Answer:
C4 plants—including maize, sugarcane, and sorghum—avoid photorespiration by using another enzyme called PEP during the first step of carbon fixation. ... PEP fixes carbon dioxide into a four-carbon molecule, called malate, that is transported to the deeper bundle sheath cells that contain Rubisco.
Explanation:
Answer:
Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not.
Potassium-Argon dating has the advantage that the argon is an inert gas that does not react chemically and would not be expected to be included in the solidification of a rock, so any found inside a rock is very likely the result of radioactive decay of potassium. Since the argon will escape if the rock is melted, the dates obtained are to the last molten time for the rock. Since potassium is a constituent of many common minerals and occurs with a tiny fraction of radioactive potassium-40, it finds wide application in the dating of mineral deposits. The feldspars are the most abundant minerals on the Earth, and potassium is a constituent of orthoclase, one common form of feldspar.
Answer:
Most bacteria growth best within certain range of condition. By manipulating temperature and time, air, the proper amount of water acid and salt, you can eliminate, control, or reduce the rate at which bacteria grow.
Explanation:
Like all living things, bacteria need food, water and the proper environment to live and grow. The food product itself supplies the food and water needed for bacterial growth.he exact environmental requirements can vary from one type of bacteria to another. Most bacteria grow best within certain ranges of temperature, and have specific requirements related to their need for air, the proper amount of water, acid and salt. By controlling nutrients, water, temperature and time, air, acidity, and salt, you can eliminate, control, or reduce the rate at which bacteria grow.
Bacterias need following optimum conditions to grow
1. Food (nutrients)
2. Water (moisture)
3. Proper temperature
4. Time
5. Air, no air, minimal air
6. Proper acidity (pH)
7. Salt levels
By altering anyone of them we can restrict or reduce the rate at which the bacteria grow.
