Sour receptors occur primarily along the sides of the tongue and are stimulated mainly by acids. Salt receptors are most common in the tip and upper front portion of the tongue. They are stimulated mainly by inorganic salts. Bitter receptors are located toward the back of the tongue
hopefully this helps but i could be really wrong lol
The barnacles are only able to attach them selfs to surfaces in the water. Since the surface is limited, barnacles are attaching themselves to the other barnacles, crowding the rock. The muscles were not able to grow or attach themselves off the surface of the rock. Same thing with the mussels that are growing on the rock. So not only barnacles are crowding the rock, but Mussels as well are crowding the rock.
The options provided for the question above are as follows:
A. Respiratory tract illnesses
B. Skin infection
C. Acute infectious diaherea
D. Intestinal infections.
The correction option is A.
Respiratory tract illnesses account for the majority of sickness that occur in child care settings. Such infection include those that affect the lower and the upper respiratory tracts; examples include: otitis media, sinusitis, bronchiolitis, pneumonia, etc. Children who attend out of home child care has greater risk of contacting these diseases.
The preferred prey item would be frogs.
What is optimal foraging theory?
It is a theory in ecology that proposes that predating animals that get the most energy from minimal efforts are favored by natural selection.
In order words, selection forces prefer investing minimum energy in order to extract maximally available energy.
In this case, the heron needs to use the lowest time to harvest the maximum energy possible. Since all the preys offer the same amount of energy, the one that requires the lowest time would be preferable for the heron.
In other words, frogs would be the most preferable prey.
