<span>The part of the ear where sound wave compressions and
rarefactions cause the eardrum to vibrate is the middle ear. The 8th
nerve in the inner ear actually converts the mechanical energy to electrical
energy for transmitting to the brain. A membrane called the tympanic membrane
separates the middle ear from the outer ear. Whenever a sound reaches the ear,
it creates a sound wave that creates vibration in the eardrum. The pressure
when high pushes the membrane inwards while low pressure sound waves helps the
eardrum to come outwards. </span>
the answer is a because if the model is based on experimental data it wont be good unless it has been tested.
Answer:
Part A It is associated with peroxisomes and mitochondria.
Part B. It is associated with smooth endoplasmatic reticulum.
Explanation:
The oxidation of long chain fatty acids are produced at the beginning in the mitochondria, it is called B oxidation because there is a carbon in this position that in this process is going to be oxidized to a carbonyl group. The very long fatty acid chains are also oxidized in the peroxisomes.
The cholesterol biosynthesis is made inside the hepatic cells, in the endoplasmatic reticulum. Is a process that starts with acetyl Coenzime A that was oxidized in the mitochondria. This process is regulated by the intake of cholesterol from the diet.
Hope this info is useful.
