Using the ultrasonication and agitation method of liposome preparation, what concentration of lipid is necessary to prepare lipo
Galina-37 [17]

The concentration of lipids necessary to prepare liposomes with a diameter of 250 nm is 0.30 mM.

<h3>What are liposomes?</h3>

Liposomes are vesicles which are made up of a lipid bilayer membrane.

Liposomes are important as delivery vehicles for substances such as drugs.

Ultrasonication is a method of liposomes preparation.

Solution of liposomes is dependent on the size.

The larger the diameter, the smaller the l elution volume. Also, increasing lipid concentration will decreases elution volume.

Therefore, the concentration of lipids necessary to prepare liposomes with a diameter of 250 nm is 0.30 mM.

enzymes degrade proteins, lipids, and large carbohydrates to smaller building blocks in the digestive tract. why must these macr
Rom4ik [11]

Amino acids, which serve as the "building blocks" of proteins, are disassembled. These tiny molecules can be absorbed through the stomach wall after being released.

<h3>Describe how the macronutrients in your diet are digested and then put back together to form the cell structure.</h3>

The principal macromolecules, from which all life is derived, are macrounits in our diet. The smaller subunits of these macromolecules must be broken down in order to be released. The circulatory system carries the digestively released components to the body's cells. These subunits serve as the building blocks for the macromolecules required for cellular structure and function, which are then put together by cells.

Proteins, lipids, and carbohydrates are examples of macromolecules.

The fact that all three macromolecules are hydrocarbons means that the majority of their atoms are made up of hydrogen and carbon.

Nitrogen atoms are found in proteins and in lipids.

Carbon atoms make up carbohydrates.

Simple carbohydrates are formed when complex carbohydrates are hydrated (by adding hydrogen and oxygen ions).

Dehydration of simple carbohydrates causes them to bind together in chains to create complex carbs. This can be reversed.

What's the eruptive style of composite volcano?
DerKrebs [107]

Answer:

Composite volcanoes are tall, steep cones that produce explosive eruptions.

Shield volcanoes form very large, gently sloped mounds from effusive eruptions.

Cinder cones are the smallest volcanoes and result from an accumulation of many small fragments of ejected material.

Cloud [144]

Structural adaptations are biological characters of an organism like the bill on a bird or the fur on a bear. Other adaptations are behaviour.

<h3>Define adaptation?</h3>

Adaptation, the method by which a species becomes adapted to its surroundings; it is the outcome of biological selection's acting upon heritable divergence over various generations.

Thus,Structural adaptations are biological characters of an organism like the bill on a bird or the fur on a bear.
