Studies of the endomembrane system often involve the use of a protein that can emit a green fluorescence (glow). a researcher wants to make a video of cell behavior, so she initially tags the outer nuclear envelope of a cell with the fluorescent tag and records for several hours. later, she sees that the tag is part of a secretory vesicle.
the fluorescent tag likely became incorporated into which of the following organelles during the video?
a. endoplasmic reticulum.
b. ribosomes.
c. mitochondria.
d. peroxisomes.

The correct answer is A) endoplasmic reticulum.

Explanation:

The endomembrane system performs several functions, mainly transport to many destinations inside or outside the cell. Many studies have been made, where the transport chain can be seen, anyway, the endoplasmic reticulum (smooth and rough) is one vital part of this system.

a tetrad is the foursome during meiosis made by two homologous chromosomes that have each already replicated into a pair of sister chromatids.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
