Answer:
The best way to classify two different organisms that have similar appearance and are found in the same environment is to use gel-electrophoresis to compare DNA patterns.
Explanation:
When organism possesses the same physical characteristics and are found in the same environment the genetic test must be varried out to ascertain their differences such as DNA test using electrophoresis to compare such
Answer:
B) increased exchange surface provided by their membranes
Explanation:
Alveoli are tiny air sacs that are responsible for exchanging oxygen (O2) and carbon dioxide (CO2) in the lungs. Alveoli have elastic fibers in order to expand and recoil depending on the volume of air breathed in. The alveolar epithelial cells (pneumocytes) may adopt a shape that serves to increase the surface area of gas exchange. On the other hand, intestinal epithelial cells have microvilli, which are microscopic projections in the plasma membrane. Microvilli serve to increase the cell's surface area, thereby facilitating the absorption of nutrients and water.
The answer is A, and this is true because trauma can not be transmitted or caught by humans or animals but a virus , faulty nutrition & congenital defects can. hope this helps :)
The answer is c mitochondria and aerobically
