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:
<span>The most obvious patter is that A binds with T and C with G, as is the case with DNA.
The beginning of DNA transcription starts with the binding of the enzyme RNA polymerase to the promoter region. Next, RNA moves begins transcribing in the 5' to 3' direction using one strand of DNA as the template strand. This strand of RNA produced is complimentary with the other strand known as the coding strand except that Thymine is replaced by Uracil. To cleave the strand Bacteria can use what is known as Rho-independent termination where the strand makes a hairpin loop that causes stress and breakage. Or Rho-dependent termination where a protein causes an interaction between the template and mRNA and they disassociate. Termination is not really understood in eukaryotic organisms.</span><span>

Answer;
The offsprings will be such that , a normal vision female, a heterozygous female, normal male and a colorblind male.
Explanation;
-Most X-linked traits in humans are recessive. One example of an X-linked trait is red-green colorblindness. Let (Xc) represent the recessive allele that causes colorblindness and (XC) represent the normal dominant allele. Females that are XCXC or XCXc have normal color vision, while XcXc females are colorblind. For males with; XcY are color blind, while those with XCY are have normal color vision.
Heterozygous female, XcXC
Normal male, XCY
The offspring of the parents, XcXC x XCY, are: XcXC (heterozygous female), XCXC( normal vision female), XCY (normal vision male), XcY (color blind male).

The niche of grasshopper would include the plant species it eats.
Explanation:
The niche of an organism is different to that of a habitat. A niche includes the interaction between organisms and the food that they eat, whereas, a habitat is a place where organisms are provided with food, protection and shelter.
Habitat is a place of ecosystem that involves other environmental factors like- rain, sunlight, humidity etc. So, food type eaten by grasshopper would be the description of a niche and not a habitat.
