Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell.
Polygenic traits are those traits that are controlled by more than one gene. Such traits may even be controlled by genes located on entirely different chromosomes. Human height, eye and hair color are examples of polygenic traits. Skin color is another polygenic trait for humans and a variety of other animals.
Answer:
1.8 pounds of Nitrogen per year; (based on 1000 square feet per application) for cool season grasses.
Explanation:
The above application shows an average of 0.9 pounds of inorganic and organic nitrogen per 1000 square feet per application . Therefore not more than 0.9 pounds of nitrogen will be needed per application.And for a whole year 1.8 pounds of Nitrogen per year will be needed.
This calculation was based on 1000 per square.But most lawn are not 1000 per square, therefore calculation can be done using the 1000 per squares as the reference point .
AMMONIA and its solutions, AMMONIUM NITRATE AND UREA (which is organic source)<u>are the sources of this Nitrogen</u>.
Urea is non -explosive in nature and solid. However, ammonia and ammonium Nitrate are both explosive.
Answer:
Cells of skin, for instance, have highest mitotic index.
Explanation:
Many cells are capable of dividing rapidly. <u>For example</u>, in plants, the cells near the root tip in the apical meristem divide rapidly to push through the soil because the root cap detects the gravity and direct rapid division and growth of cells near the tip.
If we take muscle, skin, kidney, and lung as examples that are given in real question, <u>skin cells have the highest mitotic index because they need to get replaced most frequently</u>.
