Chylomicrons are essential for transporting dietary lipids, such as triglycerides and cholesterol, from the intestines into the bloodstream. Formed in the intestinal mucosa, they encapsulate lipids in a protein and phospholipid shell, allowing these hydrophobic molecules to travel through the aqueous environment of the blood. Once in circulation, chylomicrons deliver lipids to tissues for energy use or storage, facilitating lipid metabolism and nutrient distribution throughout the body. Without chylomicrons, the absorption and transport of dietary fats would be significantly impaired.

Short-chain and medium-chain fatty acids are lipids that can be absorbed directly into the bloodstream. Unlike long-chain fatty acids, which require emulsification and transport via chylomicrons through the lymphatic system, short- and medium-chain fatty acids are more water-soluble and can pass directly into the portal circulation. Additionally, some glycerol and certain other small lipid molecules can also be absorbed directly into the bloodstream.
no, it is not necessary but in future if you want to do mba then it will come in use
is not always directly involved as the transporting medium in mass movement processes, it does play an important role
A delta is a triangular deposit of sediment at the end of a river or stream. It happens when the strong current of the river slows down and deposits the sediments it has been transporting.
Stream velocity has a direct impact on the size of sediments that can be transported. Higher stream velocities can carry larger and heavier sediments due to increased erosive forces, while slower velocities are limited to transporting smaller and lighter sediments. This relationship is known as Hjulstrom's curve.
It depends on the flow rate of the stream. Typically, thousands of drops per second are needed to form a continuous stream visibly.
Stratification as this is a term that describes the layering of rocks and so is not a term that is related to sediment transport (i.e. erosion) but is instead the result of deposition, compaction and cementation.
The ability of a stream to erode and transport materials largely depends on its velocity and discharge. Higher flow velocity increases the stream's energy, allowing it to erode the riverbed and banks more effectively while transporting larger sediment particles. Additionally, the gradient of the streambed and the size, shape, and composition of the sediment also play significant roles in determining the stream's erosive and transport capacity.
Triglyceride levels vary by age, weight, and sex. Triglycerides are lipids that circulate in the blood stream. Measurements are usually taken when cholesterol levels are analyzed.
The slowest stream velocity necessary for a stream to carry small boulders typically ranges from 1 to 2 meters per second, depending on factors like the size and shape of the boulders, as well as the water's viscosity and density. This velocity allows the water to exert enough force to overcome the boulders' weight and drag. Additionally, streambed composition and gradient can also influence the required velocity.
