Weathering, plate movements and volcanoes destroyed many of the craters.
Answer: Waves are defined as energy transferred from one place to another. The way in which the energy travels is called the medium. These waves can be in the form vibrations through light or matter, such as solid, liquid, or gas (e.g. sound waves or earthquakes). The most important terms in relation to these waves are wavelength, frequency and amplitude.
Wavelength is directly related to frequency because it describes the displacement between the waves, whereas frequency describes how many waves pass within a second. Larger wavelengths are associated with lower frequencies, and smaller wavelengths are associated with higher frequencies.
Answer:
50.
Explanation:
The independent assortment means the segregation of one pair of trait is not dependent on the other pair of trait. These traits are present on the different chromosome.
The crossing between w+m+/wm female and wm/wm male results in the progeny as w+m/wm (non-parental progeny)-25% ,w+m+/wm (parental progeny)-25%, wm/wm (parental progeny)-25% and wm+/wm(non-parental progeny)-25%. Total 50% progeny are non parental type.
Thus, the correct answer is option (B).
