Trophic Levels describe the transfer and different stages of the organisms transferring energy. I just called it Trophic level energy flow in school.
Explanation:
the kind of cell it is is unipotent cell
From what we know, we can confirm that a variation that makes a gene different in some way from other genes for the same characteristics is called a mutation.
<h3>What is a mutation?</h3>
All genes in an organism are coded through a series of nucleotides. Each gene has its own sequence of nucleotides that make it unique. A mutation is a change in this nucleotide sequence caused by either external forces such as <u>UV light</u>, or <u>internal</u> <u>errors</u>.
Therefore, given the definition described, we can confirm that a variation that makes a gene different in some way from other genes for the same characteristics is called a mutation.

<span>Shale rock is most likely to be changed to slate during regional metamorphism. it is a mix of mud, clay minerals, quartz and calcite. It is the most common sedimentary rock. this rock is formed by the deposition of slow moving water mainly in lake,river etc.Black skales are rich in unoxidised carbon.</span>
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.
