<h2>
Answer:</h2>
Option B) Nodules.
<h2>
Explanation:</h2>
- It is impossible for plants to fix atmospheric nitrogen(nitrogen present in soil) and hence they absorb nitrogen from the soil in the form of nitrates and ammonium.
- Plant absorbs nitrogen from soil through nodules present on roots.
- In case of leguminous(pulses) plant roots of the plant form a symbiotic association with nitrogen-fixing bacteria for example- Rhizobium.
- On the other hand if nitrates is directly absorbed by the plant, it is taken up by nitrate transporters which uses a proton gradient to power the nitrate to get transported.
- Absorbed nitrogen is transferred from root to shoot by xylem.
Result: Option B) is the correct answer.
Answer:
0.00004524 minute
Explanation:
The enzyme is Catalase, and it speeds up the rate of reaction by 700 times than what it was supposed to be.
If the already sped up rate of reaction is 1.9 seconds, then the initial reaction ought to have taken
1.9/700 seconds and that is 0.0027143 second.
We're asked to convert to minute, we then have
0.0027143/60 which is equal to 0.0000452381 minute.
Since we're asked to round off to 4 significant figure, we have 0.00004524 minute.
