Scientists could use radioisotopes to study the function of the Golgi apparatus by tracking the radiolabelled sugars along with proteins in the Golgi apparatus.
Radioisotopes of radiolabelled sugars are attached to proteins within the Golgi apparatus and are used for purpose of function study and are found in eukaryotes which is a membrane-bound organelle. It is made up of cisternae in flattened, stacked pouches. Proteins and lipids are moved, altered, and packaged into vesicles by the Golgi apparatus and delivered to various locations. It is situated near the cell nucleus and the endoplasmic reticulum present in the cytoplasm.
In an experiment to determine the route secreted proteins follow, radioactively labeled amino acids are added to a culture of cells involved in protein synthesis which is in a growing stage. The secretory vesicles have radiolabeled proteins received from the Golgi apparatus, which are joined with the plasma membrane to release outside the cell.

A train traveled at 350 km in 2.5 hours. What was the average speed of the train?
Answer:
140 km per hour.
Explanation:
350 divided by 2.5= 140
The average speed of the train was 140 kilometers per hour.
Speed is a unit used to describe how fast something is moving with respect to another object. Due to its scalar nature, it has only magnitude and no direction. By dividing the distance traveled by an object by the time required to cover that distance, one can calculate its speed.
The formula for calculating speed is as follows:
Speed = Distance / Time
In the International System of Units (SI), the meter per second (m/s) is the accepted unit for measuring speed. Nevertheless, other common units for speed include kilometers per hour (km/h) and miles per hour (mph), depending on the situation and location.
We can use the following calculation to determine the typical speed of a train:
Average speed = Distance traveled / Time taken
In this example, the train covered this distance of 350 km in 2.5 hours.
Average speed = 350 km / 2.5 hours
Average speed = 140 km/h
Therefore, the average speed of the train was 140 kilometers per hour.

Pores on the skin surface open into the sebaceous glands.
The mid-dermis is home to sebaceous glands, which almost always develop alongside hair follicles and have an outlet that empties into the follicular canal. The pilosebaceous unit is the name given to this grouping.
The follicle also houses an oil gland and a hair (sebaceous gland). The oil gland keeps the skin lubricated, helps remove dead skin cells, and keeps tissues from drying out. Meibomian glands, a small group of sebaceous glands that open directly onto the skin in the epithelium of the eyelid, help to improve the lubricating abilities of tears.
Function :
The sebaceous gland contributes the vast majority of skin surface lipids via its main product, sebum, which helps to seal in moisture and prevent desiccation of the skin. Because sebaceous glands empty into the hair canal, sebum mostly escapes onto the skin surface via a wicking action involving the hair shaft.
