Alexis is out mowing the lawn and starts to feel dehydrated. Her ______ will secrete vasopressin. A patient suffering from sever
adoni [48]

1. The right answer is - Hypothalamus (manufactured by the hypothalamus, stored in the pituitary gland).

Vasopressin, or antidiuretic hormone, is a peptide hormone synthesized by the supraoptic and paraventricular nuclei of the hypothalamus, and released by the posterior pituitary gland (neurohypophysis).

It mainly has an anti-diuretic role in the kidney, where it causes a reabsorption of water via an action on the distal segment of the nephron during a dehydration body. Its gene is AVP located on human chromosome 20.


2. The right answer is - Increased Secretion of Vasopressin To Maintain Less Loss Of Water.

Vasopressin has an antidiuretic action: it decreases the volume of urine by increasing the water permeability of the collecting tube. It binds to the V2 receptor, which is coupled to a Gα protein, which activates a signaling cascade through the PKA. This causes the synthesis of aquaporin 2 (transmembrane pore) as well as its translocation to the apical / urinary membrane.

Name two conditions that must be met for a reliable Gram staining result.
Hatshy [7]

Answer:

The two important conditions that must be met before gram staining are-

1. The age of the culture should not exceed 24 hours.

2. Over heating, decolonization should be avoided.

Explanation:

Gram staining is a technique developed to distinguish the bacteria on the basis of the composition of the cell wall around the bacteria.

The gram stain is a sensitive technique so must be performed carefully.  The precautions should be taken to avoid any error while gram staining that is-

1. Age of the culture- The culture should be freshly prepared just 18-24 hours before the experiment as above 24 hours bacteria lose their ability to retain the color so one would not be able to differentiate between the cultures.

2. While performing the experiment one should avoid overheating and decolorization with ethanol as both the factors lead to the loss of crystal violet stain from the cell and they take pinkish color after safranin staying.
