<h3><u>Answer;</u></h3>
increase the temperature from 27 degrees celsius to 37 degrees celsius
<h3><u>Explanation;</u></h3>
- The rate of an enzyme-catalyzed reaction increases as the temperature is raised.
- <em><u>The human body is maintained at 37°C as this is the temperature at which the enzymes in our body work best. Therefore increasing the temperature from 27 degrees Celsius to 37 degrees Celsius increases enzyme activity and in turn increases the production of amino acid in the flask.</u></em>
- Higher temperatures than 37° C which is the optimum temperature, disrupt the shape of the active site, which will reduce enyzme activity, or prevent it from working, in other words the enzyme will have been denatured.

For any question comment me
Answer:
7.5 m/s²
Explanation:
The following data were obtained from the question:
Initial velocity (u) = 21 m/s
Final velocity (v) = 36 m/s
Time (t) = 2 secs
Acceleration (a) =..?
The acceleration of an object is simply defined as the rate of change of velocity of the object with time. Mathematically, it is represented as:
Acceleration (a) = (final velocity (v) – initial velocity (u)) / time (t)
a = (v – u)/t
With the above formula, we can determine the acceleration of the roller coaster as follow:
a = (v – u)/t
a = (36 – 21)/2
a = 15/2
a = 7.5 m/s²
Therefore, the acceleration of the roller coaster is 7.5 m/s².
The combustion reaction is as expressed,
CxHy + O2 --> CO2 + H2O
The mass fraction of carbon in CO2 is 3/11. Hence,
mass of C in CO2 = (3.14 g)(3/11) = 0.86 g C.
Given that we have 1 g of the hydrocarbon, the mass of H is equal to 0.14 g.
moles of C = 0.86 g C / 12 g = 0.0713
moles of H = 0.14 g H / 1 g = 0.14
The empirical formula for the hydrocarbon is therefore, CH₂.
Answer:
It could pollute other planets. Nuclear waste might be attracted by the gravitational pull of the sun and disintegrate there instead. The waste storage spacecraft could crash into a planet, moon, or another astronomical body. It could be dangerous for other life forms out there.
