Answer: There are two categories of cross membrane transport, active and passive. While active transport requires energy, passive transport relies on concentration differences inside and outside of the membrane. With films that cover the outermost membrane of the fruit (the skin), this concentration gradient can be removed or slowed so membrane transport is also slowed and as a result, the fruit stays fresh longer. A good analogy for this is considering evaporation in an open jar on a hot day versus if there was a lid on the jar. Both jars would be in the same conditions, but the jar with the lid would retain more water.

How the respiratory membrane works. What cell types and what forces allow the diffusion of gases across the respiratory membrane?
Acc6ording to the question:
When we breath; there is air in and out though out from our lungs. How could it happen. Oxygen and carbon dioxide moves across the respiratory membrane. Normally the membrane separating air within the alveoli from the blood within pulmonary capillaries and consists of the alveolar wall, the capillary wall, and their basement membranes. Respiratory membrane is very thin, somehow its is approximate less than 0.5 mm. Explain?The respiratory membrane includes millions of alveoli with a surface area, the large respiratory surface area, combined with other factors, makes for efficient gas exchange to meet our metabolic needs.
Respiratory membrane allows gases to be exchanged between the pulmonary capillaries, or blood vessels, and the respiratory units of the lungs, which consist of bronchioles, alveolar ducts, atria and alveoli.
Since respiratory membrane is very thin,it consists of only two cells, one is the alveolar epithelial cell and the other is pulmonary capillary cell.Gas exchange occurs in the lungs between the air and our blood.

Projectile motion is the motion of an object in two dimensions. This means that if an object moves in both the horizontal and vertical directions at the same time, it is said to be exhibiting a projectile motion. In simple words, if an object tends to follow a curved or parabolic path of motion, projectile motion is said to be existing.

What element is group 5 period 7
Group 5 contains vanadium (V), niobium (Nb), tantalum (Ta) and dubnium (Db). This group lies in the d-block of the periodic table. The group itself has not acquired a trivial name; it belongs to the broader grouping of the transition metals.
The element in group 5, period 7 is Nihonium (Nh). It has the atomic number 113.
What is Nihonium?Nihonium (Nh) is a chemical element with the symbol Nh and atomic number 113. It is a synthetic element and was first synthesized in 2003 by a team of scientists at the RIKEN institute in Japan. Nihonium is a member of the group 5 elements, also known as the Nitrogen group, and is located in the 7th period of the periodic table.
It is a highly unstable element and has only been produced in very small quantities for scientific research. Due to its short half-life, it does not occur naturally on Earth. It is also known as Ununtrium.

Pepsin, a digestive enzyme that degrades proteins in the stomach, is synthesized as pepsinogen and converted to active pepsin in the stomach by the re
Digestive enzymes help to break down food in its simplest form. Pepsin is a digestive enzyme which leads to the degradation of proteins in the stomach. It is produced as pepsinogen and converted to active pepsin in the stomach by the removal of several amino acids.
What is pepsin?Pepsin is a digestive enzyme which is present mainly in the gastric juice in stomach and helps to breakdown protein into peptides.
This pepsin is present in the stomach in the form of inactive pepsinogen. This pepsinogen gets active in the stomach by the action of hydrochloric acid.
Pepsinogen gets active and forms pepsin.
Thus, it can be concluded that the digestive enzyme pepsin degrades protein in stomach and is synthesized as pepsinogen and gets converted into active pepsin in stomach by removal of several amino acids.

What are the starting compounds in the process of cellular respiration?
Answer:
Sugar and oxygen
Explanation:
The chemical equation for cellular respiration is: C6H12O6+602 yields 6CO2+6H2O+Energy (Sugar plus oxygen yields carbon dioxide plus water plus energy). Not to be confused with photosynthesis, which is the exact opposite (Energy+6H2O+6CO2 yields C6H12O6+6O2) (Energy plus water plus carbon dioxide yields sugar plus oxygen).
