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.
Answer:
- The recoil force of a bazooka (reaction) + the accelerating force of a missile
- When walking, the foot pushes down and back (action) + the floor pushes up and forward
- When a rocket is taking off, the combustion of the fuels (an action) creates a direct and opposite reaction which is the thrust of the rocket upwards.
Explanation:
Newton's third law states that for every action (force) in nature there is an equal and opposite reaction. Simply put, forces act in approximately equal and opposite pairs (Action and Reaction).
This law is one of the reasons why the foundation of a building must be built in such as way that is exerting equal and opposite pressure against the building which it is carrying. When the forces are equal, the balance of forces are said to be in equilibrium.
