Answer:
1. The objective lenses on a compound light microscope sample can be magnified either, 40x, 100x or 400x as it does have powers 4x, 10x, and 40x on the maximum power setting.
At 40x magnification Stella will see cell upto 5mm.
At 100x magnification Stella will be able to see cell and cell components upto 2mm.
At 400x magnification Stella will be able to see cell and cell structures more closely, 0.45mm, or 450 microns.
2. The white blood cells are stained here in purple and can be identified with their shape and size of nucleus in comparison to the red blood cells have bioconcave shape and smaller to the wbc, but the function of white blood cells does not allow them to have a set shape. And the white transparent part are platelets.
Normally subcutaneous or injections just below the skin, may be at a 45 degree angle. However this is more dependent on the length of the needle, as depending on the length the injection may become Intramuscular or injections into the muscle.
Answer:
D: two jaguars per thousand hectares.
Explanation:
Population density refers to the computation of population by unit area. It is usually implemented in living organisms, generally in humans. It is a key geological term. In easy form, population density implies to the number of people existing in an area per square kilometer or hectare, etc.
So, two jaguars per thousand hectares is an example of population density as it involves the number of jaguars (population) per thousand hectares (per unit area).
