B. Eukaryotic species experience a greater rate of mutations within their populations.
C. Mutations increase the genetic diversity in both prokaryotes and eukaryotes.
D. Sexually reproducing eukaryotes evolve faster than species that reproduce asexually.
Answer:
C. Mutations increase the genetic diversity in both prokaryotes and eukaryotes.
Explanation:
It is a well-established fact that mutations increase the genetic diversity in living organisms (especially if they are positive mutations). The positive and faster mutations will help the organism to develop better traits for survival in the changing environments.
The other options are incorrect because of the following reasons:
A. Eukaryotes don't do gene transfer via conjugation.
B. Eukaryotic species don't experience a greater rate of mutations as compared to the prokaryotes. Prokaryotes have a faster mutation rate. This is the reason that microbes can adapt to changing environments faster than humans or other multicellular organisms.
D. As mentioned above, sexually reproducing eukaryotic species evolves slower than the asexually reproducing species. For example, evolution in bacteria (e.g. drug resistance) is faster than any organism belonging to eukaryotic lineage.
Answer:

Mucus protects the lining of the stomach from acidic gastric juices.
Hydrochloric acid (HCl), lipase, and pepsin come together specifically in gastric juice. Its primary purpose is to render ingested bacteria inactive, preventing infectious pathogens from entering the intestine.
Squamous epithelium, like the skin, is found in the mucosa of the mouth and the esophagus and is thought to serve as a barrier against infection.
Gastric juice makes food particles soluble, starts digestion (especially of proteins), and transforms the contents of the stomach into a semiliquid material termed chyme, laying the groundwork for subsequent small intestine digestion.
Therefore, Mucus protects the lining of the stomach from acidic gastric juices.

scientists observed a key characteristic that required reclassification. What
was that characteristic? *
Reclassification of fungi
Explanation:
Fungi were classified under kingdom plantae by the earlier taxonomists due to their similarities. Both of them were grown on the ground and fixed to the ground, they do not move, fungi like plants also produced fruiting bodies.
However, there were many physiological, morphological, genetic, and biochemical features which were unique and different from other kingdoms.
Although, the fungi contain similar features like vacuoles, secondary metabolites, myecelial root-like structures; fungi like plants do not have a complete vascular system.
Hence, the previous classification under plants was reconsidered and fungi were reclassified as a separate kingdom next to the protists and before the plantae kingdoms.
