Not sure this is a question but my answer would be a semi-permeable membrane? Hope this helps! <3
B. By mutating their DNA in response to environmental conditions to gain beneficial traits.
Explanation:
Invading infectious diseases can, in theory, lead to the extinction of host populations, particularly if reservoir species are present or if disease transmission is frequency-dependent.
<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
