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.

How do absorption, reflection, and refraction change the movement of P waves?
Answer:
Absorption, reflection and refraction will all change of the movement of P waves. Absorption will reduce the energy of the waves. Reflection will bounce the waves back. Refraction will change the angle of the waves based on what they are bouncing off of.

Transcription is the process that must happen in order to make
Answer:
a protein
Explanation:
Transcription is one of the three main, necessary events needed for proteins to form in a cell. This happens when DNA is transcribed to mRNA. Thymine (T) is subbed in by Uracil (U), so when transcribing, A's turn into U's, not T's.

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.

How much more kinetic energy does your car have when it changes its speed from 16 km per hour to 80 km per hour
Answer:
The correct answer would be - 25 times more.
Explanation:
The kinetic energy of a moving object increases with the increase in the speed of the object. It is evident that the kinetic energy of a moving object increases as the square of its velocity or speed. It means if a car moves with the speed of 32 km/hr has four times as much kinetic energy as the car moving with 16 km/hr.
Similarly, if a car changes its speed from 16 to 80 km/hr the kinetic energy will be -
= (80/16)^2
= (5)^2
= 25 times more.
Thus, the correct answer would be - 25 times.
The correct answer would be - 25 times more.

Answer:
energy pyramid
Explanation:
An energy pyramid is a model that shows the flow of energy from one trophic level to the next along a food chain.
The cycle of energy is based on the flow of energy through different trophic levels in an ecosystem. ...

Answer:
The virus uses the cell's genetic material to replicate its viral genome
Explanation:
During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material within hence further during the uncoating and replication, and assembly, the viral DNA or RNA incorporates itself into the host cell's genetic material and induces it to replicate the viral genome.
