 <span>If not broken, the skin is an impenetrable barrier to viruses and bacteria. It is reinforced by chemical defenses. Oil and sweat give the skin a pH of 3-5. Bacteria that live on the skin help by releasing acids and wastes to kill off unwanted microorganisms. Lysozyme is found in tears and saliva which can destroy the cell walls of most bacteria. Gastric juices kill off bacteria in food. Mucus captures bacteria in the nose and throat cavities of the body. </span>

nignag [31]

The answer is ATP production glycolysis, Krebs cycle, and electron transport aerobic in that order. Glycolysis occurs in the cytoplasm while the other two stages occur in the mitochondria (Krebs cycle in the mitochondrial matrix and the electron transport chain in the mitochondria membrane).



The answer is Autotrophs. Examples of autotrophs are plants and photosynthetic bacteria (photoautotrophs). They convert abiotic factors such as light to organic molecules. These also include chemosynthetic bacteria (chemoautotrophs) that elements such as sulfur dioxide and methane in hydrothermal vents to organic molecules.
