<span>A scenario where a cell may be needed to perform a form of endocytosis is when transporting large molecules.
A scenario where a cell may be needed to perform a form of exocytosis is when releasing the large molecule from the cell. The movement of macromolecules of polysaccharides or proteins out of or into the cell is known as Bulk transport.
Bulk transport is of two types which include endocytosis and exocytosis whereby both require an expenditure of energy. Exocytosis materials are being exported out of the cell via secretory vesicles.
Golgi complex they do package macromolecules into transport vesicles which travel to and spill its content out of cells. Exocytosis is very much important in the expulsion of waste materials out of the cell and also in products secretion. Endocytosis is the process where materials move into the cell.
Endocytosis is divided into the three types which include pinocytosis, phagocytosis, and receptor-mediated endocytosis.</span>

angle of incoming sunlight
Explanation:
The single feature that primarily determines the variation in climate in different parts of the world is the angle of incoming sunlight.
- Climate is simply an extended study of weather over a long period of time.
- The elements of weather like temperature, pressure, rainfall all conditions climate.
- The angle of incoming sunlight is by far the most important factor that determines climatic patterns on the earth.
- Around the equator, the sun is overhead and these regions are usually hot driving a wide range of weather phenomenon.
- The polar and temperate regions receive diffused sunlight because the sun is at an angle there.

Answer:
True
Explanation:
Cell cycle checkpoints are an important layer of control of the cell cycle. The cell cycle is a process by which cells divide.
There are 4 stages of the cell cycle G1, G2, S and M.
When the cell goes through the cell cycle, each stage has different processes that must occur for the cell to properly divide. During G1, the cell must grow to sufficient size and the environment must be favorable for cell division. During S phase, all the DNA must be properly replicated. during G2 the cell must prepare for division. During M, the cell actually divides.
There are 3 checkpoints throughout the cell cycle. The G1 checkpoint ensures the cell has reached sufficient size. The G2 checkpoint ensures the DNA has been properly replicated. The M checkpoint makes sure the chromosomes are properly attached to the spindles to split the DNA between 2 new cells.
Without these checkpoints, the cell can divide uncontrollably which can lead to cancer.
