NITROGEN FIXING BACTERIA processes nitrogen in the atmosphere and make it available to other living forms in a usable form. Nitrogen fixing bacteria are micro organisms which are capable of transforming atmospheric nitrogen into fixed nitrogen. An example of a nitrogen fixing bacteria are bacteria in the genera azotobacter.
Answer:
The kinetochore of the chromosomes
Explanation:
<em>What could be damaged that is hindering the spindle fibers from attaching to the chromosomes are the kinetochores of the chromosomes.</em>
At the metaphase stage of the cell division, the chromosomes align at the equator of the cell and the spindle fibers engage each chromosome at a region known as the kinetochore.
The kinetochore is made up of complex proteins and lies around the centromere region of the chromosome. The microtubules of the spindle fibers attach to this region during the metaphase stage.
<u>If the kinetochore is damaged, it means the spindle fiber will not be able to attach to the chromosome. </u>
Green plants use their chlorophyll to capture the energy of sunlight and split water molecules. As they do, they release oxygen into the air. Green plants use energy from the sunlight and carbon dioxide from the air to make sugar. In effect, they create “mass” from “gas.”
Yes, the trachea would collapse in this situation.
The trachea is a tube composed of cartilage which connects the pharynx and larynx to the lungs. It is a critical structure for all air-breathing animals and its main responsibility is to facilitate the passage of air. The trachea is surrounded by several c-shaped and incomplete cartilaginous rings which prevent it from collapsing.
