Homologous organs or structures have the same ancestry but different functions such as the human arm, the bat's wing and the dog's leg. All originate in the mammal's common ancestor. Over time, these structures have evolved and changed their purpose to better suit their current environments.

Analogous organs are the opposite. They have similar functions but different evolutionary origins. The wings in swallows and dragonflies are such an example.

Thus, the correct interpretation is B. Swallows and dragonflies have analogous organs, which indicates that their wings evolved differently.

Give two reasons why dna evidence analysis is an imperfect science
Virty [35]

Answer:

DNA samples might be planted and it is possible to synthesize a nucleotide sequence to incriminate a person

Explanation:

In a criminal case, DNA evidence may be considered to be fraudulent because DNA samples might be planted around the crime scene. Moreover, specific genomic profiles of an individual stored in the database can be used to manufacture a DNA sample matching this profile without the necessity to obtain tissues of the person. In consequence, DNA evidence may be considered to be imperfect. Nonetheless, it is important to highlight that DNA evidence is one of the most important modern advances used during criminal trials, and it has proven to be a very useful (and effective) tool available in law enforcement.

Cells, like bacteria and archaea, that do not have a nucleus in their cells have traditionally been called _____.
Montano1993 [528]

Cells, like bacteria and archaea, that do not have a nucleus in their cells have traditionally been called prokaryotes.

<h3>What are prokaryotic cells?</h3>

Prokaryotes are organisms whose cell (or cells) are characterized by the absence of a nucleus or any other membrane-bound organelles.

Prokaryotic cells are opposed to their eukaryotic counterparts that possess a membrane-bound nucleus that houses their genetic material (DNA).

Examples of prokaryotes are as follows:

  • Bacteria
  • Archeaebacteria

Therefore, cells, like bacteria and archaea, that do not have a nucleus in their cells have traditionally been called prokaryotes.

If all fungi in an environment that perform decomposition were to suddenly die, then which group of organisms should benefit mos
Nata [24]

Answer:

prokaryotes

Explanation:

Prokaryotics will be the next group after fungus that will benefit if all the fungus were to die a sudden death.

As the protist group consist of mostly disease causing organisms and plants are one that take the benefit from the decomposed material while animals are the those that feed on organisms from first and second tropic level.

Prokaryotes mostly have single celled organisms such as bacteria which help in decomposition of the organic waste left by the higher organisms
