From what I can see in the picture, the cell appears that it would take up half of the microscopes view if it were to be pushed to the very edge on one side.
That would be the radius. The radius is half of the diameter, and half of 0.8 mm would be 0.4 mm. The length of the cell is about 0.4 mm.
Now for the width. Since the diameter of the FoV (field of view) is 0.8, we can see that the cell doesn't reach both sides of the circle it is in. It also doesn't appear to take up half of it. So, to get the aprox. width of the cell, we're going to half the radius.
Half of 0.4 mm is 0.2 mm, so the width of your cell is about 0.2 mm.
Answer: Option A is correct. They eat consumers which ate plants, which absorb it from soil.
Explanation:
Carnivores get nitrogen from the food they eat or consuming nitrogen from the small insects trapped in plant. They eat consumers which in turn eat plants and absorb nitrogen from the soil.
Answer and Explanation: This is true that theories do change or get replaced overtime. We all know that in any scientific investigation the scientist put forth the theories which are basically the ideas explaining something particular. We also know that the world is experiencing constant changes and those changes could be of Technology or of overall world order so, whenever a scientist gives us the theory, that theory is made according to the situations and environment of that particular time and in future with the passage of time and with the advancement of Technology and other variables, scientist do need to re-evaluate theories. They either make some positive changes keeping in view the changing circumstances of the current situation or discard the theory altogether depending on its nature. The name research itself indicate that scientists research the already searched idea and in that way the New theory which comes after the modification of old theory or altogether the new theory takes place of the old one.
