<h2>Evolutionary analysis of organisms</h2>

Explanation:

  • Some organisms, which were characterized together determined to genetically very different .
  • Using the analysis of RNA developed by Carl Woese, scientists are now able to classify  the human evolution
  • living things based on genetic information instead of expressed characteristics.
  • Genetic  information is more specific and can give clues as to the evolutionary ancestry of  organisms.
  • That is the reason adding of various domains in previous system of classification is allowed for a comparison of species genetic code

What is free nitrogen?
UNO [17]

Answer:

Nitrogen thet cannot be used by organisms. C.

Explanation:

Free nitrogen is simply molecular nitrogen (N2). Nitrogen, in its molecular form, consists of two nitrogen atoms bound together with a tripple bond. Because it is very stable, N2 is typically nonreactive, and takes a lot of energy to break them apart. Among these are the amino acids necessary for life to begin and which are the building blocks DNA is made from. Basically, any nitrogen that is in an organic compound is considered “fixed” nitrogen and N2 is considered to be “free” nitrogen

The more ________________ the homologous structure, the more likely they _______________ shared a common ancestor
Natali [406]

The more numbers of the homologous structure, the more likely they have recently shared a common ancestor.

Explanation:

Homologous organs are defined as those organs which do have different functions but a similar basic structure which denotes the divergent evolution. Homologous organs are seen in species that are very close to each other which are more related with each other in terms of evolution. For example, a bird is more close to each man than a fish, so do share more homologous organs common to man than fishes do. Examples of the homologous organs are hands of human and wings of birds. They have same basic structure like skeletal structure which is humerus, radius, ulna, carpals, metacarpals and phalanges. They are similar in structure but have different functions like flying in birds and gathering food in humans.
