise for losing weight? I have changed my diet. I eat ALOT of salads and fish and chicken and I walk for 30 to 60 minutes on a treadmill several times a week. I have lost 5 pounds in about a week, but kind of stopped losing weight or at least have not noticed it as much. I also eat alot of fresh fruit. I was wondering if what i am doing is a good way to lose weight.
Many bacteria are motile and use flagella to swim through liquid environments. 2. The basal body of a bacterial flagellum functions as a rotary molecular motor, enabling the flagellum to rotate and propel the bacterium through the surrounding fluid. 3. Bacterial flagella appear in several arrangements, each unique to a particular organism.
what are cilia and flagella? Cilia and flagella are whip-like appendages of many living cells that are used to move fluid or to propel the cells. Cilia beat with an oar-like motion and flagella have a snake-like motion as illustrated in Figure 1. The cilia in your lungs keep dirt and dust from clogging your breathing tubes (the bronchi) by moving a layer of sticky mucous along to clean out the airways. Sperm cells use a flagellum as a propeller to move the cell through the fluid of the oviduct to reach the egg. Thousands of animals and plants use cilia and flagella for swimming (example: paramecium), or feeding (example: clams and mussels) or mating (example: green algae).
