The ability to internalize material from outside the cell is important for several cellular processes including the ingestion of essential nutrients, removal of dead or damaged cells from the body, and defense against microorganisms. <span>Eukaryotic cells </span>internalize fluid, large and small molecules, and even other cells from their surroundings by a process called endocytos<span>There are two main types of endocytosis that are distinguished by the size of the vesicle formed and the cellular machinery involved. Pinocytosis (cell drinking) describes the </span>internalization<span> of extracellular fluid and small </span><span>macromolecules </span><span>by means of small vesicles. </span><span>Phagocytosis </span>(cell eating) describes the ingestion of large particles such as cell debris and whole microorganisms by means of large vesicles. While all eukaryotic cells are continually ingesting fluid and molecules by pinocytosis, only specialized phagocytic cells ingest large particles.<span>
</span>is. During endocytosis, the plasma membrane of the cell forms a pocket around the material to be internalized. The pocket closes and then separates from the inside surface of the plasma membrane to form a membrane-enclosed bubble, or vesicle, containing the ingested material.

How have advances in biotechnology and genetic engineering been built on past discoveries?

uranmaximum [27]

<span>It began with selective breeding in the ancient times where a population with desirable traits were bred with other population to achieve a desired set of traits. It then continued with the advance in the discovery of bacteria (Escherichia coli) and antibiotics. Then Watson and Crick discovered the structure of DNA.

When you breathe, the pressure inside the lungs is different than the pressure outside the lungs. this is an example of a(n)?

goblinko [34]

The pressure inside your lungs and the pressure outside them fluctuate as you breathe. An illustration of a pressure gradient is this.

<h3>What is an example of pressure gradient?</h3>

The pressure gradient is the amount by which the atmospheric pressure drops in a location at a particular time.
A pressure gradient is demonstrated by gale-force winds in one city changing to a moderate breeze after an hour. the rate of the pressure in space decreasing (gradient) at a specific period.

<h3>How does pulmonary ventilation change with pressure gradient?</h3>

Thoracic ventilation Because air moves down a pressure gradient, or from an area of greater pressure to an area of lower pressure, the difference in pressures is what drives pulmonary ventilation.

When breathing in and out, the respiratory airways restrict the flow of air. The air must be transported by the pressure gradient from the mount (or nose) to the pulmonary alveoli.
