The energy is directly proportional to the frequency and inversely proportional to the wavelength.
The frequency is inversely proportional to the wavelength, so it follows that short wavelength are energetic than long wavelength.
The term frequency refers to how the particles vibrate, when a flow moves through a medium.
The total number of full vibrations per unit time is used to calculate frequency.
A wave have the frequency of 2000 vibrations per second and Hertz unit of measurement for frequency.
Wavelength is defined as the difference between a crests and troughs of a wave.
The space between these crests or troughs in case of low-frequency wave is more than in a high-frequency wave.
The unit used to the unit of measurement of wavelength is nanometer.

The best example of physical weathering is as follows:
Thus, the correct option for this question is B.
Weathering may be defined as a process through which numerous rocks and minerals found on the earth's surface are considerably broken down into smaller fragments. The process of weathering is facilitated by different components like water, wind, ice, etc.
Physical weathering may be defined as a type of process that stimulates the disintegration of rocks, minerals, and soil components without undergoing any chemical change. Some examples of physical weathering are as follows:
Therefore, plant roots grow through concrete and split represents a process of biological activities or root wedging. So, the correct option for this question is B.

Answer:
Plant roots growing through concrete and splitting it.
Xylem is one of the two types of transport tissue in vascular plants, phloem being the other. The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients.
Answer:
it helps in transport of water and minerals vertically(only in one direction)
Explanation:
The factors are: The size of the sample, the extraction method, the method of purification and preservation of the DNA.
The quantity and quality of DNA can be greatly improved by performing PCR.
* Purification of nucleic acids is a key step for functional studies in biology. Because of the great diversity of living organisms in nature, purification becomes a real challenge for researchers, especially cell lysis.
The evolution of lysis methods has made it possible to improve efficiency, speed and simplicity. But, this lysis step remains a crucial step for the efficiency and the quality of the purification.
