Answer:
c. facilitated diffusion requires an integral protein
Explanation:
Facilitated diffusion is process of the spontaneous passive transport (high to low concentration) of molecules or the ions across biological membrane by using specific trans-membrane proteins.
Facilitated transport does not require chemical energy from the ATP hydrolysis as it is a passive transport.
On the other hand, simple diffusion is the transport of the molecule from high tot low concentration without the use of a specific molecule.
Option A, B, D and E are incorrect.
Answer:
<u>That's not actually accurate!</u>

Although not taking the full regimen may reduce the effectiveness of chemical combination that is supposed to kill the bacteria <em>not</em> "cause more problems", In general, antibiotics have proven to be helpful for maintaining a healthy/comfortable body.

Can you ask your question a little more clearly please?
Answer:
c. The abnormality is in the thyroid gland itself.
Explanation:
Primary hypothyroidism arises from a pathology in the thyroid gland itself and occurs when the thyroid gland is not able to perform one of its many physiology. Secondary hypothyroidism starts at the level of the pituitary gland and results from under secretion of TSH. TSH is needed to trigger the release of the T3 and T4 stored in the thyroid gland. Tertiary hypothyroidism is caused by a decrease level of the TRH from the hypothalamus. This reduced level, in turn, reduces TSH and thyroid hormone levels in the blood, hence in the body and the patient suffer the symptoms.
