Facilitated diffusion is the diffusion of solutes through transport proteins in the plasma membrane. Facilitated diffusion is a type of passive transport. Even though facilitated diffusion involves transport proteins, it is still passive transport because the solute is moving down the concentration gradient.
Explanation:
Fossil fuels are important energy sources for our every day activities.
Formation of fossil fuels
Fossil fuels forms from the accumulation and burial of organisms in a basin of deposition. Instead of the organisms decaying, they preserve their carbon content. To be worthy of becoming fossil fuels, organisms must be buried in an environment where there is little to no oxygen to fast-track decomposition of the buried organic matter. Increase in temperature and pressure causes the organic matter to transform into fossil fuels.
How are they obtained
First, different fossil fuels have their extraction techniques because they occur in different physical state of matter.
For the solids e.g coal: exploration is carried out first and if a prospect is delineated, mining engineers design the best way to extract the coal from nature. Coal is usually found laid in sedimentary beds in nature. Top layers of sediments can be removed to extract the coal.
For fluids such as crude oil and natural gas, after a prospect is identified, a rig is usually constructed to extract the fluid and gas. The natural pressure allows for the fluids the rise within the drill used in extraction.
How are they used
Coal and gas are used to power electrical generating plants. They are used to heat steams which drives turbines and produce electricity.
Natural gas is used as a domestic fuel for cooking and so also coal.
When crude is processed a lot of product is obtained. Gasoline is used to power most internal combustion engines. Some chemicals useful for manufacturing plastics, drugs e.t.c are also derived from the processed crude.

Atherosclerosis
is a condition that occurs when fatty substances (plaque) build up in blood
vessels. The
accumulation of the fatty substances can cause partial or complete blockage of
blood flow through an artery. Symptoms of this condition include a mini-stroke, pain
in the chest <span>and pain in the leg muscles during exercise.</span>
39%. Adenine would have the same percentage as Thymine, meaning it would he 32% A and T and then subtract that from 100 giving you 72 divide that by 2 and you get part Guanine and part Cytosine.
Well... I get the felling I know what question you are trying to ask. Atrial Fibrillation is a type of arrhythmia that interferes with the pumping of blood through the Atrium of the heart. A bundle branch block is an interference of the electrical system through the heart. Non of these are particularly that dangerousso don't worry about dying... Though have someone close by in case you go into Cardiac Arrest.
If your worried about getting a heart attack, that is a blood flow problem which can result from CAD. Don't worry though cause the two other condition do not particularly influence the other.
CAD is circulatory, A fib and branch block are electrical.
