Scientists can track the movement of proteins through the endomembrane system using an approach known as a pulse-chase experimen

t. This experiment involves the "pulse" phase: cells are exposed to a high concentration of a radioactively labeled amino acid for a short period to tag proteins that are being synthesized. The "chase" phase: an unincorporated radioactively labeled amino acids are washed away and large amounts of the same, but unlabeled, amino acid are added. Only those proteins synthesized during the brief pulse phase are radioactively tagged. These tagged proteins can be tracked through the chase period to determine their location in the cell. The data below were obtained from a pulse-chase experiment in which cells were examined at different times during the chase period. The numbers represent the radioactivity (measured in counts per minute) recorded at each of the indicated sites. The higher the number, the greater the radioactivity.

Based on these data the most likely function of the cells is phagocytosis.

We can conclude this because, within the first three minutes, the radioactivity is the highest inside the ER. After that, it increases in Golgi apparatus, lysosomes and extracellular space which is exactly the pathway of the ingested amino acids via phagocytosis.

ELEN [110]
I believe the most appropriate is a selective medium and differential medium. Selective medium types are formulated to support the growth of one group of organism, but inhibit the growth of another. Blood agar is a differential medium that distinguishes bacterial species by their ability to break down the red blood cells included in the media. Blood agar is often used to distinguish between the different species of pathogenic streptococcus bacteria.

In a a person is assigned a status at birth and remains at that level throughout life.
alex41 [277]

Answer:

When a person is assigned a status at birth and must remain in it throughout his or her life, it is a caste system.

Explanation:

A caste system is applied in some societies and consists of the assignment of an individual to a social stratum by birthright, being forced to remain in that status and even relate to people of the same social category and allow endogamy.

It is a system that exists in ancient societies, an example being the Hindu caste system or South African apartheid. Other cultures that made use of the caste system were the Arab and Hebrew.

Unlike the caste system, the class system consists of inclusion in a specific social class, without the intervention of the birthright.

you are given two nucleic acids; one rna and the other dna. what are the main features to determine which is the dna?
BigorU [14]

Answer:

DNA is a long polymer with a phosphate backbone and deoxyriboses. Adenine, guanine, cytosine, and thymine are the four nitrogenous bases. The backbone of RNA is made up of ribose and phosphate. Adenine, guanine, cytosine, and uracil are four nitrogenous bases.

So DNA is two stranded, RNA is single stranded.
