<h2>Cell Locomotion</h2>

Explanation:

The correct order of  events in cell locomotion are:

2. A part of the cell surface protrudes in the direction of cell movement.

3. Lower surface of cell protrusion attaches to substratum, forming temporary anchorage sites

4. The bulk of the cell is pulled forward over adhesive contacts.

1. The cell breaks its rear contacts with the substratum, retracting its trailing edge.

Animal cell move by crawling. It is  a three step process that involves protrusion of the cell surface that attaches to the substratum, extrusion and retraction.

A mitochondrion has just been engulfed by a cup-shaped isolation membrane as it undergoes mitophagy. Before lysosomal fusion, ho
harkovskaia [24]

Answer:

Option-C

Explanation:

Mitophagy refers to the process which is evolutionarily conserved in the organisms to remove the dysfunctional mitochondria in the cell.

The mitochondrial is degraded by the digestive organelles by engulfing the mitochondria.

The mitochondria are engulfed by the lysosome and then phagosome is formed which is double membrane structure. This phagosome matures into the autophagosome and now has the mitochondria engulfed.

Since the mitochondria contain toe layer and during mitophagy engulfed by the phagosome, therefore, there is a total of four-layer.These four layers separate the matric of the mitochondria with the cytosol.

Thus, Option-C is the correct answer.
