Nitrogen must be converted into nitrates before organisms can use it. If soil lacks nitrogen fixing bacteria, then it has few nitrates for the plants to take in.
Answer:
Muscle cells, especially heart muscle cells and fat cells have the most mitochondria in the human body.
Explanation:
Mitochondria, the powerhouse of the cell is an organelle where cellular respiration occurs. They supply energy to the cells for their functioning. The number of mitochondria in a cell vary depending on the energy requirement of that cell.
Muscle cells are very active in our body and need energy for the movement. Heart muscle cells require a lot of energy to contract and pump blood through the circulatory system all the time. So they have a lot of mitochondria to produce a vast amount of energy they need.
Answer:
In which stage of mitosis is it? Metaphase
What are the structures visible in green and blue fluorescence? green show Microtubules and blue Chromosome.
Explanation:
The chromosomes align themselves along the equatorial plane of the spindle. They are suspended by microtubules.
Embryonic stem cells have the ability to become all types of cells.
That means that those stem cells can become kidney cells, lung cells etc.
If you nurture these stem cells with healty cells from a tissue or an organ, those stem cells will eventually grow into and become the same as the cells you nurtured the with.
This means that you could use embryonic stem cells to create healthy kidneys, skin and other types of tissues/organs.
Cell Membrane Semi-permeable membrane made of phospholipids that acts as a barrier between inside and outside of the cell.
Cytoplasm The fluid, cytoskeleton, and organelles inside a cell.
Nucleus Contains DNA and control's the cell's activity.
