Answer:
The correct answer is "natural selection in Staphylococcus aureus populations".
Explanation:
Natural selection is a process at which populations of organisms develop advantageous traits under the premise of survival of the fittest. In this case, the continuous exposure to penicillin and other antibiotics since 1940s have a natural selection effect in Staphylococcus aureus populations, allowing an increase in antibiotic-resistant alleles in the bacteria, which acts as an advantageous trait for them. Antibiotic resistance is a serious medical concern that has been addressed by a culture of responsible use of antibiotics and development of novel treatments for infections.
Answer:
<h2>All deuterostomes exhibit radial symmetry in their bodies.</h2>
Explanation:
deuterostomes : All deuterostomes are triploblastic and have 3 layers:
i) endoderm, ii) mesoderm and iii) Ectoderm
In deuterostomes , a mouth that develops separately from the blastopore.
Taxonomically, the deuterostomes defines as any member of the phyla (Chordata, Hemichordata, Echinodermata, etc) in which the anus appears first, and it develops at or near the blastopore.
All deuterostomes have a coelom.
All deuterostomes have a similar pattern of early embryonic development.
I think the correct answer from the choices listed above is option D. A prokaryote that release energy if it is in an environment without oxygen and dies when exposed to oxygen, and uses fermentation would most likely be an obligate anaerobe. Obligate anaerobes<span> are poisoned by oxygen, so they gather at the bottom of the tube where the oxygen concentration is lowest.</span>
