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.

Organisms with advantageous adaptations are more likely to survive and reproduce than organisms without the advantageous adaptat
expeople1 [14]

Natural selection refers to the phenomenon by which the species in a population possessing the tendency to get adapted in a condition enhance in numbers in comparison to those who exhibit fewer adaptation capacities over a number of generations.  

In other words, it can be stated as the non-random and differential development of distinct genotypes function to sustain favorable variant and to eradicate less favorable variants. Some of the conditions are required for the process of natural selection to take place.  

These are heredity, reproduction, variation in individual characters, and variation in the fitness of organisms among the members of the population. If the conditions are met, then the phenomenon of natural selection occurs by default.

What is the number of paired processes in the thoracic bony vertebra?
anygoal [31]

Answer:

There are six facets per thoracic vertebrae: two on the transverse processes and four demifacets—the facets of the transverse processes articulate with the tubercle of the associated rib. The demifacets are bilaterally paired and located on the superior and inferior posterolateral aspects of the vertebrae.

If the dna of a certain organism has guanine as 30% of its bases, then what percentage of its bases are adenine?
serious [3.7K]
G always pairs with C...So, if there is 30% G, then there's 30% C...which is 60%...that leaves 40% A+T - and you have to split this up too - so 20% Thymine (T) and 20% Adenine (A).
