Answer:

The blood in the pulmonary artery is going to the heart to collect oxygen, and therefore has a low content of oxygen. So, the blood in the pulmonary artery is a violet colour because it has low oxygen. The blood in the pulmonary vein is oxygen rich, and so it gives a scarlet color.

Adrenaline signaling occurs when the the hormones clings to the cell surface of the Adrenaline receptor.

The total modified protein target molecules resulting from a single activated signal receptor is 1,000,000 and this results in the consumption of 100 molecules of Guanosine triphosphate (GTP) and 1,010,000 molecules of Adenosine triphosphate (ATP).

Weight gain and depression are symptoms caused by imbalance of pituitary and adrenal glands and the cortisol hormone.

Explanation:

The pituitary gland is responsible for the overall functioning of the body since it produces a variety of hormones. It is very small in size and is also known as the 'master gland'. It is made of two parts- anterior pituitary gland and posterior pituitary gland. The pituitary gland and its functions are controlled by the hypothalamus.

The anterior pituitary secretes hormones which act on adrenal glands, thyroid, testes and ovaries. The hormones produced are TSH, Prolactin, Luitenizing Hormone, Cortisol, Testosterone, etc.

Cortisol is produced by the adrenal gland under the command of pituitary gland. Cortisol helps in regulating blood sugar, blood pressure and helps in reducing inflammation. Any imbalance of adrenal gland will cause an increase or decrease in the production of cortisol. The symptoms produced on the imbalance are:
