Answer:
D. A molecule of glucose
Explanation:
Potential energy is defined as the energy that is stored, or conserved, in an object or substance. The act of contracting muscles, emitting light flashes, flying or water moving are all dissipating energy and, thus, do not represent an example of kinetic energy. On the other hand, a molecule of glucose stores energy and therefore is an example of potential energy.
Answer:
They found evidence of an impact crater in Mexico
Explanation:
The K-Pg boundary is the boundary between the Cretaceous period and the Paleogene period, but also marking the end of the Mesozoic era and the beginning of the Cenozoic era. This boundary is dated to roughly 66 million years ago. The K-Pg boundary is characterized with a mass extinction. The dominant organisms on Earth all died out, including the dinosaurs, both terrestrial and aquatic, as well as the flying reptilians, with only the birds surviving from that super-family. The reason for the mass extinction has been an impact with an asteroid or a comet, that was very large and hit the Earth where the Yucatan Peninsula in modern day Mexico is located. The impact was devastating, with heat waves, tsunamis, earthquakes, triggering of the majority of the volcanoes, wildfires, all combined managed to devastate the environment, thus big portion of the species living in it as well. The lucky survivors were smaller organisms, and the mammals turned out to be the most successful in occupying the empty niches and have became the dominant organisms on the planet.
Biofilms are resistant to antimicrobial chemicals due to genetic diversity.
<h3>How do biofilms increase antibiotic resistance?</h3>
Biofilms are considered as a reservoir of genetic diversity. The emergence and spread of antibiotic resistance genes increase in biofilm due to horizontal gene transfer (HGT).
HGT can happen through the transfer of plasmids among microorganism cells in a biofilm through conjugation so that's why the antimicrobial resistance is higher in a biofilm than in free-floating bacterial cells.
