Which of the following correctly sequences the stages of engine operation?A. Intake, power, compression, exhaust
B. Power, intake, compression, exhaust
C. Intake, compression, power, exhaust
D. Exhaust, compression, intake, power

Answers

The correct sequence of engine operation is given by option C. intake, power, compression and exhaust. The first step is the intake of air, in the case of petrol engines, fuel is taken in as well. The second step is compression. The third step is combustion or power, in this part, the fuel is injected. The last step is exhaustion which refers to the blowing out of the waste gases from combustion.

Which of the following correctly sequences the stages of engine operation?

A. Exhaust, compression, intake, power

B. Intake, power, compression, exhaust

C. Power, intake, compression, exhaust

D. Intake, compression, power, exhaust

"Proteinuria occurs when the filtration membrane becomes leaky, allowing proteins to cross. This impacts the blood colloid osmotic pressure by ____________________ the osmolarity gradient between the blood and filtrate, thereby ________________ the strength of this pressure."

Answers

Answer:

Proteinuria occurs when the filtration membrane becomes leaky, allowing proteins to cross. This impacts the blood colloid osmotic pressure by decreasing the osmolarity gradient between the blood and filtrate, thereby reducing the strength of this pressure.

Explanation:

Proteinuria is the medical term that describes the presence of proteins in the urine.Proteins, in normal conditions, are not capable of filtrating through the membrane but, in the presence of a disease, this is possible.

Proteins are responsible for the colloid osmotic pressure in the blood vessels, so when proteins get filtered, this pressure decreases and so does the osmolarity gradient between the blood and filtrate. The decrease in osmolarity gradient also produces a decrease of the colloid osmotic pressure because the strength of the pressure is as big as the gradient between the two compartments.

What will be the effect of placing a plant cell in a hypotonic solution? A) The plant will wilt. B) The cell will shrink in size. C) The cell will remain unaffected. D) The cell will expand and become turgid.

Answers

 D) The cell will expand and become turgid.

The plant cell will basically absorb all the water by osmosis and swell, but because it has a cell wall it will become turgid.
D. Hypotonic means the solution is greater inside the cell than outside the cell. In plant cells, this causes the vacuoles to become turgid.

A person's temperature is 40° C. What would it be in Kelvin? A. −313° CB. −313 KC. 313° CD. 313 K

Answers

Answer: The correct answer is D) 313 K

The temperature of the person = 40⁰ C

We know that, 0⁰ Celsius = 273.15 Kelvin

This means that in order to calculate the Kelvin temperature, 273.15 is added to the Celsius temperature.

Thus, the temperature of the person in kelvin = 273.15 + 40

                                                                             = 313.13 K

                                                                             ≈ 313 K

Thus, option D) is the right answer.


40°C= 313.1500K
