Which of the following will occur if a prokaryotic cell is placed in a solution that has a higher concentration of solutes (that

cannot readily diffuse across the plasma membrane) than does the cytoplasm of the cell?

Answer:

This Question is incomplete

Explanation:

What is needed to be understood here is the concept of hypertonic and hypotonic solutions and their effects on cells.

Hypertonic solution is a solution in which the concentration of the solutes outside of the cell is greater than inside (in the cytoplasm) of the cell while hypotonic solution is a solution in which the concentration of solutes inside of the cell (in the cytoplasm) is greater than outside of the cell.

From the above, we can deduce that the question is about the effect of placing a prokaryotic cell in a hypertonic solution. When a prokaryotic cell is placed in a hypertonic solution, water moves (through osmosis) from inside of the cell to the outside environment causing the prokaryotic cell to shrink.

Human blood typically contains 1.04 kg/L of platelets. A 1.89 pints of blood would contain what mass (in grams) of platelets
Fynjy0 [20]

Answer:

The correct answer is 930 grams platelets.

Explanation:

The volume of blood given is 1.89 pints. Total number of gallons in 1.89 pints is,  

= 1.89/8 = 0.236 gallon

1 gallon comprise = 3.785 L

So, 0.236 gallon comprise = 0.236 * 3.785 L = 0.89 L

As mentioned that 1 Liter of blood comprise 1.04 kilograms of platelets. Therefore, 0.89 L of blood will contain = 1.04 * 0.89 = 0.93 Kg platelets

1 Kg contain 1000 grams. So, number of platelets in grams will be,  

= 1000 * 0.93 = 930 grams platelets.

The burning of a sample of propane
r-ruslan [8.4K]

Answer:

70.0°C

Explanation:

We are given;

  • Amount of heat generated by propane as 104.6 kJ or 104600 Joules
  • Mass of water is 500 g
  • Initial temperature as 20.0 ° C

We are required to determine the final temperature of water;

Taking the initial temperature is x°C

We know that the specific heat of water is 4.18 J/g°C

Quantity of heat = Mass × specific heat × change in temperature

In this case;

Change in temp =(x-20)° C

Therefore;

104600 J = 500 g × 4.18 J/g°C × (x-20)

104600 J = 2090x -41800

146400 = 2090 x

  x = 70.0479

     =70.0 °C

Thus, the final temperature of water is 70.0°C
