The total magnification would be 600x as you would obtain the total magnification by multiplying the objective lens magnification and the eyepiece magnification together.
40 • 15 = 600.
Vegetative Reproduction????
Answer:
oxygen: it was the result of biological activities. There were such stable continental shelf environments, which were rare in the Archean, developed after 2.5 billion years ago, facilitating the growth of photosynthetic organisms and thus oxygen production.
Exponential growth then logistic growth as it levels off due to carrying capacity
Note each of them:
Archaea is a single-celled microorganism with no nucleus
Bacteria is a unicellular microorganism with cell walls but lack organelles
Sarcodina is a phylum with temporary extensions of the cell. They can be parasitic.
Protista is an eukaryotic organisms that is not an animal, plant, or fungus.
The organism found is unicellular (rules out Archaea), with cell walls (characteristics of bacteria), and the ability to produce spores.
I believe that Bacteria (B) is your best answer
hope this helps
