Nitrogen.


Plants cannot use atmospheric nitrogen directly. Nitrogen from the air must be converted into the different form so plants can absorb it. Thus plants need nitrogen-fixing bacteria to convert atmospheric nitrogen into ammonium, which is available for plants to absorb it.

Deffense [45]

Answer:

The correct answer is- have diverse cell wall composition

Explanation:

Bacteria and archaea are both prokaryotes because they both lack membrane-bound nucleus and other membrane-bound organelle. There are differences between bacteria and archaea which allow their differentiation into two different domains.

One of the main difference is the difference in their cell wall. The cell wall of bacteria is made up of peptidoglycan and the cell wall of archaea is made up of pseudo-peptidoglycan.

In peptidoglycan N-acetylglucosamine and N-acetylglucosamine are the two sugars but in archaea N-acetyltalosaminuronic acid (NAT) replaces NAM.

5. Studying light from a star allows us to… a. determine a star's temperature b. determine what elements the star is made of c.
Basile [38]

Answer:

The correct answer is option C "determine how a star is moving (toward, away, fast, slow)"

Explanation:

All realized components emanate and assimilate specific frequencies of light, which is important for the electromagnetic range. By considering the frequencies of light (as demonstrated by 'lines' inside the electromagnetic range) discharged by an object in space, astronomers can get a scope of information.

One thing they look at is the adjustment in situation of lines in the range from a star this can tell astronomers the distance away the star is, regardless of whether it is moving towards or away from us and how quick it is moving.
