.Answer:
Option A, fix nitrogen inside nodules on the roots of legumes
Explanation:
Rizhobium bacteria live in symbiotic relationship with roots of leguminous plants such as pulses including alfalfa, soybean etc.
Rhizobium or Bradyrhizobium is a gram negative bacteria that satisfies the nitrogen starvation of host plant.
These bacteria get habitation and nutrition from these leguminous plants and in return they fix the nitrogen into the nodules of the roots. This is a kind of facultative association between soil bacteria rizhobium and legume plants.

Answer:
Neuron would be unable to receive signal from environment and previous neuron.
Explanation:
A neuron cell comprises of dendrites, cell body and axon. Dendrites are the projections of neuron cells that receive the electrochemical signal from other neurons and transfer them to soma (body) of a neuron cell. While axon transfer it to next neuron from cell body.
So if the mutation cause loss of dendrites of neuron cells it would be unable to receive the signal from the previous neuron and environment because receptors to receive signals are present on dendrites. Consequently the cell would loss the communication with other cell and that cell may dies and it can also cause paralysis of that particular area because of loss of communication.
Answer:
There are many types of challenges are faced by the scientists in 21st century. some are as given below:
Explanation:
1. Getting biodiversity. We're losing species at a disturbing rate, and we have to comprehend what the implications of that may be.
2. sustainable development. Like feasible agriculture, yet more broad sense. Discovering approaches to accommodate human needs while limiting the mischief we cause to the earth is urgent.
3. Everything about hereditary qualities. It's simply so much fun.
4. The most effective method to cut across political, social, and social limits and spur enormous and little scope activity to lessen biodiversity loss. This point may have a hefty sociology component, yet it's significant. All the natural and biological information on the planet won't make any difference on the off chance that we can't get individuals to follow up on it.
Most of their diet was various meats, however as agriculture was developed they began to eat more grains/vegetables.
