- What is the positive and negative result in Physical Growth Requirements, temperature, osmotic pressure and pH level. With a brief explanation.List five (5) factors affecting fixation of the cells in a physical and chemical stateFacultative means growth in presence and absence of oxygen. Select one: O True O False
- Provide the term or a sentence that best describes the information below: The process that is chiefly responsible for the maintenance of leaf temperature in a physiologically acceptable zone.A student studying aquaculture is interested in how diet and water temperature affect the growth rates of fish. She hypothesizes that fish receiving a high protein diets and in warmer temperatures will have enhanced growth rates. She has four treatment groups: Fish tanks in a laboratory at 22 degrees C and high protein diet. Fish tanks in a laboratory at 22 degrees C and low protein diet. Fish tanks outside with a temperature of 26 degrees C and high protein diet. Fish tanks outside with a temperature of 26 degrees C and low protein diet.
