bilayer and proteins exist side by side without covalent bonds between them. The membrane interior appears granular on an electron micrograph. Integral membrane proteins span the membrane. Some proteins and lipids undergo lateral diffusion along the inner or outer surface of the membrane. Carbohydrates are covalently bonded to the outside of the membrane. None of the Above

The correct answers are: The lipid bilayer and proteins exist side by side without covalent bonds between them and  Some proteins and lipids undergo lateral diffusion along the inner or outer surface of the membrane

According to fluid mosaic model, there is a lipid bilayer that gives fluidity and in which the protein molecules are embedded.  

The membrane is mosaic because there is a pattern of different types of molecules that are put together. Molecules are constantly moving in two dimensions.

Components of the cell membrane include:

• Phospholipids – Form a bilayer  

• Cholesterol –improves stability and reduce fluidity

• Proteins –integral (transmembrane) or peripheral  

• Sugars-usually attached to proteins.

2. Explain why people with poorly controlled diabetes are at risk for amputation
mestny [16]
People with poorly controlled diabetes are at risk of amputation due to damage of nerves in the extremities of the body. This damage to nerves is caused by chronically  high blood sugar. The condition, when it is caused by uncontrolled blood sugar is called diabetic neuropathy.<span>Diabetic neuropathy mostly affects the feet and they lose feeling, such that an affected person cannot  sense pain. When they develop an ulcer or small injury to the feet, it may often go unnoticed and with time become infected.  High blood sugar impairs  the normal healing process and the injury or ulcer may not heal quickly thus compounding the problem. The outcome of this is that the infected part e.g. a toe, may fester and even become gangrenous putting the whole bod at risk and thus the only away to save the rest of the body is removal by amputation.</span>

A population of ground squirrels lives in underground burrows several miles from an ocean shore. If a hurricane strikes the shor
Travka [436]

Answer:

flooding

Explanation:

The hurricane brings in enormous amounts of rainfall with it, often resulting in flooding. The ground squirrels in this scenario live relatively close to the ocean shore. They live in burrows, spending big portion of their time in them, as well as having their young ones sheltered in them. The heavy rainfall and the flooding of the area will result in filling the burrows with water. The damage for the population of ground squirrels will be enormous, with their young ones all drowning for sure, and the majority of the adults getting drowned as well, or maybe even all of them. Hope this helps!!!!!
