Homeostasis is a self-regulating technique by which systems
in the body maintain stability and tend to adjust to optimal conditions which
are essential for survival. Thereby, the role of homeostasis is to help the
body maintain constant internal environment. A good example of homeostasis
would be ‘drinking excess alcohol causes vomiting’.
Answer:
microvilli, actin filaments
Explanation:
The apical ends of intestinal cells face the intestinal channel and have long processes that facilitate the absorption of nutrients. the name of these processes is microvilli and actin filaments from the cytoskeletal element forms their internal skeleton.
Answer:
The main difference between Prokaryotic and Eukaryotic cell is that, eukaryotes contain membrane bound organelles like nucleus where as prokaryotes do not. The genetic material is present at the center and is called nucleoid in prokaryotes.
Explanation:
Example of prokaryotes include bacteria and archea bacteria. Examples of eukaryotes include plants and animals. Prokaryotes lack organelles such as mitochondria, endoplasmic resticulum and lysosomes which are present in eukaryotes. Both the groups contain ribosomes but its 70s ribosome in prokaryotes and 80s ribosomes in eukaryotes.
