Ascientist is interested in comparing the age of a rock with other rocks. by doing
this, the scientist is determining

The scientist is determining the relative age of the rock and the method is known as relative dating of rocks.

Explanation:

The relative dating method is based on the fact that more older the rock layers, the more it would be deeper. The overlying layer of rock will be located in less deeper location, henceforth it would be less older rock layer. This method is mainly used by the scientists, for determining the age of the rocks or fossils embedded in it, before any absolute dating method like radioisotope dating of rocks is discovered.

ysosomes are membrane-bound vesicles that contain digestive enzymes, such as glycosidases, proteases and sulfatases. lysosomal enzymes are synthesized in the endoplasmic reticulum (er), are transported to the golgi apparatus, and are tagged for lysosomes by the addition of mannose-6-phosphate label.

explanation:

humans, along with other animals and plants, have linear chromosomes that are arranged in pairs within the nucleus of the cell. the only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome.
