Answer:
Nitrogen-fixing bacteria
Explanation:
These type of bacteria living in the soil or symbiotic interaction with root plants has the ability to transform the atmospheric nitrogen (N2) into ammonia (NH3), in this form many organisms like plants can metabolise. Bacterial genera like <em>Azotobacter </em>spp.<em>, Rhizobium </em>spp.<em>, Azospirilum </em>spp.<em>,</em> etc. can make the transformation of nitrogen by specialized enzymes called nitrogenases.
Answer:
The living things in order to maintain is homeostasis
If a nutrient is short in supply, it will limit the organisms growth.
A) Rest and motion are relative terms
Answer:
Nucleic Acids
Explanation:
Nucleic acids are DNA and RNA and they are the molecules responsible for containing the genetic material of all living beings. Thus, DNA and RNA are the molecules responsible for establishing the variability and different characteristics between dog breeds, through the genetic information that each of them houses.
In this case, among the options given in the question above, we can confirm that if Allen has studied the genetic material of dogs to better understand why there are so many different breeds, he must have studied nucleic acids.
