Answer:
need a picture to answer this question
Answer:
The chromosomes are pulled away from one another from the metaphase plate. Subsequently, all the chromosomes to 1 side are pulled one way, and all the chromosomes on the opposite side are pulled the other way. In the long run, every haploid cell would possibly contain either just maternal or fatherly chromosomes if traverse didn't happen.
<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.

Phosphorus<span> uptake by </span>plants<span>. </span>Plants<span> take up </span>phosphorus<span> from the soil solution as orthophosphate ion: either HPO4-2 or H2PO4-. The proportion in which these two forms are absorbed is determined by the soil pH, when at higher soil pH more HPO4-2 is taken up.</span>
