Answer:
Option (1).
Explanation:
Biological membrane mainly composed of lipids and proteins with the small amount of carbohydrate exposed on the outer surface of the membrane. This membrane plays an important role as it separates the cellular environment and facilitate the transport of the selected molecule.
The flippase enzyme is required to transport the molecules from one side of the membrane to the other membrane. Lipids and proteins can undergo lateral motion but at the different rate within the membrane.
Thus, the correct answer is option (1).

Answer:
Explanation:
Since it has been observed that Salmon runs from the ocean to freshwater is a very important process.
It has been highlighted from careful observation that Salmons carry nutrients from the ocean to the fresh water environment. We can propose that since the ocean is a vast sea of dissolved salts, moving Salmons would carry some of the dissolved salts in their tissue and body parts towards the freshwater.
As the salt gets into the fresh water, a natural balance is created as animals such as bears and birds consume them, they distribute the salt to other parts of the ecosystems through their activities.
With the introduction of large scale industrial fishing by man, the balance is tipped. The salt is now held up in human body systems and some salmon are used industrially. This deprives plants and animals that relies on this nutrient source for making the most of them. Deficiencies of the salt can lead to serious diseases in other parts of the ecosystem.
