Answer:
Nitrogen-fixing bacteria, microorganisms capable of transforming atmospheric nitrogen into fixed nitrogen (inorganic compounds usable by plants). More than 90 percent of all nitrogen fixation is effected by these organisms, which thus play an important role in the nitrogen cycle.

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made up of protein and a single molecule of deoxyribonucleic acid (DNA).
The unique structure of chromosomes keeps DNA tightly wrapped around spool- like proteins, called histones. Without this kind of packaging, DNA molecules would be too long to fit inside the cells.
DNA molecules in a single human cell if unwound from their histones and placed end to end, they would measure 6 feet in length.
Chromosomes play a key part in ensuring that DNA is accurately copied and distributed to new daughter cells as the parent cell divides to form new cells.
Answer:
166.7 V/m or 166.7 J/C
Explanation:
The formula for electric field is
volts/distance
Given
volts = 5V
Distance =0.03m
= 5V / 0.03m
= 166.7 V/m
Recall
1 V/m = 1 J/C
The magnitude of the electric field between the two electrodes in ionization type detectors = 166.7 V/m or 166.7 J/C
