Why can't prokaryotic species be defined as a group of similar organisms that could sexually reproduce together?
s344n2d4d5 [400]

Answer:

The prokaryote divides by asexual mode of reproduction.

Explanation:

The concept of species which defines a species as a group of individuals of a population which can interbred and produce a fertile progeny is applicable to the organism which can reproduce sexually.

Since the bacteria divide through asexual means and not through sexual ways therefore the concept of defining a species becomes complicated and does not apply.However the concept of species in prokaryotes is still a topic of research.  

Thus, the biological concept of species is not applicable to prokaryotes.

Which of the following is true of retroviruses? (3 points)
Nikitich [7]

Answer:

Explanation:

A retrovirus is an RNA virus that is duplicated in a host cell using the reverse transcriptase enzyme to produce DNA from its RNA genome. The DNA is then incorporated into the host’s genome by an integrase enzyme. The virus thereafter replicates as part of the host cell’s DNA. Retroviruses are enveloped viruses that belong to the viral family Retroviridae. A special variant of retroviruses are endogenous retroviruses, which are integrated into the genome of the host and inherited across generations. Endogenous retroviruses are a type of transposon.
