Answer:
Frogs and toads produce a rich variety of sounds, calls, and songs during their courtship and mating rituals. The callers, usually males, make stereotyped sounds in order to advertise their location, their mating readiness and their willingness to defend their territory; listeners respond to the calls by return calling, by approach, and by going silent. These responses have been shown to be important for species recognition, mate assessment, and localization. Beginning with the pioneering experiments of Robert Capranica in the 1930s[1] using playback techniques with normal and synthetic calls, behavioral biologists and neurobiologists have teamed up to use frogs and toads as a model system for understanding the auditory function and evolution. It is now considered an important example of the neural basis of animal behavior, because of the simplicity of the sounds, the relative ease with which neurophysiological recordings can be made from the auditory nerve, and the reliability of localization behavior. Acoustic communication is essential for the frog's survival in both territorial defense and in localization and attraction of mates. Sounds from frogs travel through the air, through water, and through the substrate. The neural basis of communication and audition gives insights into the science of sound applied to human communication.
Explanation:
Answer:
.12 liters
Explanation:
if it give 5ml an hour, it would give 120ml in 24 hours which is only equal to .12 liters.
Your answers would be:
1. ---- B. A cell cannot be subdivided into smaller units that maintain the living state.
2. ---- The organism is a eukaryote because it has a nucleus.
3. ---- D. Water would flow into them because they are hypertonic to external environment.
If you want to know why:
1. The cell is the basic unit of life or in other words, its the smallest unit that makes up a living thing. It does not subdivided further if you are talking about sustaining life. Yes, it is made up of smaller units of organelles, but these organelles work together as a single unit (as a cell), to do life sustaining processes.
2. The organism is a eukaryote because of the presence of a nucleus. This is one of the main features of a eukaryote that differentiates it from a prokaryote. Prokaryotes to not have a true nucleus.
3. Water would flow into them, causing the cell to swell and eventually burst if the concentration of solutes would not even out before then. The process of osmosis is what brings the water into the cell. The cell would have a higher solute concentration than freshwater. Through osmosis, the water would then go to the area of higher concentration, which would be the cell.
