Answer:

Objective Lens Magnification = ×100

Explanation:

In a microscope, the ocular (eyepiece) lenses are usually to a magnification of ×10, meaning that it magnifies the image 10 times. While the standard objective lenses have magnifications of ×4, ×10, ×40, and ×100.

In order to work out the total magnification, the individual magnifications of the ocular and objective lenses have to be known, after which a simple multiplication of both magnifications will give the total magnification used.

Total Magnification = (eyepiece lens magnification) × (objective lens magnification)

1000 = 10 × obejcetive lens magnification

Dividing both sides by 10

Objective lens magnification = 1000 ÷ 10 = 10

∴ Objective lens magnification = ×100

hoa [83]

Matter can change from one state to another when thermal energy is absorbed or released. A great example is Ice having its state changed to the liquid that is WATER. When ice is heated, it absorbs thermal energy and its temperature rises. At some point, the temperature stops rising and the ice begins to change to water, a liquid. As we all know, The change from the solid state to the liquid state is called melting.

Nikolay [14]
In diseases, similar patterns of mutations in harmless genes may possibly be a cause or an effect of the disease. To investigate if it is a cause, it is worth looking into the proteins synthesized by the gene and whether it’s structure or functionality is affected by the pattern observed. It is also worth looking into the downstream effects possibly caused by the pattern in the gene. The gene may encode a non coding region which could affect post transcriptional splicing for example.
