The tadpole contains gills but doesn't have legs nor lungs.
however the adult frog contains the opposite. It has both lungs and legs but doesn't have gills. This is due to tadpole leaves in the water and the frog leaves on both land and sometimes in the water.
If you apply white light and it reflects only red, you see it red, all the other wavelentghs absorbed. If it reflects all wavelength (i think listed all red-orange....) then it should be white.
<span>Two main characteristics that distinguish autotrophs from heterotrophs are:
A~ Autotrophs produce their own food by either chemosynthesis or photosynthesis. Heterotrophs do not produce their own food. Heterotrophs obtain their food by consuming autotrophs or heterotrophs.
B~ Autotrophs are at the primary level in a food chain and Heterotrophs are at the secondary level or tertiary level in a food chain.</span>
Answer:
Respiratory bronchiole
Explanation:
The respiratory bronchioles represent the narrowest airways within the lung, being continuations of terminal bronchioles that have approx. 0.5 mm in size. The epithelium of the respiratory bronchiole is composed of cuboidal ciliated cells and a small number of non-ciliated (secretory) Clara cells. The respiratory bronchioles lead into alveolar ducts composed of smooth muscle and connective tissue (i.e., elastin and collagen), connecting the respiratory bronchioles to the alveolar sacs.
