Answer:
The urease will not catalyze any reaction.
Explanation:
The hydrolysis reaction of urea is:
(NH₂)₂CO + 2 H₂O + H⁺ ⇒ 2 NH₄⁺ + HCO₃⁻
Urease is an enzyme that catalyzes the urea hydrolysis reaction. Enzymes are very specific referring to the substrates they catalyze. If the solution does not contain urea, the urease will not bind to any of the substances in the solution, so it will not catalyze any reaction in the solution.
From the stomach, the food travels to the small intestine. This happens with the help of a movement known as peristalsis. Juices are released in the small intestine, which helps in the breakdown of carbohydrates, starch, and proteins.
Answer:
tropical rain forests and savannas
Explanation:
Tropical rainforests are found near the equator due to the amount of rainfall and the amount of sunshine these areas receive. ...
savannas-Because of their warm climate requirements, savannas tend to be found closer to the equator, which marks the halfway point between the north and south hemispheres of the earth. Because this area gets direct sunlight more of the year than the north and south extremes, the temperature doesn't change much.
The formula used for determining gas pressure, volume and temperature interaction would be PV=nRT.
<span>• What is the temperature in Kelvins?
</span>You already right at this part. Kelvin temperature formula from celsius should be:
K= C+273.15=
<span>K= 27 +273.15 = 300.15
It is important to remember that the formula in this question is using Kelvin unit at temperature, not Celcius or Fahrenheit.

<span>• Assuming that everything else remains constant, what will happen to the pressure if the temperature decreases to -15 ºC?
</span>In this case, the temperature is decreased from 27C into -15C and you asked the change in the pressure.
Using PV=nRT formula, you can derive that the temperature will be directly related to pressure. If the temperature decreased, the pressure will be decreased too.
<span> If you increase the number of moles to 6 moles, increase temperature to 400K and reduce the volume to 25 L, what will the new pressure be?
</span>PV=nRT
P= nRT/V
P= 6 moles* <span>0.0821 L*atm/(mol*K) * 400K/25L= 7.8816 atm</span>
