The Cross-Linkage Theory or also referred to as the glycosylation theory of aging was discovered or proposed by Johan Bjorksten in the 1940s. According to this theory, the aggregation of cross-linked proteins can damage cells and tissues this slowing down the bodily processes that eventually results to aging. In recent studies, cross-linking is associated with age-related changes in the studied proteins. Furthermore, this theory stresses out that the binding of glucose to proteins can cause various problems. Once the said binding occurs, the protein becomes impaired which leads to its performance inefficiency. Living a longer life would also mean increasing the possibility of oxygen-glucose meeting and protein. Some of the known cross-linking disorders include senile cataract and the appearance of tough, leathery, yellow skin.
Answer:
b. Immnofluorescence
Explanation:
Immunofluorescence involves the reaction of a fluorescently labelled antibody to an expressed gene or protein making it specific. A microscope is used to locate the expressed gene via the fluorescent dye activated by light of a certain wavelength. It is usually done to analyze intact cells or tissue therefore it is easier to localize the gene expression.

Answer:
E) Scanning electron Microscopy
Explanation:
There are different types of microscopes and each one of then is suitable for a specific purpose.
For instance, the optimum method for a study that requires different cells to be examined and distinguished according to their size shape and 3D characteristic will be Scanning Electron microscopy
A Scanning Electron microscope will be used.
This type of microscope focuses beams of electrons on the surfaces of objects to produce images. From this image the shape , size and 3D characteristics of the cells can be distinguished
