What is the solute potential (ΨS ) of a 3.0 M NaCL solution at 27°C under standard atmospheric conditions?
Answer:
149.58 bars
Explanation:
The solute potential (ΨS) of a solution is given by:
ΨS = iCRT
Where i = ionization constant of the solution, C = molar concentration of the solution, R = pressure constant =0.0831 liter bars/mole-K, and T = temperature in Kelvin.
NaCl dissociates in water to give Na and Cl ions, hence, i = 2
T = 27 + 273 = 300 Kelvin
C = 3.0 M
ΨS = 2 x 3 x 0.0831 x 300
= 149.58 bars.

Why do cells spend the least time in telophase?
Answer:
Anaphase is the shortest phase of mitosis. In anaphase, the sister chromatids are pulled apart to opposite ends of the cell. In metaphase, chromosomes line up along the metaphase plate.Metaphase takes a short amount of time to complete. Telophase is the next to the shortest phase of mitosis after anaphase.

The maximum air temperature permitted for delivery vehicles when receiving shell eggs Shell eggs Receive at an air temperature of 45°F (7°C) or lower.
In which case one can reject the delivery?When receiving raw shell eggs you must reject the delivery if they don't conform to the standard range of conditions. Raw egg shells at temperature of 45°F or below should be rejected during delivery as a result of the possibility of the presence of pathogens on them which exposes individuals to diseases.
The common pathogen found in eggs is Salmonella which causes typhoid. All egg shells should be treated at higher temperatures in order to destroy them.

-it is a portable energy source used in Barbecue grills in hot air balloons
what is it?
The gas that Dr. Walter Snelling discovered in 1911 that becomes a liquid under moderate pressure and acts as an energy source is propane.
Properties of PropanePropane is a gas at room temperature and it was isolated by Dr. Walter Snelling around 1911 in the process of trying to stabilize gasoline.
At cold temperatures or moderate pressure, propane becomes a liquid.
Propane has been and is still being used as an energy source in cooking, powering vehicles, and cutting metals in industrial welding.

Role of hormones in bullet points
Please help!
Answer:
There is growing evidence to indicate that age-related declines in growth hormone (GH), insulin-like growth factor (IGF)-1, and androgen and estrogen production play a role in the pathogenesis of sarcopenia (an age-related decline in muscle mass and quality). Although GH supplementation has been reported to increase lean body mass in elderly individuals, the high incidence of adverse effects combined with a very high cost has limited the applicability of this form of therapy. The assessment of an alternative approach to enhance the GH/IGF-1 axis in the elderly by using GH-releasing hormone and other secretagogues is currently under way and is showing some promise. Testosterone replacement therapy may increase muscle mass and strength and decrease body fat in hypogonadal elderly men. Long-term randomised, controlled trials are needed, however, to better define the risk-benefit ratio of this form of therapy before it can be recommended. Available data are currently insufficient to decide what role estrogen replacement therapy may play in the management of sarcopenia. Therefore, although the evidence linking age-related hormonal changes to the development of sarcopenia is rapidly growing, it is still too early to determine the clinical utility of hormonal supplementation in the management of sarcopenia.
