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 accurately describes the function of the electron transport system (ETS)?
SVEN [57.7K]
You are familiar with the electron transport system in photosynthesis that takes light energy and converts it to chemical bond energy in the form of ATP and NADPH. This electron transport chain in cellular respiration will take the energy stored in NADH and FADH2 during the Krebs cycle and convert it to chemical bond energy in the form of ATP. In eukaryotes, this reaction takes place on the inner mitochondrial membrane, as is shown in Figure 4.26. Prokaryotes that undergo aerobic respiration also have an electron transport chain located within their plasma membrane, which may be highly folded similar to the inner membrane of the mitochondrion. Thats the answer my friend hope it helps

goblinko [34]

The phrase 'some animals exhibit similar proteins' describes how biological chemicals provide evidence to support that life changes over time.

<h3>What is evolution?</h3>

Evolution refers to descendence with modification, which means that proteins are similar in related species.

Protein building blocks (amino acids) can also change over evolutionary time due to descendence with modification.

In conclusion, the phrase 'some animals exhibit similar proteins' describes how biological chemicals provide evidence to support that life changes over time.
