The microscope is an instrument used for the visualization of the cell and its other component. Different types of microscope are compound microscope, electron microscope and binocular microscope.
The adjustment of the slide is important to visualize the focused object. A proper source of light is required to focus the image. At high magnification, the fine focus control is used for the adjustment. At 100 X the oil is used to visualize the object.

True
Explanation:
Geneticists have discovered that all human embryos start life as females. In the early development in the embryonic stage, this is true both for humans and mammals. This changes only at the 2nd month (in the case of humans, since different mammals have different gestating periods) if the embryo can elaborate enough androgens (dominant male hormone) to offset the maternal estrogens (dominant female hormone) then, maleness develops.
It is important that it has half because there is a half that comes from each parent. so to equal it all out human gametes have a half set of dna instead of a full set
In practice it is enough to simply angle the thermometer towards the direction of the ear canal. More specifically you are trying to target the direction of the tympanic membrane located in the middle ear (one of the parts of the ear; the other parts being outer and inner)
Some maneuvers, although not completely necessary, may include pulling the ear lobe upwards and outwards for babies. This is to straighten the ear canal and is more often done when using otoscopes. For adults, we pull the ear downward and outward.
