Explanation:
The DNA hyperchromic effect can be defined as the absorbance of radiation or light by the nitrogen bases of DNA. This phenomena is effective when the DNA is in single stranded condition. For observing the hyperchormic effect the DNA is required to be denatured at high temperature or by increasing the level of pH.
The two strands of the DNA when get separated the absorbance of the DNA solution also increases. This results due to reduction in the base-base interaction and hence, increases the absorbance of light like UV by the bases.
Yeasts and algae is an example of eukaryotic organism
The doppler effect changes the wavelength of the light emitted, depending upon whether source is moving away or coming towards the detector.
Answer: Water erosion
A scientist observes the ocean tides moving large amounts of sand away from the beach is a evidence for natural process which is known as water erosion. Water erosion is a process of removal or detachment of upper soil layers from its's original place due to the effect of water. The rate of erosion may be rapid or slow depending upon the soil, the landscape and weather conditions. The beach exhibit sandy soil whose particles are not connected or aggregated with each other and not with the surface over which it is present. Therefore, sand being loose soil is taken away by oceanic tides due to water erosion.
