The hydrophilic regions of phospholipids are positioned in the interior of the bilayer, while the hydrophobic regions are exposed to the cytosol and extracellular environment.
The hydrophilic regions of phospholipids are exposed to the cytosol and extracellular environment, while the hydrophobic regions are in the interior of the bilayer.

Answers

Answer 1

Answer: All plasma membrane surfaces are hydrophilic. In comparison, because of the fatty acid tails, the interior of the membrane between its two surfaces is a hydrophobic or nonpolar region. The main fabric of the membrane is composed of two layers of phospholipid molecules. The hydrophilic or "water-loving" areas of these molecules are in contact with the aqueous fluid both inside and outside the cell. Hydrophobic, or water-hating molecules, tend to be non-polar.

What are phospholipids?

Hydrophilic surfaces characterize all plasma membrane surfaces. In contrast, the inside of the membrane between its two sides is a hydrophobic or nonpolar region due to the fatty acid tails. The membrane's main fabric is made up of two layers of phospholipid molecules.

These molecules' hydrophilic or "water-loving" regions are in contact with the aqueous fluid both inside and outside the cell. Hydrophobic, or water-hating, compounds are typically non-polar.

Therefore, the correct option is d.

Neither the Secretary of the Interior, Congress, or any other branch of government, has the Constitutional power to disregard the Right of Occupancy and this fact is settled government policy. Congress has recognized Original Indian Title in several state enabling acts (or acts of Congress officially creating/recognizing a state) by requiring the incoming state to disclaim all right and title to lands owned or held by any Indian or Indian tribe. From our class discussion on Discovery, what the Treaty of Guadalupe Hidalgo transferred to the United States was the right to purchase/conquer the lands of that territory from tribes (the Federal Government cannot grant what it does not have). Where no land cession has been freely made by a tribe, Original Indian Title remains unaffected. So, the second right of Original Indian Title is to transfer that title to the sovereign possessing the right of Discovery. Title by conquest, or title obtained through military force, has, for the most part, not been asserted by the United States. There are two ways in which the United States could have acquired its territory, the only way used was that of voluntary cession through compensation (or, to put simply, purchase). To begin, reserve is defined as to refrain from using or disposing of (something); to retain for future use. Indian reservations did not describe land but were named for how the land came to exist as an Indian reservation. When the United States would attempt to purchase land of Native Americans, Indian reservations were created by removing those lands from the purchase so the tribe would continue to hold Original Indian Title within those boundaries. Original Indian Title contains two very basic rights, the right to occupy the lands involved and the right to sell those lands to the government who possesses the right of Discovery. Though the United States had the right to conquer Native American lands to claim possession, the fact is that the common approach was to avoid military conflict and to purchase those lands instead. Finally, Native American tribes would often reserve lands from those purchases, retaining the claim to Original Indian Title as far as Indian reservations were concerned. please help me write this story!!!!
