Answer:
I. Overall magnification (TM) = x40
II. Overall magnification (TM) = x100
III. Overall magnification (TM) = x400
IV. Overall magnification (TM) = x1000
Explanation:
A microscope can be defined as an optical device that is typically used to make an enlarged (magnified) image of a minute (small) object and as such reveals all the little information about the object that cannot be seen by the natural human eye.
Mathematically, the overall (total) magnification of a microscope is given by the formula;
Overall magnification (TM) = Eyepiece magnification(EM) X Objective magnification (OM).
I. When EM = x10 and OM = x4
TM = EM * OM
TM = x10 * x4
<em>TM = x40</em>
II. When EM = x10 and OM = x10
TM = EM * OM
TM = x10 * x10
<em>TM = x100</em>
III. When EM = x10 and OM = x40
TM = EM * OM
TM = x10 * x40
<em>TM = x400</em>
IV. When EM = x10 and OM = x100
TM = EM * OM
TM = x10 * x100
<em>TM = x1000</em>
Answer:
Las bacterias pueden utilizar la mayoría de los compuestos orgánicos y algunos inorgánicos como alimento, y algunos pueden sobrevivir a condiciones extremas.
Answer:
The correct option is C.
Explanation:
Evolution refers to the gradual development of living organisms from earlier forms to the forms that exist today. One of the principal factors that lead to evolution is the ability of an organism to adapt to adverse changes in its environment. Organisms that are able to survive adverse changes in their environments usually go on to produce offspring that possess their parents' ability to survive. A good example of this is given in option C, where individuals with denser fur were able to survive from severe cold and then give birth to young ones that inherit their parents' ability to survive severe cold.
The connective tissue layer surrounding bone is called the periosteum. It has an outer fibrous layer and an inner osteogenesic layer.
