Answer:
Option-C
Explanation:
A pulse-chase experiment which is used to study the cellular process taking place in the cells. This uses the labelled molecule which is incorporated into the cellular pathway and then the unlabeled molecules are used over time to determine how much time is required by the unlabeled molecule to replace the labelled molecule.
In the given question, the pancreatic cell which secretes the digestive enzyme known as the acinar cell is labelled with the leucine and then used unlabeled leucine.
When observed after three hours, the black spots will appear on the exterior of the cell as the protein has been synthesised by the ER and now has been secreted from the cell.
Thus, Option-C is the correct answer.
one of the most important rain forest predators, attacking a wide range of different primates, is the monkey-eating eagle. we know this because all forest primates have an identical alarm call that means, essentially, "Eagle!"
<h3>What are primates?</h3>
Primates are those forest animals that has highly developed brain and backbone.
Some of them are predators while others are source of food for predators known as preys.
Example of such predators are the monkey eating eagles which are capable of hunting monkeys as their preys.

#SPJ1
Rough ER - protein synthesis, transport of proteins throughout the cell
Smooth ER - lipid synthesis and cell detoxification
Neuroglial Cells is the answer
This is possible by having different stem cells for different types of cells which then have different genes activated to make cells different
