Answer:
The correct word to be fill in the blank is 'energy.'
Explanation:
Secondary active transport is a type of active transport, which involves transport of molecules or ions across the membrane against their concentration gradient by using energy.
In secondary active transport, energy is provided by electrochemical gradient. It involves transport of two molecules or ions (either in same or opposite direction) and required energy is generated due to difference in electrochemical gradient formed by pumping or ions across the cells.
An example of secondary transport is transport of potassium ions by K+/H+ exchanger that transports hydrogen ions and potassium ions in opposite direction. It uses energy from proton motive force (generated by transport of hydrogen ions or protons) to transport potassium ions.
Thus, the correct answer is 'energy.'
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.
Answer:
<h3>
the lacrimal gland</h3>
Explanation:
<em>It is secreted by the </em><em>lacrimal gland</em><em> on the underside of the upper eyelid. In addition, mucus mucin (secretory mucin), which is secreted by the goblet cells on the surface of the eye, helps distribute tears across the surface of the eye uniformly</em>
Answer:
The answer is A intestinal lining
Explanation:
Salmonella typhi is a bacterium that is located in the intestine of the host producing a diarrheal disease that can be acute or chronic, since at the level of the intestine it is usually where we will find it.
