Endocytosis moves large and polar molecules, that are unable to pass through a cell's plasma membrane, from the outside of a cell to the inside of a cell. There are three types of endocytosis:
- Phagocytosis (cell eating)- the process by which a cell engulfs macromolecules.
- Pinocytosis (cell drinking)- the process by which small dissolved substances enter a cell. Small vesicles pinch off of the plasma membrane into the cell.
- Receptor-mediated endocytosis- the process by which a cell engulfs molecules specific to its receptor proteins. Molecules bind to specific receptor proteins in the receptor-coated pit. Basically, this type of endocytosis is the same as phagocytosis. The only difference is the molecule specificity, which is sensitive to the type of receptor proteins.

Types of bulk transport in cell?
Bulk transport is in 2 forms, exocytosis and endocytosis. Each of these 2 forms can then be sub divided into phagocytosis (movement of solids) and pinocytosis (movement of liquids) When bulk transport occurs, a phospholipid bilayer membrane merges with the cell membrane, and forces the contents of the vesicle in.out of the cell.
What is no net force between object and its surroundings?
If there is no net force acting on an object then the movement of the object doesn't change. If it is sitting still, then it remains sitting still. If it is moving, then it continues moving at the same speed in the same direction.
Can endocytosis and exocytosis occur with the same cell?
Yes. Because the budding of endocytosisbrings in various nutrients in the cell andexocytosis takes out the waste and hormones of the cell.
What is the direction of the net force acting on the object at position A?
The net force is zero.
What does the term net movement mean for biology?
The water is not moving equilibrium.
What is the net movement of electric charges in a single direction?
An Electric Current :)
What is it called when the movement of a substance into a cell by a vesicle?
endocytosis
Movement of large molecules by formation of a vesicle?
endocytosis
How is direction of acceleration related to direction of momentum?
It isn't. The direction of momentum is the same as the direction of the velocity - of the movement. The direction of acceleration, on the other hand, is the same as the direction of the net force that acts on an object - and this force can be in any direction.
Identify the terms endocytosis and exocytose and distinguish between them?
endocytosis is the movement of a substance into a cell by a vesicle. while the movement of a substance by a vesicle tot eh outside of a cell is called exocytosis
What is The net movement of electric charges is a single direction is called?
That is called an electrical current, or just a current.

What are Ekman transport?
its the net movement of water as a result of Ekman spiral; in the northen hemisphere, 90 degrees to the right of the wind direction; in the southern hemisphere 90 degrees to the left of the wind direction
In which direction does friction act compared o the direction of movement?
In the same direction as the movement
A cell conducts endocytosis by what?
Cells perform endocytosis through membrane movement. Endocytosis is a type of Bulk Transport, which involves the movement of larger particles (vesicles) through the membrane in and out. Endocytosis involves Phagocytosis or Pintocytosis. Phagocytosis: when cells engulf particles via pseudopodia ("false feet"), which is packaged in the membrane into an enclosed sac, and once inside the cell, it becomes a vacuole. Pintocytosis: when cells GULP extracellular fluids and makes them into vesicles. The fluids are unimportant but gulped anyway for the molecules within it.
An object acted upon by a net force will accelerate in the direction of that force?
Newton's Second Law of Motion ...im pretty sure lol xD hope I helped!
Which transport process is the main mechanism of the movement of most macromolecules by body cells?
receptor-mediated endocytosis
