the test
tube must be swirled at a steady rate to facilitate the liberation of CO2 gas from the
solution
The reaction vessel should be submerged in the water bath as far as possible to keep the
entire contents at the temperature of the water bath. There is a valve attached to the rubber stopper that should be open
while attaching the assembly to the test tube, and then closed just before the start of data collection
Answer:
Option A, shared their data with colleagues to obtain feedback on the work.
Explanation:
All researchers prefer to share their findings with their peers or other researchers working in the same field to get their reviews. This step is very essential as it makes the research authentic and removes the flaws that would have otherwise missed by the researcher.
Peer reviewers also give useful suggestion to further modify one’s research study based on their experiences.
Hence, option A is correct
Answer:
<h2>411.86 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula

m is the mass
v is the velocity
From the question we have

We have the final answer as
<h3>411.86 J</h3>
Hope this helps you
Answer:
A
Explanation:
A. The optimum pH of the enzyme is 6.6. - this is true. The optimum pH of the enzyme is where its activity is the highest. On the graph, this is pH 6.6 (activity at 100)
B. The optimum pH of the enzyme is 5.8. - this is false, the activity of the enzyme peaks at 6.6 (100), at 5.8 the activity is 80
C. The enzyme's activity is greater around pH 8.0 than around pH 5.0 - This is false, the activity at pH 5 is 50, whereas at around 8 it is 20.
D
. The enzyme's activity continually increases as pH increases from 5.0 to 9.0 - this is false. The activity drops between pH 6.6 and pH 9.
Answer:
Biotic interacting with biotic is the answer.
Explanation:
Biotic=Alive such as plants,animal,and human.
Abiotic=Non-living
